Description

Mapei Isolastic – Latex Additive

Mapei Isolastic – Latex Additive To Impart Elasticity to Cement Based Adhesives. Isolastic is a type of latex mixed into Kerabond, Kerabond T, Kerabond Plus and Adesilex P10, undiluted or diluted 1:1 with water. Mapei Isolastic is a very fluid, pinkish-white liquid composed of a water dispersion of an extremely elastic polymer, which, when mixed with cement based adhesives, improves adhesion to all substrates, deformability and impermeability, once hydration has taken place.

All substrates receiving Kerabond, Kerabond T, Kerabond Plus or Adesilex P10 + Isolastic must be flat, mechanically strong, free from loose parts, grease, oil, paint, wax, etc. Precast concrete elements or in situ concrete must be cured for at least 3 months in favourable weather conditions. Cementitious substrates must not be subject to shrinkage once the tiles have been installed, therefore in warm weather renders should be cured at least one week per centimetre of thickness. Cementitious screeds must have an overall cure of at least 28 days unless they have been made with the special MAPEI binders for screeds such as Mapecem, Mapecem Pronto, Topcem or Topcem Pronto. Surfaces that are too ho due to exposure to direct sunlight should be cooled by dampening them with water. Gypsum substrates and anhydrite screeds must be perfectly dry sufficiently hard and free from dust. They must always be treated with Primer G or Eco Prim T. Areas subject to extreme damp must be primed with Primer S.
