STAINBLOCK - undercoat for "difficult" stains & bare ferrous interior metals.

ECOS stain blocking primer is highly effective for concealing and blocking out difficult stains such as rusted metal, rust staining, tannins from hardwoods (oak, mahogany, etc.), water stains on (for example) plaster walls and ceilings from leaking gutters, cisterns, roofs, etc. and many other "difficult to get rid of" stains. As a result, when appropriately applied to a surface, this primer will increase a surface's durability. ECOS primer also does not have the harsh odors common in other high performing primers. To achieve the best results, choose ECOS stain blocking primer for your next project.

*NOTE- Will not block oily/tarry stains such as asphalt or those from coal fires. Not ideal for some types of cast iron - please ask for advice. Not for aviaries, aquaria, reptiles.

Product Label
Preparation Surfaces should be clean, dry, sound, and free from dirt, dust, grease, and loose or flaking material. Clean stubborn areas with mild detergent. Rinse and dry thoroughly before painting. Soft or crumbly substrates should be pre-treated.
Application and Clean Up Under most conditions thinning is not necessary. Stir gently before and during use. Intermix if using multiple containers to ensure color uniformity. Generally only requires one coat. Sand lightly between coats as this product may raise the grain of the wood. Normally dries to the touch in one hour. Allow four hours before sanding or painting. Can be applied using a good quality synthetic brush; or rolled using a shed resistant 1/4"-3/8" roller cover. Avoid applying below 50oF.
