Why Waterproofing Primer is preferred in construction?
A waterproofing primer is a type of coating applied to surfaces before the main waterproofing material or membrane is installed. The purpose of a waterproofing primer is to enhance adhesion, improve the substrate's surface condition, and create a better bonding surface for the subsequent waterproofing layers. Primers are particularly useful on surfaces that might not readily accept adhesives or coatings due to their porosity or smoothness. Here are some key points to understand about waterproofing primers: 1. Adhesion Enhancement: One of the primary functions of a waterproofing primer is to improve the adhesion of the waterproofing material to the substrate. Some surfaces, like smooth concrete or certain types of masonry, may not provide a suitable surface for direct application of waterproofing materials. The primer helps create a better bond between the substrate and the waterproofing layer. 2. Substrate Sealing: Waterproofing Primer s can seal the substrate, reducing its por...
