How to use this product

  • Wear rubber or plastic gloves when handling fibreglass
  • Surface Preparation Surfaces should be clean and dry and free from paint, grease and rust. Cut the fibreglass mat to shape, allowing approximately 3cm overlap all round. Tease out the fibres along the edge of the mat to give a feathered edge.
  • For wide holes, glue a piece of cardboard to the back of the hole to form a base.
  • Mixing: For each tablespoon of resin, squeeze 5 drops of hardener from the small tube and mix together thoroughly.
  • Do not prepare the mixture until required as only a limited time (20 minutes at 20°C) is available before the product gels.
  • Application Position the mat and apply resin/hardener mixture with a clean, dry brush. Be sure to impregnate the mat completely, working out all air bubbles. Add more mat and resin/hardener mixture to build up or contour the patch as required.
  • Finishing When the patch has completely hardened, (approximatly 1-2 hours, depending on the temperature), it can be sanded to a smooth finish. Fill imperfections with more resin. Paint if required.
  • Clean up product with Solvent Acetone before it cures

Handy tips

  • At higher temperatures, the working time decreases.
  • Can only be tinted with iron oxide or other dry pigment .which must be mixed in very thoroughly.
  • Surfaces to be joined should be clean and dry.
  • If recommended amounts of hardener are not used, cure time will vary or an incomplete cure may result.
  • A useful solvent to clean up epoxy and polyester resins BEFORE they are cured can be prepared by mixing 2 parts toluene with 1 part alcohol (eg methylated spirits or denatured alcohol).
  • In large amounts heat can be generated during cure. Care should be taken on heat sensitive surfaces with large amounts.
  • Use recommended levels of hardener and resin; variation may result in incomplete cure and variations in cure time.
  • Keep a canister of SELLEYS Sugar Soap Wipes nearby for a quick and effective cleanup.
