Cemprotec EF Primer is used to stabilise and seal cementitious and asphalt floors prior to the application of the Cemprotec range of cementitious coatings and mortars. It can overcome some inadequacies in surface preparation and helps minimise the risk of out-gassing from the substrate.
Cemprotec EF Primer is a modified, styrene acrylic co-polymer impregnant with high penetration, which stabilises and seals cementitious and asphalt substrates. It further increases the adhesion of Cemprotec cementitious coatings and mortars and prevents rapid drying and out-gassing at the concrete interface on porous and inadequately saturated backgrounds.
