Preventative Maintenance Plan

1. Depending on the location of your outdoor project with regard to direct sun exposure, foliage coverage, etc., it may be sufficient to clean/brighten and recoat every two years. 2. If you decide to wait two or more years to perform your next cleaning/brightening, you may want to use a power washer. Be sure that the cleaner/brightener you use contains a mildewcide.

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

Treated balusters are used not only for safety and strength, but they also aid in creating a custom look to your railing project.

Pressure-treated timbers are treated for protection against termites and rot. Ideal for a variety of applications including decks, play sets, walkways and landscaping projects where lumber is exposed to the elements. When used properly, it is both safe and environmentally friendly.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.
  • Made of pine
  • For use at ground contact
  • Significantly improved corrosion resistance for metal fasteners
  • Lifetime limited residential warranty

            New mailbox
            Used this 4 x 4 to install a new mailbox. It was 6 ft in length. I dug a 3 ft hole for the post leaving 3 ft which the new mailbox fit on perfectly. The whole project took less than 1 hr.
