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.

Can this wood be used for raised beds?

Asked by Terry March 26, 2016

nothing edible like vegetables, but for lush perennials, sunflowers and caladiums, cascading over sides...this wood lasts forever.

When can I paint this board? Paint type?

Asked by BCB March 11, 2016

If you desire to paint pressure-treated wood with an oil based paint, make sure the wood is dry before application. Pour some water over the surface. If it beads, wait until the board dries; if it is quickly absorbed into the wood, it's ready to be painted.
