Introduction
Did you know that one small overlooked detail can ruin your outdoor furniture or decking? It all comes down to sealing every surface, especially those hidden spots like the end grain and the undersides of furniture legs. Without proper sealing, water can sneak in, causing peeling, rot, and expensive repairs. Here’s how to paint and seal outdoor furniture and decking correctly the first time.
Outdoor Furniture: Sealing Every Inch
Outdoor furniture is constantly exposed to rain, humidity, and fluctuating temperatures, so ensuring it’s completely sealed is critical.
Focus on End Grain
The end grain of wood—where the wood is cut—is the most absorbent part and a major weak spot for water entry. Even if the main surfaces are sealed, untreated end grain can absorb water, causing swelling and peeling. Ensure you seal the end grain thoroughly with the recommended number of coats.
Don’t Forget the Underside
The underside of legs is another often-missed area. When these sit in water, capillary action allows moisture to creep up, leading to peeling sealer and exposing bare wood to damage.
Top Tip: After sealing, attach plastic furniture feet nails to the bottom of the legs. This raises the furniture slightly off the ground, preventing the legs from sitting in water when it rains.
Choose the Right Sealer: Use Harlequin Exterior Sealer for maximum protection. Available in gloss and matte finishes, it’s designed to shield against water, UV rays, and wear.
Decking: Pre-Treatment Is Key
Decking is another area where preparation is everything. Neglecting the sides, underside, or end grain of wooden slats can lead to rot over time, especially when water stagnates.
Seal All Sides Before Installation
Before installing decking boards, make sure all surfaces—top, sides, underside, and especially the end grain—are sealed. Once the boards are installed, the underside and edges are usually inaccessible, leaving them vulnerable to water damage.
Recoat After Cutting to Fit
Even if you pre-treat the planks, any cuts made during installation expose fresh wood. These areas must be re-sealed with the recommended number of coats to maintain full protection.
