Stabilises and Seals Cementitious & Asphalt Substrates


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.


  • Material is ready to use and can be brush or roller applied in one coat.
  • Further increases the adhesion of Cemprotec Cementitious Coatings and Mortars.
  • Economic surface impregnant.
