When a wood surface needs to be re-coated, it should be repaired, sanded and cleaned so the new stain can fully penetrate the surface of the wood for maximum durability of the finish. After the wood is prepared, new stain can be applied. This coating will help protect the wood from sun damage. Paint on the other hand, will completely block the sun but it can also trap moisture which encourages faster decay of the wood. It’s important to use the correct type of applicator and the correct application technique to ensure the coating is evenly distributed and provides maximum protection for the wood. For example, a roller-applied stain must first be worked into the wood with a brush to give a more uniform colour and deeper stain penetration. Most stain manufacturers provide detailed brochures that discuss stain product options, surface preparation and application tools and techniques. It’s important to use the correct type of applicator and the correct application technique to ensure the coating is evenly distributed and provides maximum protection for the wood.
