How to prep walls for painting
See the 331 Technical Data Sheet for full details, however in brief:
For previously painted walls
- Remove flaking and unstable paint. Fill any cracks with Auro 429 Natural Wall Filler and sand smooth.
- For surfaces that paint doesn't stick to easily and in situations where stains are coming through the walls, you might want to consider a using a Stain Block - either Auro 505 Fine Stain Block or Auro 506 Textured Stain Block.
For newly plastered walls
You can prime walls with:
- a "Mist" coat of this paint (Auro 331 diluted with a maximum of 10% water), or
- A Grip Coat of either Auro 505 Fine Stain Block or Auro 506 Textured Stain Block diluted by up to 10% or
- on highly or irregularly absorptive substrates we recommend priming with AURO 301 Natural Plaster Primer.
