Waterproofing Primers and Additives

Waterproofing primers and additives serve as essential first steps in creating an effective waterproof barrier for any structure. Waterproofing primers prepare substrates for waterproofing by improving adhesion. While waterproofing additives are substances that are mixed into the primary waterproofing material or substrates to enhance various properties. Additives also allow for customisation in the waterproofing process, ensuring the properties of the waterproofing material are specific to the requirements of projects.

From commercial interior spaces to industrial exterior applications, both primers and additives ensure a robust, uniform and long-lasting waterproofing layer, preventing moisture penetration long-term.

At Komerco, we have a range of waterproofing primers for different substrates including concrete, cement, metal, wood, glass, tile, stone, asphalt and bitumen, masonry, renders and screeds, plasterboards, wet area linings, roofing, tin, aluminium, copper, brass, ceramic, concrete, plasters and more. We also have an array of additives for different applications, each with varied specifications and levels of viscosity. We stock products from globally recognised suppliers like Ardex, Gripset, Normet and Mapei.
