How to Waterproof Wood
Waterproofing wood fences, decking and furniture is the best way to protect these wooden structures from moisture damage, rot, delamination and even biological growth such as algae, mould and fungi.
While there are home remedies that you can use to offer some protection, the most effective way to waterproof wood is to use a specialist wood sealer that provides a strong defence against moisture and contaminants.
How to Waterproof Wood with GK Invisible Wood Sealer
GK Invisible Wood Sealer is a water-based sealing solution that has been specially formulated to penetrate deep into wood, creating a robust defence against moisture and rot. This wood sealer is specifically designed for use with decking, fencing, timber and other wood structures. Its algae-repelling formula keeps your outdoor wooden structures and surfaces pristine all year round.
This breathable solution works by allowing water vapour to pass through, whilst preventing water from penetrating the wood. This protects the wood against rotting or delaminating.
GK Invisible Wood Sealer is both UVA resistant and highly resistant to any wear which prevents wood from greying and prevents scratches or chips.
How to Apply GK Invisible Wood Sealer
Apply with a brush, long pile roller, or low-pressure spray to saturation in an even coat.
Apply a second wet-on-wet coat before the first coat dries for deeper penetration.
Avoid runs, drips, or puddling. Remove excess product with a clean lint-free cloth.
Leave the sealer to dry.
Drying time: Touch dry within 2 hours, fully dry after 24 hours. For decking and flooring, allow 24 hours before heavy traffic.
How to Waterproof Wood with Home Remedies
While dedicated wood sealants and treatments offer the most reliable waterproofing, there are some "home remedy" approaches that can provide a degree of water resistance, though they may require more frequent reapplication and may not be suitable for all situations.
Waterproofing Wood with Natural Oils
Linseed oil and tung oil are traditional options. They penetrate the wood, offering some water repellency.
Danish oil is a blend of tung oil and varnish, providing slightly better protection.
Apply liberally, let it soak in, and wipe off the excess.
Limitations: Not ideal for light-coloured woods as they can yellow. They also require regular reapplication.
Home remedies generally offer less robust and long-lasting protection compared to commercial, specialised sealants. For more reliable and durable waterproofing, especially for outdoor wood surfaces and structures, it's recommended to use products specifically designed for that purpose.
Summary
The most effective way to waterproof wood is to use a specialised sealer like GK Invisible Wood Sealer. This water-based solution deeply penetrates the wood, providing a strong defence against moisture and rot.
GK Invisible Wood Sealer allows water vapour to escape while blocking water penetration to prevent rot and delamination. Additionally, it offers UVA resistance and wear protection, helping to prevent wood from greying, scratching, or chipping, and its algae-repelling formula keeps wood surfaces clean.
