Can you paint over limewash and distemper? Our 4-step guide will show you how to prepare, prime and decorate interior limewash and distemper walls (usually found in traditional, heritage buildings) in more than 350 colours using Zinsser products.
Limewash and distemper are often found in traditional heritage buildings, being vapour permeable and allowing a building to “breathe”. These highly porous substrates create a host of painting challenges, which our guide below will show you how to overcome on interior projects with Zinsser products.
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 limewash and distemper.
Step 1. Surface Preparation
Limewash and distemper surfaces must be clean and dry, free from anything that will interfere or affect with the adhesion and application of Zinsser products and materials to be applied.
Scrape and brush the surface to a sound edge using a stiff-bristled brush, removing all loose and failing material.
Prior to painting, the moisture content should not exceed 18%.
Remove all visible signs of organic growth and treat the areas with Zinsser Mould Killer & Remover in accordance with the manufacturer’s instructions, allowing the surface to dry.
Fill any cracks and small surface defects using a suitable filler, as appropriate in accordance with the manufacturer’s instructions, allow it to dry and then rub down with a fine grade abrasive paper and remove all dust.
Step 2. Patch Priming & Bring Forward
Use one coat of Zinsser Grade 1 to patch prime all bare and filled areas (in accordance with the manufacturer’s instructions), allowing a minimum drying time of 2 hours in normal drying conditions, and then bring forward the patch primed areas with another coat of Zinsser Grade 1.
Step 3. Priming
Once dry, prime all limewash and distemper areas to be decorated with one full coat of Zinsser Grade 1.
Step 4. Decoration
Decorate the surface with one or two coats of Zinsser Grade 1 in accordance with the manufacturer’s instructions.
A high-performance paint for the interior decoration of walls and ceilings in traditional and historic buildings, including churches, castles and period properties, Zinsser Grade 1 has a matt finish and is available in more than 60 colours from RAL and BS shades.
