Our Approach
At CSW Coatings we don't get too creative when it comes to naming our products. We call our concrete sealer, "Concrete Sealer", our paving sealer "Paving Sealer" and so on! 
This same simple approach is also adopted for our penetrating sealer options. In a nutshell we have a Standard range, Deluxe range and Premium range penetrating sealer. We then simply take this a step further and name our water based products WB, and our solvent based products SB.

Expected Wear* : Lifespan as indicated may be achieved in many applications. Application method, cleaning methods, substrate type, exposure to elements and traffic will affect wear. The use of solvents, acids and alkalis will seriously reduce a sealers lifespan.
It is recommended a sealer be frequently tested and re-applied where above such harsh conditions exist or as necessary. See Expected Wear
Why Offer 3 Types?
With sealer you really do get what you pay for. Each time an additional protective quality is added to the manufacturing end, it has a knock on effect to the price a consumer will ultimately pay! It is for this reason that CSW Coatings has attempted to cater to the consumers needs by not making you overpay for a "one size fits all" penetrating sealer. What we mean by this is:
Example 1... say you have a sandstone retaining wall and your main concern is to protect it against moisture attack. You probably aren't the least bit interested in protecting against wine stains and the like. So in this particular example, why pay for the added stain protection?
Example 2... say you have an concrete patio that you frequently use as an entertainment area. Regularly, you invite guests over that unfortunately spill anything from coffee to wine. In this particular scenario you really are after complete protection. Your prepared to pay that little bit extra in order have peace of mind!
How Do They Work?
Film Vs Penetrating
To generalise, there are two main types of sealers:
Film Forming and Penetrating!
Image 1 illustrates the altering of appearance by using a film forming sealer.
Image 2 illustrates the natural look non-slip protection of a penetrating sealer!
Each is unique and has its place!
Film Forming Sealer.
Film forming sealers create a protective film on your surface to protect it from moisture as well as regular wear and tear. They are also known as topical or surface sealers. Here are some of the benefits of a film forming concrete sealer:
1. They bring out the beauty of your surface by enhancing and darkening its colour with a semi-gloss or gloss finish.
2. They prevent contaminants such as dirt, oil, grease and chemicals from penetrating the surface, protecting it from damage as well as making it easier to clean and maintain.
3. They are repellents preventing contaminant damage.
4. Protects your surface from wear and tear and exposure to the elements.
5. Fast-drying, especially water based with some being touch dry in as little as 20 mins.
There are three types of film forming concrete sealers:
1. Acrylic sealers. These are the most cost effective film-forming sealers and also the easiest to apply. They are available in water-based and solvent-based varieties.
2. Urethanes. These are slightly thicker than regular acrylic sealers and offer good protection against chemicals and abrasive substances, as well as protection against scuffs and stains.
3. Epoxies. These can be used for both interior and exterior installations. Some are specifically manufactured for internal applications since they might turn yellow if exposed to UV rays. CSW Coatings supplies UV stable, non-yellowing external epoxies in addition to internal. They are available in clear or pigmented variants. Epoxies consist of two components that must be mixed together before being painted on.
Film Forming Suitable Substrates are not limited to: Concrete, Brick, Pavers, Decorative Stencil and Stamped Concrete.
Penetrating Sealer.
Penetrating Sealers Offer Non-slip Protection!
Most hard surfaces are prone to foreign particles and pollutants. Like our skin, concrete and natural stone also have pores where dust particles and foreign spillage can seep through. These particles can be detrimental to your hard surfaces structure as time moves on. This can result in staining, cracks and breaks. For most homeowners, replacement can be a financial burden.
One way to enhance the life of your surface is with the help of penetrating sealers. A penetrating or impregnating sealer can prevent chemical damage and permanent staining by holding spills close to ones surface.
Penetrating sealers can make concrete floors to granite countertops more resistant to organic materials while still allowing surface to breath.
Here are some of the benefits of a penetrating natural stone or concrete sealer:
1. Suitable For Natural Stone Surfaces as retains a natural look.
2. Non-Slip - best for trafficable areas where slip resistance is a concern.
Penetrating suitable substrates are not limited to: Concrete, Brick, Pavers, Grout, Sandstone, Limestone, Granite, Travertine, Porcelain, Slate and Terracotta.

