The Benefits
Creating problem-solving products that meet “real world” challenges, such as painting over water stains on internal walls and ceilings, Zinsser work with contractors to provide tried and tested solutions to painting problems.
Repairing and decorating after water damage can feel daunting but, with Zinsser, the process is straightforward, quick, and cost-effective. No need for expensive labour costs or lengthy disruption and downtime for businesses and services, landlords or homeowners, just a simple solution that can be completed in a day with excellent results.
Zinsser B-I-N primes and seals in one, blocking stains permanently and drying in as little as 45 minutes, whilst Zinsser Perma-White Interior is a durable finish coat that guarantees against mould and mildew for 5 years and is available with more than 4,000+ colours from RAL, NCS, and British Standard.
Step 1. Surface Preparation
The affected surface must be clean and dry, free from anything that could interfere or affect adhesion of Zinsser products or application of materials. Loose and failing material should be removed through scraping the area or brushing using a stiff-bristled brush, to a sound edge.
Use a fine grade abrasive paper to feather the sound edge.
Prior to painting, the moisture content should not exceed 18%.
Remove all dust and all visible signs of organic growth, treating affected areas, in accordance with the manufacturer’s instructions, with Zinsser Mould Killer & Remover.
Allow to dry; any areas with sound paint remaining should be washed down to remove contaminants with Zinsser Universal Cleaner & Degreaser, rinsing thoroughly with clean water to remove any remaining residues and allowing time to dry.
Cracks and small defects in the surface should be filled with a suitable filler (as appropriate in accordance with the manufacturer’s instructions), allowed to dry and then rubbed down with a fine-grade abrasive paper, removing all dust.
Step 2. Patch Priming & Bring Forward
Use Zinsser B-I-N Primer Sealer to patch-prime all bare and filled areas and surfaces in accordance with the manufacturer’s instructions, allowing a minimum drying time of 45 minutes (in normal conditions) before bring forward patch-primed areas with more Zinsser B-I-N Primer Sealer and allowing that to dry.
Step 3. Priming
All of the areas to be decorated should be primed with one full coat of Zinsser B-I-N Primer Sealer before allowing, in normal conditions, a minimum of 45 minutes to dry.
Step 4. Decoration
Two coats of Zinsser Perma-White Interior, available in Matt, Satin or Semi-Gloss finishes with over 4,000+ colours from RAL, NCS, and British Standard to pick from, can be used to decorate the prepared and primed areas in accordance with the manufacturer’s instructions, with a minimum drying time of two hours between coats.
