Each Limestrong mineral finish has a unique aesthetic with characteristics best achieved by an experienced artisan with knowledge, skill, and ability with our line of plasters. While plaster professionals have the optimal skill set to achieve a desired finish, those with stucco application and drywall finishing experience can quickly learn the techniques to successfully apply lime plaster. Artistic and intrepid DIYers have also had great success using Limestrong.


Can Anyone Apply Limestrong ?

Yes, we have engineered Limestrong for the beginner and professional alike with easy to use formulas and streamlined process. Many DIY customers have great success and are very pleased with the outcome.

Can I Do Tadelakt Myself ?

Yes, but with a BIG caveat. Successful tadelakt relies on an understanding of timing and decision making that comes through experience. That said, we encourage all seasoned plasterers to practice the steps and process of our tadelakt system before attempting a real project. If you aren’t a seasoned plasterer, we also encourage you to consult with an experienced tadelaket professional.

What Substrates Can I Apply Limestrong To ?

Marble, Stone, and Sand: primed or previously painted drywall.

Sand and Base: non-drywall substrates like brick, stucco, cinder block.

Tadelakt for wet areas:  fully waterproof substrate system.

Tadelakt for dry areas: drywall

Limestrong Limewash: plaster

Please see our PDF GUIDES for detailed information.

Do I Need To Use a Primer ?

Yes, if the drywall hasn’t been primed. No, if the drywall has already been primed or painted.  Limestrong primer grit is recommended to add to primer for surface texture.  Durable and absorbent surfaces with light texture like plaster, stucco, adobe, brick, and cinder block do not need to be primed.

Can Limestrong Plasters be Repaired ?

Yes, small nicks, dings, and scratches are relatively easy to repair with lime plaster.  Large drywall repairs requiring a patch will need the wall to be re-plastered. A new coat of Limestrong can be applied over previous ones. For stains, Limestrong soap sealer helps prevent absorption and makes plastered surfaces more cleanable.

How Do I Choose a Color ?

We have created several tools to help our customers choose color:

  1. Our color swatches are a digital representation of our 98 standard colors.
  2. For each Limestrong color, the user can color match to colors of standard paint brands. This allows user to get a color chip from their local paint store and see a close color match.
  3. Using our sample calculator, users can calculate the small amount of pigment needed to make a small sample board to visualize your color and finish
  4. We can make a custom color sample board of any of our finishes in any color and mail it to you.

How Do I Make a Sample ?

The sample calculator on our website will calculate the weight of pigment needed based on the quantity of plaster you need: a pint, quart, or gallon. For two coats on a 2 foot  square sample board, we recommend 1 quatr of mixed plaster. Once your sample pigment and plaster arrive, to  make a sample size batch, use a basic digital scale to weigh out the exact amount of water + pigment + plaster and mix. Instructions are included in the sample.

Do I Need To Use the Soap Sealer ?

Limestrong Soap Sealer is an optional step in the Limestrong system. Adding a coat of Soap is a simple and cost effective way to naturally seal your finish. The Soap reacts with the lime in the plaster to create a seal that repels dirt and moisture and adds a silky feel to the plaster finish. As long as the Soap is properly diluted, the appearance of the plaster does not change .

Do I Need to Use Primer Grit ?

Primer Grit is an optional component in the Limestrong system. Limestrong plasters will adhere to primed surfaces without primer grit, however adding primer grit provides newly primed surfaces with a toothy texture that makes applying the first coat of plaster especially easy.

Can You Refer Me to an Artisan in my Area?

Please see ‘Find a Pro’ on our website for plaster professionals in the US and Canada.

Where Can I Buy Limestrong ?

LUNGS, SKIN, + EYES: Limestrong is made of hydrated lime which has a high pH (caustic). As such, direct exposure to lime powder dust and mixed plaster can cause irritation and alkaline burns. Breathing lime powder dust can cause respiratory irritation, touching dry and mixed plaster can cause skin dehydration and irritation, and lime powder dust can cause eye irritation and damage. If irritation develops, seek medical attention.

LUNG PRECAUTIONS: When mixing plasters, wearing a particle mask or respirator that covers the nose and mouth is recommended. TREATMENT: If lime powder dust is inhaled, move immediately to fresh air.

SKIN PRECAUTIONS: Protective clothing like long-sleeved shirts, coveralls, and gloves are recommended. A lanolin-based barrier cream can provide additional protection for the face, neck, hands, and forearms. If cuts, scrapes, or scratches are present, it’s recommended to take extra effort to protect vulnerable skin. TREATMENT: Wash exposed skin thoroughly after handling lime plaster with white vinegar and/or cold water. Vinegar will neutralize the alkalinity of lime plaster on skin. Washing with hot water will exacerbate lime irritation.

EYE PRECAUTIONS: To prevent contact of airborne lime powder with eyes while mixing and applying lime plaster, wear protective glasses. Avoid rubbing the eyes with unwashed hands that have been in contact with wet or dry lime plaster. TREATMENT: Immediately flush eyes liberally with cold water for several minutes. Hot water will exacerbate lime irritation.
