EnviroSeal X4 is a clear sealer and water repellent. Prevents freeze/thaw damage in freezing weather and mold damage in warmer weather.

EnviroSeal X4 is a water-based, solventless silane/siloxane emulsion. It is a high quality, general-purpose water repellant for impregnating and priming mineral surfaces. EnviroSeal X4 can be used for the mass treatment of non-load bearing concrete products.


EnviroSeal X4 reduces capillary absorption of the building which it has penetrated but does not clog pores or capillaries. Therefore there is little or no impairment of the building material’s ability to “breathe”.


  • EnviroSeal X4 is an excellent water repellent for many absorbent mineral substrates, such as bricks, sand-lime brick, natural sandstone and mineral plasters.
  • EnviroSeal X4 may also serve as a water repellant primer for emulsion paints and plasters, silicone resin emulsion paints and silicone resin plasters.
