Sikagard-545 W Elastofill

Sikagard-545 W Elastofill is a flexible intermediate layer, filler and coating based on an acrylic copolymer dispersion. It forms part of a coating system comprising Sikagard®-551 S Elastic Primer (solvent-based) or Sikagard®-552 W Aquaprimer (water-based) as the primer, Sikagard®-545 W Elastofill as the intermediate layer and Sikagard®-550 W Elastic as the top coat. The material is water-dilutable, harmless to the environment and easy to apply. It offers excellent adhesion to concrete, the ability to fill small pores, blowholes and substrate irregularities, high resistance to carbon dioxide diffusion, good water vapour permeability, crack-bridging ability even at low temperatures (- 20°C), the option of producing a textured surface, and resistance to freeze-thaw cycles and de-icing salts.

Colour: grey (standard)

Sikagard-680 S

Sikagard-680 S is a single-component, solvent-based coating material based on methacrylic resin, resistant to weathering, ageing and alkalis. It is designed to form clear or coloured protective coatings on mineral substrates such as concrete and other cement-based materials. Sikagard-680 S protects concrete against aggressive weather conditions (its rapid drying makes the coating rain-resistant after a short time) and enhances the self-cleaning action of protected surfaces. It has no adverse effect on the concrete texture. The material has very high resistance to carbon dioxide diffusion, significantly reducing the progression and depth of concrete carbonation. The coating has virtually no effect on water evaporation from concrete, does not attract dirt particles and does not discolour under precipitation. It is very suitable for protecting fresh concrete.

• as a protective and decorative coating on concrete and other cement-based materials

• Sikagard-680 S Clear Glaze: a clear, glossy material used as a refreshing and protective coating for exposed-aggregate concrete
• Sikagard-680 S Top Coat: a coloured, matt top coat available in a wide colour range

• Sikagard -680 S Clear Glaze: clear
• Sikagard -680 S Top Coat: a wide choice of colours

Sikagard-700 S

Sikagard-700 S is a single-component material for protecting absorbent cementitious substrates. It penetrates the substrate pores. It is water-repellent while allowing water vapour diffusion in both directions. The product reduces capillary water uptake, improves resistance to frost and de-icing salts, reduces efflorescence, does not stain, limits the accumulation and penetration of dirt on the surface, improves thermal insulation properties, provides greater durability and resistance than other silicone impregnations, reduces chloride ion penetration into the substrate and does not affect water vapour permeability. Sikagard-700 S can be overcoated with dispersion coatings. It usually does not change the surface appearance.

• absorbent materials exposed to rain, such as concrete
• levelling layers
• concrete slabs
• fibre-cement products
• bricks (clay and lime, unglazed)
• natural stone

Sikagard-702 W Aquaphob

Sikagard-702 W Aquaphob is a silicone microemulsion concentrate that, when diluted with water, forms a water-repellent impregnation with high penetration ability. The material reduces capillary water uptake and absorption of aggressive aqueous solutions, does not alter the water vapour permeability of the impregnated surface, penetrates concrete substrates extremely well, does not change the surface appearance, improves resistance to dirt, limits fungal and mould growth and maintains high alkali resistance. It protects against precipitation and dampness.
