See the Coating Workflow in Action

Visualise each stage of coating a wood panel with fibreglass resin – from preparing the raw timber and laying out the fibreglass mat, to saturating with resin and achieving a bubble-free finish.

Step 1: Prepare the Wood Surface

Start by thoroughly cleaning the wood panel to remove all dust, grease, and loose fibres. Sand the surface evenly using 80–120 grit sandpaper to roughen the texture — this helps the resin mechanically grip the wood fibres. After sanding, wipe down the entire panel with acetone or a suitable degreaser to remove any lingering contaminants. Make sure the panel is bone dry; excess moisture can cause the resin to foam or not cure properly.

Proper surface preparation is critical for resin adhesion; do not rush this stage or skip drying the surface completely.

Step 3: Apply Fibreglass Mat and Resin

Cut your fibreglass mat to size so it slightly overlaps the panel edges. Lay the mat dry onto the primed surface. Mix your chosen resin by following the product’s instructions — “Carbon Resin” – Epoxy Resin for Carbon Fiber & Fiberglass Coating is recommended for best transparency and ease of application with technical fabrics, or select the Resin Fibreglass Repair Kit for polyester resin reinforcement.

Pour or brush resin onto the mat, gently working it in with a squeegee or roller until the fibres are fully saturated and transparent. Repeat until all layers are coated. Apply the fibreglass resin and mat carefully for optimal impregnation and a tough finish that resists delamination.

Step 5: Allow to Cure and Sand if Desired

Let the coated panel cure fully as per the resin instructions; avoid moving, pressing, or recoating until it feels hard and dry to the touch. After full curing, you can sand rough areas with fine-grit sandpaper and, optionally, apply a further thin coat of resin for a glossy, glass-like finish. Always wear protection when sanding cured resin to avoid inhaling dust material.

Curing time affects strength and clarity of the finish — patience here yields a premium, professional outcome.
