Timber Water Repellent

Waterproof Timber Sealer

Differing from the traditional timber stains or coatings, Tech-Dry® Timber Water Repellent Spray is a water-based penetrating silicone sealer which saturates into the timber grains for water resistant timber. There is no peeling after the timber waterproofing products are applied.

At Tech-Dry, we’re proud to deliver water repellent solutions that can improve the longevity of outdoor timber furniture. Our waterproof timber sealer can significantly reduce water absorption of timber, which is responsible for the bulk deterioration of outdoor timber. The life of the resulting waterproof timber is significantly extended.

Tech-Dry® Timber Water Repellent Spray isn’t just a waterproof wood sealer. It may also be used to treat other neutral substrates such as fabric, paper, permeable natural stones and porous renders.

How to Waterproof Timber

For waterproofing timber, Tech-Dry® Timber Water Repellent can be applied using a brush, roller or spray. However, the product is preferably applied using a hand pressure spray or airless spray equipment to avoid direct contact of application equipment with the surface. This ensures a better result when waterproofing timber while also reducing mess.