Keep in mind though that even after finding out the differences between a film forming and penetrating sealer, it is still important to choose the right brand available on the market. Look for a product that is safe to use, easy to apply, while still maintaining all the protective qualities one would expect from a sealer.
For the Do-It-Yourself market, applying a water based sealer will be substantially easier than a solvent!
Water Vs Solvent Based
It is important to note that when discussing water or solvents, we are discussing the "carrier" only. To determine a sealers efficiency further, one must concentrate on the active constituents the carrier transports.
Advantages and Disadvantages
Solvent Based 
• A solvent typically will allow deeper penetration into a substrate than water.
• For dense substrates like semi vitrified porcelain, granite & marble, water will not penetrate whereas a solvent will.
• Can be cross-linked, therefore allowing a wider temperature window for application.
• Unaffected by cold weather exposure during storage and shipment.
• Generally not as cost effective as water based products.
• Evaporates at a faster rate than water based products therefore not advised to apply on hot days.
• Surface must be bone dry on application.
• Due to odours generated, can be problematic to apply indoors.
Water Based
• Excels in very porous surfaces as product does not penetrate as deep therefore requires less.
• Safer to use around people, children, pets and so forth.
• Non-hazardous, non-flammable, very low odour - all round more environmentally friendly.
• Excels in indoor applications.
• Often more cost effective than solvents.
• Much faster dry time than solvents.
• May be a positive: Does not have the same level of darkening as a solvent.
• Water based film forming chemistry does not allow for the same level of gloss achieved with a solvent.
• On application, less tolerant to environmental change. Humidity and dew points may have an effect.
• May be a negative: Does not have the same level of darkening as a solvent.

Reducing the amount of volatile organic substances (VOC, or volatile organic compounds) is a topic that is frequently discussed nowadays, mainly because national regulations are now urging more and more to lower the levels of VOC in most paints and coatings.
Owing to these greater restrictions, it is now more important to know what comprises different kinds of sealers, because they may contain a VOC anywhere from lower than 100 g/L (very low) to higher than 400 g/L (very high). Knowing the VOC helps you find out the type of sealer that suits your project best.
There are two variants of concrete (stone) sealers: water-based sealers with usually low VOC, and solvent-based sealers with usually high VOC. Both used in concrete coatings; they can act both as decoration and protection. After the concrete is cured, usually 21-28 days, these sealers are applied. Their decorative functions can make the concrete glossier as well as to enhance colour, thus improving aesthetic quality. Their protective functions are to shield the concrete from damage as well as provide greater resistance to chemicals and stains.
Most film forming concrete sealers that are resistant to ultraviolet (UV) rays are 100%-based on acrylic polymers. Technological improvements now provide contractors with an opportunity to choose between different types of high-grade acrylic sealers that use water-based or solvent-based polymers. Both of them act to seal concrete with a continuous coat.
In a sealer that’s water-based, the particles comprising the polymer are scattered in water. After application of the sealer to the concrete, the water evaporates and the particles comprising the polymer begin gathering together. After more evaporation, the particles deform and then bind together...the result being a coating that’s continuous and clear.
In a sealer that’s solvent-based, however, the particles of the polymers are not dispersed. Instead, the polymer forms a clear and continuous solution with the solvent. As the solvent evaporates, the chains comprising the polymer are brought closer, and in time, they interlock firmly. Both solvent-based and water-based topical sealers stick to the surface of the concrete where they are applied; that is why upon application, eventually the surface of the concrete will look glossy.
For your projects, if you want to consider using water-based sealers, you should remember that both types of sealers (water-based and solvent-based) work in nearly the same way. Here are the similarities:
Strong And Long-Lasting. These are the most important attributes of any sealer; a sealer must function in protecting the surface. High-quality topical acrylic sealers can protect anywhere between 2-5 years outdoors. Both water and solvent based sealers also protect concrete from stains such as car stains, spills from food or drink, and chemicals – it is possible to remove these stains before they become permanent.
Can Be Applied Easily. Both types of sealers can be bought in ready-made, ready-to-apply mixtures. Depending on where they will be used, these sealers are often rolled-on or sprayed on concrete.
Resistance To Ultraviolet Light. Ultraviolet light can pass through 100%-acrylic sealers easily, so they won’t decompose compared to polymers, like nonaliphatic polyurethanes, styrene-based acrylics, and some types of epoxies, that absorb UV rays. Resistance to UV rays can result in protection for a longer period.
