Applying a saturation coat of polyester resin to wood involves preparing the surface and properly mixing the resin as specified for this type of application. Based on the provided information for applying a wood saturation coat of resin, the process focuses on surface preparation and resin mixture.
Here are the steps involved in applying a saturation coat of polyester resin to wood, according to the reference:
Surface Preparation
The first crucial step is to prepare the wood surface to ensure proper adhesion of the resin.
- Sand the surface: Use 60 or 80 grit sandpaper. This step is essential to rough up the surface, creating a mechanical key that allows the resin to grip the wood fibers effectively.
Resin Mixing
Once the surface is prepared, the polyester resin needs to be catalyzed and thinned correctly for a saturation coat.
- Catalyze Polyester or Vinylester: Mix the resin according to the manufacturer's instructions, specifically catalyzing it. Catalyzing involves adding the appropriate hardener to initiate the curing process.
- Thin the resin: After catalyzing, thin the mixture 25% with acetone. This thinning step reduces the resin's viscosity, allowing it to penetrate the wood surface more deeply, which is characteristic of a saturation coat.
Following these steps prepares the wood and the polyester resin mixture for application as a saturation coat, based on the provided reference.
