MicroPro® Care and Maintenance

Apply a weather-resistant finish - Any exposed lumber, pressure treated or not, should be protected with a high quality water repellent finish or stain with water repellent to help reduce warping, checking, and splitting.
If you desire to apply a paint, stain, clear water repellent, or other finish to your preservative treated wood, we recommend following the manufacturer’s instructions and label of the finishing product. Before you start, we recommend you apply the finishing product to a small exposed test area before finishing the entire project to insure it provides the intended result before proceeding.

Drill pilot holes - Drill pilot holes, especially when nailing or screwing near the edge or end of a board. Pilot holes will help minimize splitting.

Deck board spacing - During construction, should the lumber become wet, butt deck boards together. As drying occurs, some shrinkage can be expected. If the wood is dry, allowing for shrinkage is not necessary.

When appearance permits, attach boards bark side up - As a general rule, attach boards bark side up (annual rings arc upward) to reduce cupping; however, the best face should be placed up when a defect of the wood is apparent. Fasten thin boards to thicker boards to maintain structural integrity.