While water-based and solvent-based sealers have similarities, they also have variant differences, such as:
How They Look. This is a major difference between the two types of sealers. Sealers that are water-based look milky white upon application. This is because scattered polymer particles reflect visible light in a different way than the way water reflects visible light. The finish can be semi-gloss and matte. Sealers that are solvent-based on the other hand, are good in wetting out and penetrating surfaces of concrete, so the finish is glossy and the colour of the concrete underneath is intensified. The one drawback is generally the intense “wet look” of a cheap inferior solvent sealer can disappear quite quickly!
How They Are Handled. Water-based sealers do not burn, have no intoxicating smells typical of solvents and can be cleaned up easily and quickly after application. Saved time by busy contractors could spell the distinction between arriving on the job early and arriving home late.
Both types of sealers, however, do not differ much in their protective properties, and both can protect concrete surfaces extremely well. If you want a sealer with a low VOC, go for a water-based sealer; for it is strong and durable and you can work with it easily. Also bear in mind that washing up is also much easier when compared to a solvent!

Navigating Stone Sealers
As one of Australia’s largest suppliers of stone protection products we understand how selecting the correct product can be overwhelming. Most penetrating sealers can be applied to multiple porous substrates though for your convenience have broken down each category by stone.
Simply select your surface from our menu and filter with applicable options.
For example should you be wishing to seal travertine first select Travertine Sealer.
and filter by sub-menu like Carrier… Water based or Solvent Based?
Water Based sealers are typically more DIY friendly as they are slightly easier to apply and wash up with very little to no fumes.
Solvent Based products will typically penetrate deeper and excel with the denser more compact substrates.
Moisture Stains include water borne contaminants like: Efflorescence, Moss, Mould, and Algae.
Moisture & Oily Stains include all previous plus oil borne contaminants like Oil, Tea, Coffee, Wine and Graffiti.
Residential grade sealers offer protective qualities suitable for moderate traffic areas while the higher concentrate commercial grade offers advanced protective qualities suitable for high traffic areas.
Before applying any protective coating it is absolutely essential that the surface be prepared thoroughly. As there is always a trigger mechanism for coating failures our below guide will aid in eliminating such scenarios.
Remember... A Coating Is Only As Good As The Floor Prep!
The Number One Reason For Premature Sealer Failure Is Inadequate Preparation !!!
Film Forming Preparation
PRE APPLICATION TESTING
1. CONTAMINANTS
Contaminants such as oil or grease stains must be removed prior to any application.
Such techniques determined by applicators include degreasers, alkaline cleaners, hot water pressure washing and stiff broom agitation to name just a few.
2. HYDRATION - (2 Minute Water Test)
Concrete coatings and natural stone sealers are best applied to porous substrates. To test porosity apply a few drops of water to surface for a period of 2 minutes. After such time dab up using absorbent towelling. If surface darkens slightly or there is evidence of absorption this suggests surface is porous.
It is advisable to do a number of tests across the surface to ensure results are consistent.
3. MOISTURE - (Plastic Sheet Test)
Problems with floor coverings, such as bubbles, blisters, and de-lamination can occur when an impermeable floor coating or sealer traps excess moisture remaining in the slab.
Application of most coatings requires substrate to be free of dampness, discoloration, or damp odors. Water based sealers have some tolerance to moisture.
Determining if moisture is present is vital in preventing disappointment from a coating failure.
The most accurate method in determining moisture levels is by utilising a moisture meter.
If not feasible then the simple Plastic Sheet Method may be used.
Plastic Sheet Method
You can do this simply by cutting a piece of plastic sheeting and taping down the perimeter with duct tape to the surface of your floor.
After letting it sit for 24 hours, peel it up and look for any condensation on the underside of the plastic. Equally look for dark spots on the surface of the concrete. Water on the plastic or a dark spot on the concrete is created from moisture.
If none exists, this suggests excess moisture is not present.
If you do have some moisture then application of a coating should be delayed until re-testing indicates no moisture.
It is advisable to do a number of tests across the surface to ensure results are consistent.
Note temperature and dew point can affect this test.
Values and numbers indicated are general guidelines and recommendations and may not be applicable for some specific installations and conditions.
