The surface to be treated should be clean and free of all contaminants. The surface can be damp or wet, however FluoroSeal should not be applied to a surface that has pools of water. The pools should be removed using a broom or cloth prior to application. Do not apply FluoroSeal if rain is expected within 24 hours of application. Do not apply if extreme weather conditions are expected. Do not apply if surface temperatures are above 30 degC. If necessary, cool the surface with water prior to application. FluoroSeal is ready to apply and should be mixed well before use. A test prior to application must be performed to assess the suitability of the product. FluoroSeal is best applied using a low-pressure sprayer. The surface should be uniformly applied to saturation point. Do not allow pooling of sealer. Pools can be spread out using a soft bristled broom. Excess sealer must be removed before drying. Protect adjacent surfaces such as glass, metal or painted surfaces from any overspray. Full curing may take up to 24 hours. Avoid traffic for at least 24 hours. Equipment clean up can be performed with water.

Si20-D – Water Based Sealer Densifier Si20-D – Water Based Sealer Densifier
Si20-D – Water Based Sealer Densifier $65.00
Si20-D is a ready to apply, sodium silicate based densifier, hardener and dust proofer for concrete and cementitious substrates. Si20-D penetrates concrete and reacts to form a permanent Calcium Silicate Hydrate (CSH) structure within the pores. Treated surfaces are harder and stronger with a permanently reduced porosity reducing the movement of water and minimising efflorescence. Key advantages Significantly increases density, hardness and strength Excellent dust proofing of substrates Significantly reduces movement of water Minimises efflorescence High penetration into masonry surfaces High wear resistance, UV stable, long life Can be applied to damp or wet substrates
Si20-DS – Water Based Sealer and Densifier Si20-DS – Water Based Sealer and Densifier
Si20-DS – Water Based Sealer and Densifier $80.00
Si20-DS is a water based silicate and siliconate densifier-water repellent sealer for use on most types of porous limestone and concrete building materials. Si Densifiers & Moisture Barriers – Silicates Si Chemistry: Silicate based densifiers and moisture barriers are alkaline solutions containing soluble metal silicate salts. They are small molecules that when applied onto a substrate penetrate deep below the surface. They chemically react with cementitious substrates to form a cross-linked silicate polymer that permanently blocks substrate capillaries reducing the movement of water. The substrate becomes significantly denser, harder and stronger and is less susceptible to dusting. Key advantages Significantly increases density, hardness and strength Excellent dust proofing of substrates Significantly reduces movement of water Minimises efflorescence High penetration into masonry surfaces High wear resistance, UV stable, long life Can be applied to damp or wet substrates
