WHY USE A SEALER?
​
Protecting cement finishes with a good quality Cemcrete sealer is crucial and not only makes the surface easier to clean, it offers other benefits as well, such as enriching the colour intensity of the overlay, blocking the penetration of stains, and improving water repellency and abrasion resistance.
​

SEALER PRIMER  |  Acrylic co-polymer (water-based)

Description	Sealer primer to pre-seal cementitious surfaces prior to applying the final sealer of your choice. Provides a tough, clear priming system for sealers onto decorative cement coatings, concrete, cement plaster, & masonry. It reduces the porosity ensuring better sealer application.
​Benefits ​	Reduces porosity (allows for better spread rate of sealer)  Provides adhesion between substrate & final sealer Helps retain colour when using solvent-based sealers UV stable Non-yellowing
​Packaging	1, 5 & 20 litre containers
​Coverage	​Approximately 5 - 6m² per litre per coat
Curing	​Initial set: Solvents evaporate after 2 days plus Final cure: 14 days
Finish	​White - dries transparent

Description ​	Twin pack, acrylic modified, aliphatic polyurethane coating formulated to obtain a UV stable, non-chalking, high gloss finish with excellent gloss retention.
Benefits ​	UV stable Excellent resistance to weathering Superior flexibility High abrasion resistant Acid, alkali & solvent resistant Bonds to various substrates; concrete, metal, wood, tiles and natural stone Dries rapidly to a slick durable and desirable finish
​Finish	Transparent Gloss (also available in Matt)
​Packaging	Two Component 5L
Coverage	Approximately 7 - 8m²/ litre
Curing	Surface Dry: 4 hours Walk On: 6 - 8 hours ​Overcoat Time: Minimum 5 hours but within 24 hours ​Final Cure: 5 days

CRETESEAL WATER-BASED  |  Polyurethane acrylic water-based sealer

Description ​	An innovative water-based PUD / Acrylic sealer for uncoated cement, decorative cement finishes, stone, slasto and tiles.
​Benefits ​​	Available in Satin Sheen Reduces the chance of efflorescence & water absorption Highlights natural colour of tiles, screeds & slasto if applied directly Excellent chemical resistance against a range of domestic / light​ industrial chemicals Stops staining of the tiles & slasto, especially around braai areas Non-flammable Contains only low levels of VOC (EU regulations)
​Finish	​Satin Sheen
Packaging	1, 5 & 20 litre containers
​Coverage	Approximately 8 - 10m²/ litre for the first coat and 10 - 12m²/ litre for subsequent coats although the spreading rate will vary with porosity and type of substrate
​Curing	Initial set: 6 - 8 hours ​Final cure: 7 - 10 days

MULTIPURPOSE SOLVENT-BASED SEALER  |  Solvent-based acrylic sealer

Description	A clear thermoplastic sealer that provides a tough, durable, flexible, penetrating coating on surfaces of concrete, cement plaster & masonry.
Value	Available in both Gloss and Matt finish options UV resistant & non-yellowing Enhances colour if applied directly Protects the surface from the ingress of dirt & grease Water-fast Good binding properties on friable surfaces
Finish	Transparent Gloss or Matt finish
Packaging	​1, 5 & 25 litre containers (Matt only available in 1 & 5 litre)
​Coverage	First Coat: Approximately 4 - 8m² per litre per coat Subsequent Coats: Should require less sealer than first coat
​Curing	Initial set: 2 to 3 hours depending on the weather ​Final cure: 7 days

MULTIPURPOSE WATER-BASED SEALER  |  Non-yellowing clear polymer sealer

Description ​​	​A clear polymer emulsion that provides a tough, durable coating on vertical surfaces of concrete, cement plaster & masonry.
​Benefits	Available in Gloss & Super Matt options UV resistant Non-yellowing Alkali resistant Carbon dioxide tight (protects steel re-enforcing)
​Finish	​Transparent Gloss or Super Matt
​Packaging	1, 5 & 20 litre containers
Coverage	Approximately 5 - 6m² per litre per coat
​Curing	Initial set: 4 hours ​Final cure: 3 days

SILICONSEAL SOLVENT-BASED |  Penetrative sealer (Wet-on-wet application)

Description ​	A colourless, water-based, low viscosity, penetrating liquid for hydrophobic infusing & priming of mineral surfaces. When applied to mineral substrates, it will reduce the capillary absorption of the substrate which it has penetrated but does not clog pores or capillaries. There is therefore little or no impairment of the building material’s ability to “breathe”.
​Benefits	Greatly reduces the water absorption of concrete, clay bricks, natural stones, fibre cement and plaster Used for the prevention of rising damp in brick walls Does not darken or change the colour of the surface
​Finish	No colour or sheen effect on surface
​Packaging	1, 5 & 25 litre containers
​Coverage	Face bricks - 6m²/litre Porous bricks - 3m²/litre Concrete - 4m²/litre
​Curing	Initial set: Solvents evaporate after 2 days plus Final cure: 22 days

SILICONSEAL WATER-BASED |  Penetrative waterproofing system

Description ​	​A milky white, water-based, low viscosity, penetrating liquid for hydrophobic infusing & priming of mineral surfaces. When applied to mineral substrates, it will reduce the capillary absorption of the substrate which it has penetrated but does not clog pores or capillaries. There is therefore little or no impairment of the building material’s ability to “breathe”.
​Benefits	Greatly reduces the water absorption of concrete, clay bricks, natural stones, fibre cement and plaster Used for the prevention of rising damp in brick walls Does not darken or change the colour of the surface Can be used as a water-repellent primer for emulsion paints & plasters, silicone resin emulsion paints & silicon resin plasters Contains only low levels of VOC (EU regulations)
​Finish	Milky white liquid which dries clear
​Packaging	1, 5 & 20 litre containers
​Coverage	Face bricks - 6m²/litre Porous bricks - 3m²/litre Concrete - 4m²/litre
​Curing	​Initial set: 2 to 3 days depending on the weather to allow the water to fully evaporate Final cure: 14 days

SLIP RESISTANT ADDITIVE  |  White fine granules

Description ​	Fine, white granules to increase the slip-resistance of sealers on floors.
​Benefits	​Disperses readily & evenly throughout the sealer Generally increases abrasion resistance of sealers Compatible with solvent-based & water-based systems Does not detract from aesthetic appeal of most decorative surfaces. In some cases it enhances the appearance
​Finish	May leave a slight opaque sheen on darker surfaces
​Packaging	Supplied in bags of  90g’s (enough for 5 litre)
​Coverage	Depends on type of sealer used. Refer to the relevant sealer's datasheet
​Curing	Depends on type of sealer used. Refer to the relevant sealer's datasheet
