Sovereign Waterproofer is a plasticising and waterproofing additive for mortar and external renders. The use of Sovereign Waterproofer improves the workability of sand/cement without the addition of lime. Sovereign Waterproofer prevents water separation over time and provides a lovely smooth mix. Particularly suitable for use when pebble dashing.
Sovereign Waterproofer gives excellent workability to both mortars and renders. Once cured the cement mix will have a much reduced porosity leading to an extended service life. When building up layers of render the addition of Sovereign Waterproofer will reduce the suction of the initial coat reducing the likelihood of the top coat cracking due to flash drying. This is particularly useful when pebble dashing as the surface remains ‘wetter’ for longer allowing more time for the aggregate to be placed. Waterproofer can be used with other admixtures, e.g. rapid hardeners, but they should always be added separately, not together. The dilution factors should be adjusted where necessary.
