Undecorated surfaces can be stained through serious damage, such as leaking roofs, or simply splashed from nearby water sources such as taps and basins, spilled drinks, etc. Such surfaces could include:
- Worktops, benches and chairs
- Shelves and storage units
- Door and window frames
- Panelling on walls and ceilings
Water stains tend to reappear through freshly-painted surfaces if they are not properly blocked, causing more time and money spent stripping work back and starting again. Businesses and landlords could do without the hassle and downtime, so why not get it right first time with Zinsser?
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 undecorated water stained surfaces.
Step 1. Surface Preparation
Ensure surfaces are clean and dry, free from anything that could interfere with adhesion or application of the materials to be applied.
Loose material should be removed by scraping or brushing the surface with a stiff bristle brush to a sound edge.
Prior to painting, the moisture content should not exceed 12%.
Remove all dust and then remove all visible signs of organic growth, treating affected areas with Zinsser Mould Killer & Remover in accordance with the manufacturer’s instructions and allowing them to dry.
Fill any cracks and small surface defects with a suitable filler as appropriate, in accordance with the manufacturer’s instructions, allowing the surface to dry before rubbing down with a fine grade abrasive paper, and then removing all dust before priming.
Step 2. Priming
Use one full coat of Zinsser B-I-N to prime the surface that is to be decorated, in accordance with manufacturer’s instructions, allowing a minimum of 45 minutes drying time in normal drying conditions before decorating.
Step 3. Decoration
The surface can now be decorated in one of more than 350 colours, in matt, satin or semi-gloss finishes, with two full coats of Zinsser Perma-White Interior, allowing a minimum drying time of two hours between coats in accordance with the manufacturer’s instructions.
