Fibreglass can be tough to paint over as it needs to be suitably prepared and primed for topcoats to properly adhere and stick to the surface. Zinsser’s Bulls Eye 1-2-3 is ideal for priming fibreglass as it provides a perfect key for topcoats.
Zinsser listens to contactors and develops new products – or adds features to existing products – to meet their changing needs, delivering world class products that meet “real world” challenges, providing tried and tested solutions to painting problems, such as painting over fibreglass.
Step 1. Surface Preparation
Prepare surfaces by ensuring they are clean and dry, free from anything that can interfere with the application or adhesion of materials and Zinsser products to be applied, removing loose and failing material by scraping or brushing with a stiff bristle brush to a sound edge.
Feather the sound edges with a fine grade abrasive paper, removing all visible signs of organic growth and using Zinsser Mould Killer & Remover to treat areas (in accordance with the manufacturer’s instructions) before allowing them to dry.
Step 2. Priming
Use methylated spirit to ensure the surface is free from any contaminants and anything that could interfere with adhesion, frequently changing the cloth, before priming overall with one full coat of Zinsser Bulls Eye 1-2-3.
Step 3. Decoration
Decorate interior surfaces with two full coats of Zinsser Perma-White Interior, in accordance with the manufacturer’s instructions, and allow a minimum drying time of two hours between coats.
Zinsser Perma-White Interior is available in Matt, Satin and Semi-Gloss finishes with over 350 colours in RAL and BS shades to choose from.
For exterior projects, decorate with two full coats of Zinsser AllCoat Exterior in accordance with the manufacturer’s instructions. Allow a minimum drying time of one hour between coats.
