TIMBERSEAL PS
TIMBERSEAL PS is a low viscosity, solvent free epoxy wood primer which penetrates into timber saturating it before curing. It’s primary use is as a primer under other coatings but it can also be used for the restoration of old timber by the resin impregnation technique, or in new construction as a pre-treatment for epoxy glued joints.

SUBSTRATE PREPARATION
Timber should preferably be clean and dry. TIMBERSEAL PS will adhere well to damp timber but a high moisture content will inhibit the product from soaking into the timber. Any grease or oil must be removed using a suitable solvent and any existing coatings should be either removed or sanded to provide a key.
APPLICATION CONDITIONS
TIMBERSEAL PS is a low viscosity coating so is easy to use even at lower temperatures. However epoxy coatings should not be applied in temperatures of less than 7°C or in very high humidity. MIXING TIMBERSEAL PS resin should be pre-mixed in the tin before the hardener is added, preferably with an electric mixer. After the hardener has been added to the tin mix for at least 2-3 minutes, pay particular attention to the sides and bottom corners of the tin to ensure that all materials are thoroughly incorporated. When mixed, the resin and hardener will start to react, generating heat. This will then accelerate the reaction. The greater the mass of epoxy, the more heat will be generated and the shorter the pot life. If you require a smaller quantity or are unable to use all of the material within its pot life, weigh out resin and hardener in the proportions specified on the label using digital kitchen scales.
APPLICATION
Timberseal PS should be applied liberally by brush, roller or spray. In order to saturate the wood with resin it should be reapplied as it soaks into the timber. The product will remain fluid on a timber surface for several hours once saturated.
OVER-COATING
Timberseal PS must be overcoated within the times shown in the table overleaf according to the ambient temperature. If it is allowed to cure beyond the maximum overcoating time, glossy areas must be abraded.
Advantages
- Low viscosity and slow cure promotes penetration into timber
- Natural tall (wood) oil in the hardener provides flexibility and
compatibility with timber. - Excellent adhesion to teak and even to damp wood, far greater than conventional primers.
- Economical, no more expensive than many conventional coatings.
