Flood knows the importance of having the right instructions on how to finish a deck, fence, weatherboards or other exterior wood surfaces. After properly preparing the wood with a Flood prep product, apply a Flood finish to protect and preserve your exterior wood surface while also beautifying it. Flood finishes have superior penetration and adhesion, and guard against damage caused by sun and moisture.
Before you start
WARNING! If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear an approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop. Before you start, find out how to protect yourself and your family by contacting the relevant authorities.
TIP: Finishing New Wood surfaces have a hard, shiny surface called mill glaze that prevents maximum penetration and bonding of a finish. To properly prepare the surface for application of a deck, fence or wall stain, treat with a solution of Flood Powerlift. To determine whether surface can be finished, test wood for absorbency by sprinkling water on the surface. If water is absorbed rapidly, the surface is ready for finishing.
