Nippon Weatherbond Exterior Putty

Nippon Paint Weatherbond Exterior Putty is an ultra-premium water-based acrylic filler specially designed to smooth, level, and prepare exterior masonry surfaces before painting. Unlike standard interior fillers, it features a durable structural formulation that can withstand outdoor conditions, including rainfall, temperature changes, and sunlight exposure. Its flexible and weather-resistant composition helps prevent shrinking, cracking, and surface damage while maintaining a strong bond with exterior concrete, brickwork, cement plaster, and prefabricated outdoor surfaces. The high-density formula effectively fills deep cracks, surface imperfections, plaster gaps, and uneven areas to create a smooth and uniform base for topcoats. It also provides excellent alkaline resistance, helping protect finishing paints from damage caused by salt migration from concrete surfaces. The eco-conscious formulation is free from harmful heavy metals such as lead, mercury, chromium, and cadmium compounds, making it a safer choice for exterior applications. For best results, surfaces should be properly cured, cleaned, and prepared before application. After drying and sanding the filled areas smoothly, a suitable primer should be applied before finishing with premium exterior weather-resistant paints to achieve a durable and professional finish.
