How to paint with limewash
Purity Paint Application Methods and Tips
Purity Limewash Paints can be used for a variety of decorative finishes. Our standard application is the most common and provides a nearly opaque finish with subtle variation and texture. Our application methods and tips on this page aims to provide a straightforward introduction guide to the installation of our limewash paint products.
With lime mineral paint, always paint on an absorbent surface such as exposed masonry, or apply Purity Lime-Prep Primer to create a micro absorbent surface before applying lime paint. This step will allow your paint to "stick" and develop it's proper color.
Purity Limewash Paints are best applied with a block style brush that can hold a good quantity of material. The Purity Limewash Brush is a blend of bristle types which provides ideal workability and results in most circumstances. For most wall painting projects, a large 4" or larger block-style brush works best.
There are multiple ways to finish limewash for specific distinctive lime paint looks.
Standard and Opaque Finishes
Standard application method is to apply two coats of lime paint as it comes in the can. This will create a mottled, nearly opaque finish (or minimal show-through of brick or stone if painting over masonry - more on transparent washes below).
Several, layered applications will create a saturated opaque finish. This is usually accomplished with two to four thin coats of lime paint. Lime paint is thinner than latex paint and coats will typically apply faster and spread further. It is important to spread the paint as far as it will naturally go and not attempt to apply in a thick coating.
Standard wall application:
- For the first coat, apply at full strength and spread each amount applied as far as it will go. It should not be perfect and you should try not to over-brush. Apply in a crosshatch pattern or (vertical pattern if desired for the vertical brush finish). Pro tip: if your lime paint isn't spreading as far as you'd like, lightly mist the surface with a spray bottle right before applying paint.
- For best results, the second coat will require that the surface that you are painting is damp misted with a mister-sprayer or a spray bottle set to mist. Make sure the surface is lightly damp but not soaked and apply the second coat using the same brush method as the first coat.
Translucent Limewash Finishes
One or two applications of various dilution ratios will create a translucent finish. Purity Limewash Paint can be diluted with water up to 300 percent of volume to create a nearly transparent wash effect. This is a standard dilution ratio for wood-wash finishes.
Distressed Limewash Finishes
Applications of lime paint that are sprayed with water and/or wiped off with a cloth or scrubbing pad, or plastic bristle brush as the material is drying/setting will create a distressed or aged finish.
Applications of slightly differently tinted lime paints using various layering techniques can create mottled and unique finishes. We find the best results usually start with a darker shade and overlay with a lighter shade. Similar colors often work well together and contrasting colors can create a high-contrast effect.
Creating Custom Colors
While we do not offer custom color matching, mixing two or more colors can create a custom blend and all Purity Limewash colors are all compatible for blending to create custom colors.
Tips and Application Essentials
There are some specific methods that we find essential to produce the best results. For those of you who are familiar with staining wood, many of the same principals apply
1. Make sure that if your surface to paint isn't naturally absorbent (unfinished masonry or wood), that you do apply Lime-Prep Primer before painting with Purity Lime Paint. Please note that some bare wood surfaces can be damaged by direct application of lime paint without first applying a sealer to the wood. Contact customer support if you have questions about proper prep or apply to a test area to determine suitability.
2. Purity Lime Paint, primers, and sealers must be brushed for best results. Lime paint will apply faster with a brush than other paint, as it is a thin material compared to acrylic paints.
3. Apply in very thin layers (usually 2-3) with a block style brush and review as you go to make sure to clean up any "drips/runs" as you go on the wall surface. Only after it dries will you be able to see the build and color (it will appear much darker and more transparent when wet).
4. Maintain a "wet edge" and paint from one side of the surface to the other. Another method is the cloud technique and involves painting random "clouds" of lime paint and then blending the clouds into each other. Maintaining a wet edge is still required with the cloud method. The entire wall must be painted once started or there will be a darker layering appearance at the stopping/starting point. The wall can be lightly misted with water at your edge to preserve the wet edge for longer working times.
5. Do not "cut-in" lime paint like a traditional paint as this will create undesirable layering effect. In other words, don't paint lines around the edges of the wall or around windows - and then paint in the main body of the wall at a later time.
6. Wait 24 hours between applications for most consistent results. If you want to coat with another layer sooner, you can do this once dry but it may lift some of the previous coat into your current application (reducing the thickness of the coating). We recommend lightly misting/spraying the surface immediately before applying the second coat and subsequent coats. This will allow the lime paint to spread properly over the prior coat. You can lightly mist the wall to dampen it after applying the second or final coat. This can help the curing of the material and may also increase color variation in the wall if that is a desired effect. Do not wet wall to the point where water can run down the surface as this will cause water streaking.
7. If you decide to seal to create a wipeable surface, wait at least 48 hours after final application to apply Purity Sealer. For best results wait to seal until after 1 week of curing. Always apply Purity Limewash Sealers with a brush.
8. Make sure to use interior Purity Sealer for interior applications only.
Closing advise on preparation for your project
We recommend practicing different methods on sample boards to create a look that is suitable for the desired outcome. often, a 2'x2' plywood or drywall board is readily available at local building and home improvement stores. These sample boards allow you to try different techniques and fine tune your application methods before starting the project! It's nice to feel more comfortable with your application approach and finish expectations before starting on the wall. Always wear protective gloves, clothing, and eye protection. And don't forget to have fun creating your beautiful lime paint finish!
