LAVAFINISH FF is a single-component, polymer-modified cementitious fairing coat developed for producing smooth, fair-faced finishes over concrete. Formulated with high-performance cement, fume fillers, and advanced additives, it fills surface imperfections such as blowholes and pores in 0.5–3 mm layers. It requires only water addition on-site and can be applied on horizontal and vertical surfaces. Once cured, LAVAFINISH FF forms a shrinkage-compensated, crack-resistant, and impermeable layer that bonds excellently to concrete. It provides long-lasting resistance to atmospheric gases, chlorides, and salts, ensuring surface durability and aesthetic refinement for both new and repaired concrete structures.
