Exterior Alkali Resistant Sealer Primer
Exterior walls are constantly exposed to wind, sun, rain, snow, and drastic temperature and humidity changes. Problems such as efflorescence, water seepage, and chalking in the substrate can easily lead to paint peeling, discoloration, and cracking, severely affecting the building’s appearance and durability. This exterior wall alkali-resistant sealing primer integrates multiple core functions, including alkali resistance, waterproofing and breathability, substrate reinforcement, and weather resistance and stain resistance. It creates an indestructible base layer protection for exterior walls, ensuring the building facade remains beautiful and resists the erosion of time.
