Getting Started
To achieve your desired limewashed look, it is important to know that the success of your overall project may come down to the preparation of your wall surface.
Missing or rushing steps in the beginning won’t always save you time and money, and opting for cheaper tools and materials may cost more in the long run. You may also find the limewash harder to apply or experience issues such as ghosting or a patchy finish.
Whether your wall requires a primer, Bauwerk Prep Coat or simply a good clean will be determined by the make up of the wall surface you will be painting and if your wall is inside or on the exterior of a building.
Please see our Surface Guides for more detail on how to prepare your particular wall surface for lime washing.

How do I prepare my wall for Limewashing ?
IEnsure 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.
You can find detailed instructions for your specific surface in our Surface Guide section
Internal Wall Preparation
How do I prepare my new or repaired Plasterboard or Plaster wall ?
If your wall is already painted or made of gyprock, drywall, plasterboard, or plaster, it’s important to follow the 3xPs of Preparation: Prime, Prep, and Paint. Proper priming ensures even absorption of limewash paint.
Limewash and Prep Coat will not mask what is already on your wall, so your primer/sealer should have good masking capacity. Otherwise, inconsistencies like join lines may ghost through the final finish.
For new plasterboard walls, priming prevents the join compound from showing as visible lines. On old, previously painted, or repaired walls, it helps prevent patchy areas or material inconsistencies from affecting the final look.
Surface Preparation
Step 1 : Prime We recommend 2 coats of a water-based undercoat-sealer/primer –not a mist coat and non-diluted. You do not need to prime if your walls are already correctly primed and without patches and repairs
Step 2: Prep Coat Apply 1 coat of Bauwerk Prep Coat.
Step 3: Paint Apply 2 Coats of Bauwerk Limewash Paint
Do I need to use Bauwerk Prep Coat on my new or repaired Plasterboard or Plaster wall ?
We have specially 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.

External Wall Preparation
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. This is because Limewash paint 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 Paint?
On previously painted exterior surfaces, we recommend applying a coat of a thin acrylic render product/Acratex 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.
