An advanced aqueous deep primer with both strengthening and hydrophobising properties, Remmers Primer Hydro HF is specially formulated to penetrate deeply into porous mineral substrates, consolidating and stabilizing the surface from within. Its water-repellent (hydrophobic) effect helps protect against moisture ingress while maintaining the substrate’s breathability, preventing issues such as frost damage, efflorescence, and mold growth. Ideal for use on exterior masonry, render, and concrete surfaces, this primer enhances adhesion for subsequent coatings and extends the lifespan of the entire coating system. Fast-absorbing and easy to apply, it’s a trusted choice for both renovation and new-build projects where long-term performance and protection are critical.
