Primer 4T

Primer 4T is a single-component water-based acrylic primer with low VOC content, with fine aggregates and ready to use. Suitable for obtaining a uniform absorption of micro-cements such as Microbond® and Ercole® on tiles and other substrates. The cementitious coating on ceramic tiles sometimes let the traces of the joints of the tiles emerge on the surface (tiles mirroring) due to a different level of absorption between ceramic surface and tile joint. Primer 4T evens the absorption of the Microcement between the tile and the joint so that you can obtain a uniform surface.
