How should I prepare surfaces before applying antifosphate resin?

Cleaning and Drying the Surface

Begin by thoroughly cleaning the area to remove dirt, grease, or previous finishes. Use a suitable cleaner, ensuring no residue remains. Once clean, allow the surface to dry completely; moisture can interfere with the resin’s ability to bond and cure correctly.

Sanding and Dust Removal

Lightly sand the substrate to remove any glossy coatings or unevenness, aiming for a smooth, slightly roughened finish. This step creates a profile that helps the resin grip the surface. After sanding, meticulously clear away all dust—especially from grooves and corners—using a vacuum or a tack cloth.

For natural wood, consider applying EpoxyWood before your antifosphate resin to further stabilise and reinforce porous surfaces.

When Surface Prep Matters Most

Good preparation is crucial when restoring older materials, treating damp-prone wood, or working on decorative elements where finish quality counts. Taking time at this stage avoids future peeling, soft spots, or dull patches.
