Pro Seal 770 is a pure acrylic polymer which is ideal for medium to high porosity sealing applications. This makes it an excellent limestone sealer. The polymer penetrates deep into the substrate and forms a strong but flexible matrix. This provides strength and stability to friable materials. These properties enable Pro Seal 770 to protect limestone and other soft materials from erosion and premature weathering.
Pro Seal 770 is also an great colour stabiliser. It will, therefore, enhance and prolong the colour fastness of all oxide coloured concrete materials. Pro Seal 770 is also cementitious compatible. This means it can be used as an admix for poured applications. Used as an admix binder for screeds and toppings it adds both strength and colour enhancement.
Pro Seal 770 is a very good, UV stable, primer. It has excellent bridging capabilities. It will fill up the larger pores in highly porous substrates. This will ensure final coats of Pro Seal 896 do not penetrate too deep into the material. Instead it will remain near the surface where it is most needed. As such using Pro Seal 770 as a pre sealer will result in better product coverage and lower total sealing costs.
Pro Seal 770 is not as stain and wear resistant as Pro Seal 896 & Pro Seal 898. Use as a stand alone sealer in low traffic areas. It is ideal for sealing retaining walls, garden features and feature limestone. However, high traffic and high staining environments benefit from an extra layer of protection. Apply a final seal coat of Pro Seal 896 for best results. Or use Pro Seal 898 for extra gloss.
Pro Seal 770 is also an excellent grouting binder for polishing concrete floors. It binds fine grinding dust to fill in voids and small pores when used in the polishing process.
