Maintenance

Choose KDAT for Maximum Stability

Always choose KDAT over wet brown framing. Kiln drying removes up to 80% moisture for a warp-resistant Missouri substructure.

Seal All End Cuts Immediately on Site

Apply end-cut preservative to every fresh cut before installation. This maintains full rot protection across all framing members.

Use Corrosion-Resistant Fasteners Throughout

Always use stainless steel or hot-dipped galvanized fasteners. Standard steel reacts with MCA treatment, causing rust and fastener failure.

Apply Deck Sealer Within Two Weeks

Seal KDAT framing within two weeks of installation. This locks in the brown finish and protects against Missouri's wet seasons.

Ensure Proper Substructure Ventilation

Keep joists at least 18 inches off the ground. Good airflow reduces moisture buildup and long-term rot risk beneath Missouri decks.
