MAINTENANCE - Lime Plaster, Lime Paint and Tadelakt
General Lime Plaster and Lime Paint Maintenance Interior plaster or lime paint maintenance requires little effort. The finish should last as long as the substrate. Our materials will not fade under normal conditions. Our materials will improve with time in durability and even color richness. Most cleaning and maintenance can be done with a water and a sponge. Mineral Sealer, if used, can be reapplied in high traffic areas if needed.
Exterior plaster or lime paint maintenance is similar to interior maintenance in that most dirt can be removed with water and sponge. Vasari Mineral Sealer protects lime finishes from stains and patina caused by heavy water contact. Re-apply Vasari Mineral Sealer if needed.
Shower waterproofing requires Mineral Sealer and additional Vasari Wax. To maintain the shower walls from potential patina discoloration, re-apply wax if water penetration appears in any area. Waxed shower walls can be cleaned with water and / or soap.
Cleaning: If Lime Paint, Carrera, Marmorino, Mastercoat or Veneziano is unsealed without Vasari Mineral Sealer and gets dirty, first use:
- A rag and water. Gently rub out the dirt. If that doesn’t work, use:
- 400 grit sandpaper over the blemish, then 600 grit to polish out, or;
- Wet the area and gently scrub with a fine sanding sponge
- If an oily spot is stubborn to water or abrasives, use clear spirits, like lacquer thinner, acetone or even nail polish remover.
- If all else fails, add water to the same color plaster as used on the wall, making a slurry or paint out of it, then dab the troubled area with slurry. Always use white cotton to clean; otherwise colored fabrics can bleed onto the plaster. If the plaster is sealed with Vasari Mineral Sealer, wax or other
sealers, use that product to try to clean the wall. If that doesn’t work, try the same methods as listed above for unsealed plaster, then be sure to reseal the plaster with the same product.
If cleaning acrylic sealed plaster, use the same methods (with the exception of cleaning it with acrylic sealer), then reseal the spot if it had to be sanded. If cleaning Lime Paint, clean with the same methods as above. If all else fails, dab it with the same color of Lime Paint, and after if necessary.
Patches, dings, nicks and holes: Clean the area around the hole. In some cases, sand the area around it, remove any waxes with solvent, and gently rub out any other water-soluble sealers. After cleaning, mask the area around it.
- If you have a nail hole, use the same material for the filler. If there is excess plaster, wipe with a damp rag. Fill the hole or scratch with the same plaster or lime paint was used on the wall. This might have to be filled more than once to make sure that it is flush with the rest of the wall. After the patch is dry, remove the masking, and gently dry or wet sand in the area to feather into the adjacent area.
- If you have a hole larger than 1” x 1”, use gypsum compound or drywall mud. You might have to fill the patch a few times with gypsum compound to make sure it’s flush with the wall. On the last layer, take a damp cloth and remove any excess plaster around the patch. Allow 24 hours to dry, sand it and prime if necessary. Re-apply the plaster or lime paint. Wet or dry sand are to make sure its flush with adjacent area,
As always, use your best judgment and test small areas first.
Natural sealers, such as Vasari Mineral Sealer, is most commonly used in general areas. It can take dirt, wine spills and oil spills. It’s easy to apply, odorless, it breaths, is easy to fix or re-apply.
Vasari Wax is a great and the traditional way to finish plaster. It will give it protection as well as a beautiful luster.
Synthetic Sealers can be used on all of our products. Acrylics, epoxys and siloxanes / silanes all work on our materials. Different sealers might work better in different areas depending on project requirements, such as sheen, durability, impact resistance and waterproofing.
Shower plaster / TADALEKT maintenance
All Vasari products can be cleaned using water in most instances. Solvents such as lacquer thinner, soap and water or mild detergents can be used to remove stains. Do not use acidic cleaners or bleach. Salts and chlorine can damage plaster if not sealed or protected. Persistent water streaks can naturally weather plastering and leave a patina or water staining over time. Repeated water misting of plaster when first applied (before sealers) will reduce potential discoloration from weathering in the future. We always recommend Vasari Wax as the final coat in wet areas. This makes the plaster highly water resistant and easy to maintain.
Vasari expressly warranties Mineral Primer to be fit for the ordinary purpose for which they are intended for a period of 10 years for non-wet interiors installations, and 5 years for exteriors from date of installation when applied and used in accordance with manufacturer’s instructions within six months of purchase.
WARNING! If you scrape, sand, or remove old paint, you may release lead dust. LEAD IS TOXIC. EXPOSURE TO LEAD DUST CAN CAUSE SERIOUS ILLNESS, SUCH AS BRAIN DAMAGE, ESPECIALLY IN CHILDREN. PREGNANT WOMEN SHOULD ALSO AVOID EXPOSURE. Wear a NIOSH approved respirator to control lead exposure. Clean up carefully with a HEPA vacuum and a wet mop.
