TRA Deep Penetrating Primer is a one‑component, low‑viscosity composition based on a modified styrene‑acrylate copolymer with nanoparticles. Thanks to this, it penetrates deeply into absorbent substrates, reinforcing them and equalizing their absorbency. At the same time, it creates an ideal base as an adhesion bridge for subsequent layers—from water‑dilutable coatings and adhesives to leveling and repair compounds.
The primer is suitable for concrete, anhydrite, masonry, plasters, gypsum board, and fiber‑cement boards and other mineral substrates. The formulation contains surfactants, defoaming and preservative agents and does not contain heavy metals. The result is improved adhesion, lower consumption of subsequent materials, and a long‑term stable surface.
*Always verify suitability for specific conditions and follow the technical data sheet of both the substrate and the final layer.
