What resin is best for sealing concrete versus wood?

Selecting the Right Resin for Each Surface

Concrete and wood have distinctly different characteristics, which call for tailored resin solutions. For absorbent concrete floors and driveways, a single-component methacrylic resin, such as Resinstone, offers deep penetration and a strong, waterproof seal while remaining breathable to prevent trapped moisture. Timber, on the other hand, benefits most from a specialised epoxy formulated for wood, like EpoxyWood. Its ultra-low viscosity allows it to soak into wood pores, reinforcing the structure and providing lasting waterproof protection.

Practical Tips for Application

• Surface Preparation: Ensure concrete is clean, dry, and free from dust or oils before applying methacrylic resin. Wood should be thoroughly dry and lightly sanded to maximise adhesion of epoxy resins.
• Application Methods: Methacrylic resin is often applied by roller, brush, or airless spray for even coverage on concrete. Epoxy resins for wood can be spread with a brush or poured and worked into the timber for deeper reinforcement.
• Drying and Curing: Allow ample time for the applied resin to cure before exposing the surface to traffic or moisture. Always follow the product’s guidance for best results.

When It Matters Most

Choosing the right resin matters when you need robust, long-term protection against water ingress, weathering, and routine wear. Outdoor driveways, garage floors, and boat decks are examples where this choice is essential for both safety and preservation.
