Getting Started
Surface Preparation
How do I Prepare my Limewash ready for painting ?
Stir well -We recommend a machine stirrer, like a Bamix stick blender, or an egg whisk, not a stick.
Make sure all pigment is thoroughly mixed intothe paint.
Do not paint from a full bucket.
Decant into a larger vessel and work with only around 8cm (3in) of paint in a bucket.
Continue to stir paint regularly while painting.
How do I prepare my wall for Limewashing ?
Ensure your surface is correctly prepared based on your wall type, and whether it’s previously been painted.
Your walls may require an undercoat-sealer/primer as well as Bauwerk Prep Coat in order to create an ideal base for limewash paint.
How do I prepare a new or repaired Gyprock, Plasterboard, or Drywall ?
If your wall is already painted or are made of gyprock / drywall / plasterboard or plaster. It is very important that your walls are correctly primed, as Limewash and Prep Coat will not mask what is on your wall, for example, inconsistent materials like the join lines, may ghost through the final finish. The primer/sealer should have good masking capacity.
Step 1. We recommend 2 coats of a good quality undercoat/sealer primer -not a mist coat and non diluted
Step 2. Apply 1 of BAUWERK PREP COAT
Step 3. Apply 2 coats BAUWERK LIMEWASH
Note- You can skip Step 1. If your walls are already correctly primed and without patches and repairs
Do I need to use BAUWERK Prep Coat on my Gyprock, Plasterboard, or Drywall ?
We have especially developed our Prep Coat as a bridge coat between standard paint and primers to make limewash more durable, and easy to apply. BAUWERK 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.
Can I use Bauwerk Prep Coat on external walls ?
No, Prep Coat is only for use on internal walls
Do I need to use a primer or Bauwerk Prep Coat on external walls ?
No we don't recommend the use of primers and Prep Coat on natural exterior walls, like brick or render or stone, The is because Limewash
should be able to be absorbed into the natural materials becoming part of the wall.
What if my exterior brick or render wall is already painted or patchy ? Can I use Limewash ?
If your walls have been patched or repaired or has a mix of materials over the surface we recommend sealing over these areas with 2 coats of a water-based undercoat-sealer/primer. Sealing the wall ensures a consistent surface and prevents ghosting of patched areas coming through in the final finish.
On previously painted exterior surfaces, we recommend applying a coat of a thin acrylic render product - primer- before applying Limewash, this will provide an absorbent layer for the Limewash to adhere to on the wall. If Limewash is painted over a sealed or non-absorbent exterior wall exposed to the elements, you can anticipate a shorter maintenance period.
