Choosing The Right Stain Or Paint

When determining the right stain and paint for your deck, consider what color will best enhance the wood's finish.

Paint or Stain Tips

If you desire to paint or stain the treated wood project, it is important that the wood be dry enough to accept a coating. The best way to determine if the wood is sufficiently dry to paint or stain is to sprinkle droplets of water onto the wood. If the water droplets are absorbed, the wood is ready to be painted or stained. If the water droplets bead on the surface of the wood, it is too wet. You should wait a few days before attempting to paint and stain the wood.

Balusters & Spindles

Pressure-treated timbers are treated for protection against termites and rot. Ideal for a variety of applications including decks, play sets, landscaping and other outdoor projects where lumber is exposed to the elements. This timber can also be painted or stained. When used properly it is both safe and environmentally safe.Treated wood is typically still wet when it's delivered to The Home Depot or job site. As it dries, you should expect slight changes in width and length. As lumber dries, it may split, cup and warp. This is more likely to occur to occur in lower-grade boards, where knots and uneven grains are already present. Each piece of lumber is unique and carries physical characteristics that may include the following: knots, warping, shrinkage, swelling and/or splitting.

The delivery service sent out probably the worst 6 4x4x16 boards they could find. I was very disappointed, inside the store they had much better quality but they just picked probably the top junky ones full of nots and bowed and sent them to me. Which they were exposed I knew better but I was hoping they would send out quality material especially at an $80 delivery fee won’t ever do that again! You lost a customer!!
