Protecting internal and external masonry structures in Rajkot from dampness, flaking paint, and persistent white salt deposits (efflorescence) requires a deep-penetrating surface pre-coat engineered for harsh environmental stress. UN1ON Prime is a premium water-dilutable, brush-applied wall sealing coating designed as a surface stabilizer and high-performance base primer for concrete and plastered surfaces. Engineered with German technology precision, UN1ON Prime penetrates porous plaster to bind loose particles, improve impermeability, and block alkali salts before topcoat paints are applied. Unlike non-porous sealers that trap moisture within the wall structure, its formulation allows the substrate to breathe while blocking external liquid ingress, preventing paint peeling and blistering. Trusted by painters, plaster contractors, and civil engineers across Rajkot, UN1ON Prime dries to a durable foundation in 4 to 6 hours, ensuring superior paint adhesion, extended finish life, and long-term protection against wall dampness.