General
Apply to dust free, chemical free porous surfaces only.
Caution on new concrete, best to allow minimum 28 days curing prior to sealing (industry standard).
Solvents require surface to be bone dry for application. Water based sealers allow for some tolerance of moisture present.
Do not apply when surface temperatures are expected below 10 or greater than 28 degrees during cure.
Do not apply if rain is imminent.
Always mix product well prior to application.
Repeated thin, evenly spread coats are better than a heavy application. Do not apply thick.
Single packs apply using 10-12mm nap roller or pump sprayer for best effects.
Two packs apply using 14-16mm nap roller or squeegee.
Application must not be too thick as excessive build up may cause the coating to appear milky or increase risk of delamination.
Application of sealer over contaminants such as moisture and dirt may reduce adhesion and cause discolouration.
To eliminate many variables, a test patch is recommended for intending project substrate and on either of the following non-related surfaces (MDF board, uninstalled formed concrete, uninstalled stone).
Test patch should be applied to a small area first (approx. 1m2) and leave to dry to establish both suitability and coverage rate.
Coverage will vary depending on porosity of the surface and will range between 2sqm per litre on porous surfaces, and up to 12sq per litre on very smooth surfaces. Consult specific product page for recommended minimum/maximum spread rates.
Before applying the sealer, surfaces should be acid etched using a 5:1 hydrochloric acid wash.
Ensure all safety equipment is worn.
After the surface has reacted (approx. 20 mins), neutralise and wash the residue off with clean water.
Ensure that disposal of residue is in accordance with local laws.
Ensure the surface is clean and dry before applying sealer.
NEW CONCRETE FLOORS
New concrete floors should be allowed to cure at least 28 days (industry standard) before painting. Cracks and crevices should be filled to ensure a level surface. The entire surface must be thoroughly scrubbed with a hydrochloric acid solution, followed by thorough rinsing with neutraliser, clean water and complete drying.
Before painting ensure that the surface is free from dust, grease and any other contaminants. Never apply on very damp floor surfaces or onto surfaces known to suffer from rising damp. If surface suffers from rising damp apply a moisture barrier first.
OLD CONCRETE FLOORS
Remove and or repair any cracked or damaged areas to ensure a level surface. Remove all unsound paint by scraping and sanding. If the entire floor is unsound it may need to be abraded/grinded or sandblasted. The entire surface must be thoroughly scrubbed with a hydrochloric acid solution, followed by thorough rinsing with neutraliser, clean water and complete drying.
Before painting ensure that the surface is free from dust, grease and any other contaminants. Never apply on very damp floor surfaces or onto surfaces known to suffer from rising damp. If surface suffers from rising damp apply a moisture barrier first.
PREVIOUSLY PAINTED SINGLE PACK
Product can go straight over any sound existing coating. If any peeling/flaking parts these will need to be removed. A coating is only as good as its preparation so if applied to an unsound surface the risk of delamination increases.
If a single pack solvent were previously used then best to re-apply a solvent once more.
If a single pack water based were previously used then best to re-apply a water based product once more.
CSW Coatings supply both water and solvent based products.
If existing surface is not sound (peeling/flaking parts) these will need to be completely removed either chemically with a product like:
Floor Stripper
https://cswcoatings.com.au/product/floor-stripper/
or mechanically with sanding/grinding or sandblasting (determined by applicator).
Due to the many variables in the field CSW Coatings cannot advise on applying our products over specific competing brand products.
PREVIOUSLY PAINTED TWO-PACK EPOXY
Floors that have been previously painted with two-pack epoxy can be recoated. The entire surface must be thoroughly abraded, preferably by sanding or sandblasting, in order to achieve a sufficient key for the paint to adhere to. Any loose, peeling or flaking paint must be removed. The surface can be abraded with a belt sander, pole sander or angle grinder using coarse sandpaper or grinding discs. Sandblasting, sanding and grinding are the recommended techniques for preparation. Pressure washing is NOT an adequate preparation technique. Failure to adequately abrade the epoxy coating can result in failure of the topcoat. Once a sufficient grind has been achieved pressure wash the entire surface to remove any sanding residue, leave the surface to thoroughly dry. Repair any damaged areas with a cement/sand mixture, or suitable epoxy filler. Ensure that the repaired surface/s are appropriately abraded before applying the paint.
