Painting plastic and uPVC surfaces require the use of a primer with outstanding adhesion to properly prepare for a top coat, otherwise paint will simply peel away to leave an unsightly surface that will need to be cleaned down and re-painted.
Time and money most can ill-afford.
Most plastic and uPVC surfaces found at businesses and in homes will be doors and windows. These can discolour over time with exposure to the weather and UV light, stain, or may need updating with a new colour scheme applied to the rest of the building exterior.
Conduits and pipes running along the tops of skirting boards and down walls from ceilings carry wires and pipes and can contrast against colour schemes; covering these with a matching colour to existing décor helps them blend in more.
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 plastic and uPVC windows and doors.
Step 1. Surface Preparation
The surface must be clean, dry and free from anything that will interfere with the adhesion or application of the products and materials to be applied.
Start by removing loose and failing material by scraping or brushing with a stiff bristle brush to a sound edge, feathering sound edges with a fine grade abrasive paper.
Remove all visible signs of organic growth from the surface, treating with Zinsser Mould Killer & Remover in accordance with the manufacturer’s instructions, and allow to dry.
Step 2. Priming
Remove contaminants and anything else that could interfere with adhesion, degreasing the surface overall with methylated spirits and frequently changing the cloth.
Use one full coat of Zinsser Bulls Eye 1-2-3 to prime overall, in accordance with the manufacturer’s instructions, allowing an hour’s drying time minimum (in normal drying conditions).
Step 3. Decoration
Interior projects – use two full coats, in accordance with the manufacturer’s instructions, of Zinsser Perma-White Interior in one of more than 350 colours in matt, satin or gloss finishes, allowing two hours minimum between coats for drying.
For exterior projects, decorate the prepared and primed surface with two full coats of Zinsser Allcoat Exterior Satin & Gloss in accordance with the manufacturer’s instructions, and allow a minimum drying time of one hour between coats.
