| 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 four hours. Allow twenty-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 50°F (10°C). |
