Drywall + Plasterboard
the 3P Rule explained: how to easily lime wash drywall and plaster board panels
How can I apply lime wash paint on top of plaster board or dry wall panels?
My wall is already painted or my walls are made of gyprock / drywall / plasterboard or plaster:
It is very important that your walls are correctly primed to avoid any spot repairs or surface inconsistencies ''ghosting'' through the finish paint work.
Neither Limewash paint , nor BAUWERK Colour Prep Coat have the ability to hide repairs or differences in surface absorbency.
You need to apply a suitable PRIMER to ensure that will, for example, inconsistent materials like the joint lines between drywall panelling do not ghost through the final finish.
Step 1. Primer
After all repairs and filling is finished we recommend to prime the your surface with a locally available good quality, water based, acrylic undercoat/sealer primer -not a mist coat and non diluted. Follow the manufacturers application advice, but apply at least two coats.
Step 2. Prep-Coat
Apply 1 of BAUWERK Colour PREP COAT. To see how that is done click here.
Step 3. Paint
Apply 2 coats BAUWERK Colour LIMEWASH. To see how that is done click here.
Note👍 - You can skip Step 1. If your walls are already correctly primed and without patches and repairs
Why do I need the BAUWERK Colour PREP COAT after I applied a Primer?
BAUWERK Colour Prep Coat is not a primer. It is important to understand that BAUWERK Limewash and Prep Coat have no capacity to mask what is on your wall, it allows all the history and the materials of the wall to come through.
Lime wash paint always needs a moderately absorbent surface for easy application and durability. Our Prep Coat functions as a bridge coat between standard paint and/or primers. It allows Bauwerk Colour limewash paint to be absorbed and bond with your wall surface.
Note👍 - If you are painting a lime or cement based render, or bricks that have not previously painted you can apply the paint direct without the need for primers or Prep Coat (see our full descriptions for render and brick painting with lime wash paint).
