Setup, Compatibility & Care
Preparation: Ensure the area to be filled is clean, dry, and free of loose material. For repairs on decayed or rotten wood, use Polycell Polyfilla for Wood Hardener according to its instructions before applying the filler. This product is suitable for all interior and exterior wood repairs, especially for damage deeper than 5mm and for wood affected by decay or wet rot. It is ideal for windows, frames, sills, doors, floors, joinery, and garden furniture. Do not use in permanently wet or underwater conditions, or for filling gaps between floorboards.
Mixing and Application: Mix an equal amount from each component tub (Tub A and Tub B) until a uniform colour is achieved. Prepare only what can be used within 10 minutes. Press the filler firmly into the repair area and smooth with a filling knife.
Working and Finishing: After about 30 minutes, the filler can be carved or shaped. Sanding, planing, or filing can commence around 45 minutes after application. The filler can be painted, stained, or varnished in under 1 hour. Note that the filler's appearance after staining or varnishing may differ from the original wood; testing on a small, inconspicuous area is recommended. Do not use with wood dye.
Tool Cleaning: Remove excess product from tools before cleaning them in warm water. Dispose of any mixed, unused filler as per local regulations.
Storage: Do not use or store in extreme temperatures, and protect from frost.
