FLEXCRETE CEMENTITIOUS COATING 851

Flexcrete Cementitious Coating 851 is a two component, thixotropic, cementitious modified polymer coating with high adhesion to both concrete and steel.

Flexcrete Cementitious Coating 851 provides internal and external structural waterproofing for concrete and other mineral substrates. It resists both positive and negative pressure under a 100m water head in water-retaining and below-ground structures, as well as on roofs and decks. It also protects against chloride ingress on highway and coastal structures and enhances the durability of reinforced concrete by reinstating effective cover to meet the specified design life.

This two-component, thixotropic, cementitious polymer-modified coating adheres strongly to both concrete and steel. It forms a hard, highly alkaline layer with a degree of elasticity that protects concrete and other substrates from aggressive acid gases, moisture, and chlorides. Additionally, it offers significantly improved chemical resistance. It performs especially well in sulphate-contaminated ground conditions. You can reinforce it with Cemprotec 2000-S tape to accommodate movement around details and across cracks and joints where further movement is likely.

Advantages.

Incorporates the latest proven cement chemistry, microsilica, fibre and styrene acrylic copolymer technology.
Brush, trowel or spray applied normally in two coats. Floors and decks are a one coat application.
Pre-packaged material only require mixing on site.
Excellent adhesion to sound prepared concrete substrates and steel.
Dense matrix offers low permeability to water, even at 10 bar positive and negative pressure, and very high diffusion resistance to carbon dioxide gas and chloride ions.
Provides the equivalent to 100mm of good quality concrete cover.
Non-toxic when cured and is listed as authorised under Regulation 31 for use in the supply of drinking water.
Easily overcoated with Flexcrete’s specialist membranes to provide further protection and aesthetic quality.
