weber.cote primer
Anti-carbonation coatings provide protection of both repaired and unrepaired areas, designed to offer low permeability to carbon dioxide but adequate permeability to allow the escape of water vapour.
weber.cote anti-carbonation coatings are based on polymer dispersions formulated to give a film thickness in the range 150 to 500µm to provide a two-coat barrier. The thicker elastomeric coatings have crack-bridging capability and are essential for protecting structures where some movement is expected. weber.cote coatings are exceptionally durable with a minimum life expectancy of 15 years and can be applied to most building materials by brush, roller or spray…
