Before application, ensure the surface is clean, dry, and free from dust, grease, or loose particles. For cracks and defects, repair and level the area for better adhesion. Mix the putty well before use. Apply evenly with a putty knife or trowel in thin, uniform layers, allowing each coat to dry fully before applying the next. Sand lightly between coats for a perfectly smooth finish. Suitable for exterior masonry, plastered walls, and brickwork. Avoid application in damp or rainy conditions. Proper surface preparation and stepwise application ensure a durable, long-lasting base that improves paint performance.
