How To Paint Surfaces Exposed To High Humidity

Follow our 4-step guide below for quick and cost-effective painting of surfaces subject to high humidity, using hygiene coatings such as Zinsser products for properly prepared and quickly finished decoration in areas such as bathrooms, kitchens, changing rooms at swimming pools, etc.

High humidity environments are tough on painted surfaces with water vapour in the air and splashes often causing paint to peel. Such imperfections can help provide a warm and moist place for fungus to grow, which can be a health risk as well as unsightly on walls and ceilings.

Step 1. Surface Preparation

Before starting, ensure that surfaces are clean and dry; the surface should be free from anything that could affect and interfere with the adhesion of Zinsser products and materials that will be applied.

Loose material should be removed by scraping or brushing, using a stuff-bristled brush to a sound edge.

Prior to painting, the moisture content should not exceed 12%.

All visible signs of organic growth should be removed, with the affected areas treated with Zinsser Mould Killer & Remover, in accordance with the manufacturer’s instructions, and the area allowed enough time to dry.

Step 2. Cracks and Surface Defects

Use a suitable filler, as appropriate in accordance with the manufacturer’s instructions, to fill any cracks and small surface defects, and allow it to dry before rubbing the surface down with a fine grade abrasive paper.

Remove all dust and move on to step 3 below.

Step 3. Priming

Prime all over the surface with one full coat of Zinsser Bulls Eye 1-2-3, in accordance with manufacturer’s instructions.

Bulls Eye 1-2-3 Primer offers fast drying times, touch dry in 30 minutes and able to be recoated after just an hour.

Step 4. Decoration

Now that the surface has been suitably prepared and primed, decorate with two full coats of Zinsser Perma-White Interior in accordance with the manufacturer’s instructions, allowing a minimum drying time of 2 hours between coats (in normal drying conditions).

Available in Matt, Satin or Semi-Gloss finishes, Perma-White Interior Paint has over 350+ RAL and BS colours to pick from.
