The Benefits

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 powder coatings.

Conventional paints won’t adhere to surfaces covered with a powder coating, and removing them requires strong solvents, abrasive blasting, or burning off the coating – all time and money that could be better spent elsewhere when opening a new businesses premises, or redecorating a property for sale or the rental market.

Luckily, Zinsser have developed products that are cost-effective and quick to apply and dry, simply painting over a suitably prepared powder coating to seal and prime the surface before finishing from a selection of 350+ colours.

Step 1. Surface Preparation

Clean down the surface and ensure it is dry and free from anything that could interfere or affect adhesion of Zinsser products and materials to be applied. Remove loose and failing material from the surface through scraping or brushing, using a stiff-bristled brush, to a sound edge before feathering with a fine-grade abrasive paper.

Remove all visible signs of organic growth and use Zinsser Mould Killer & Remover, in accordance with the manufacturer’s instructions, to treat the affected areas and allow to dry.

If any sound paint remains, clean the area down with Zinsser Universal Degreaser & Cleaner to remove any remaining contaminants and rinse with clean water thoroughly before allowing the surface to dry.

Step 2. Priming

Prime all over with one full coat of Zinsser Bulls Eye 1-2-3 Primer Sealer in accordance with the manufacturer’s instructions, allowing a minimum 1 hour drying time (in normal drying conditions).

Step 3. Decoration

For decorating interior surfaces, use two full coats of Zinsser Perma-White Interior Matt, Satin or Semi-Gloss, in accordance with the manufacturer’s instructions, with a minimum of two hours drying time between coats.

On exterior projects, Zinsser AllCoat Exterior Satin or Gloss can be used to decorate in accordance with the manufacturer’s instructions, allowing a minimum drying time of 1 hour between coats.

Both Perma-White Interior and Allcoat Exterior are ultimate performance paints providing up to 15 years of protection to surfaces, and are available more than 350 colours from RAL and & BS.
