Loctite Polyseamseal Rain Guard Washout Resistant Exterior Sealant
The Loctite Polyseamseal Rain Guard Washout Resistant Exterior Sealant is the top, completely non-toxic exterior sealant because for one, it is washout resistant. This is good if you’re working in an area prone to rain because an unexpected rain before the sealant is cured won’t rinse it off. It’s also paintable, which is great if you want a caulk that won’t affect the aesthetic value of the exterior of your home. Finally, it’s mildew and mold resistant, which is good because mildew and mold can yellow and stain the caulk with age.
