How to Apply Snowcem Exterior Masonry Paint

Snocem exterior masonry paint


  1. Ensure the surface is free of all weak and loose material such as dust, dirt, moss or contamination such as lichen, grease, oil, sealer, salts or efflorescence and anything that could affect the coating application. If necessary call us for advice on surface preparation and information on any special cleaning products you might need
  2. If necessary repair the surface using compatible materials.


  1. Where it is not possible to remove all of the existing paint and coatings, or the surface generally lacks absorbency. Then you can prime the surface with Cemprover primer and interbonder prior to the application of the paint. 
  2. Cemprover can be used neat for binding up loose and crumbly surfaces or it can be diluted with an equal volume of clean water when used as a primer over an existing coating.
  3. Cemprover can be applied either with a brush, roller or  spray gun if you need to cover a large area. 
  4. Apply 1 coat of Cemprover mixed 1:1 with water. Make sure the surface has been completely covered with the primer and allow to dry.
  5. Where the surface is very powdery or low strength such as distemper or lime-wash, again you can treat the surface with Cemprover prior to the application of Snowcem paint. Please follow the Cemprover TDS Instructions for:
    (i) bricks with sulphates,
    (ii) old cement paint surfaces and
    (iii) distemper and lime-wash surfaces.
  6. If in you are in any doubt or have any concerns regarding the preparation and suitability of Snowcem paint for your surfaces then please contact us either by phone on 01665 494034 or email. We will be only too happy to advise.


  1. Using your container measure out equal volumes of water and the Snowcem paint powder.
  2. To prepare the paint add the water to your mixing bucket and then add the snowcem paint powder. The general rule is 1 part powder to 1 part water by volume. This can be adjusted depending on the surface application. See the Snowcem TDS for more information. You can download the Snowcem TDS here.
  3. Using a paddle mixer or drill attachement. Start by mixing slowly as this will minimise any dust.
  4. Mix thoroughly until all the powder has been absorbed with the water taking care to include any powder from the bottom and side of the bucket.
  5. As you are working it may be necessary to give the paint a quick mix. it is not advised that you attempt to thin the paint further by adding more water.
  6. As Snowcem Masonry paint contains some cement you should only mix enough of the paint that you will use in around an hour.
    The amount you mix will depend on the application method you choose to use.


  1. Snowcem paint is best applied using either a large masonry brush or micro fibre paint pad,  
  2. Apply the Snowcem paint in two coats, allowing the first to set dry, allowing no more than 18 hours interval between coats.
  3. In warm weather, when surface evaporation is likely to be significant, assist curing of Snowcem paint by apply a mist spray of clean water.
  4. Allow the paint to fully harden before touching the surface.
  5. Clean tools and equipment with clean water prior to the Snowcem paint hardening on them.


For spray application care should be taken to choose equipment that is appropriate for cement based coatings, we recommend an HVLP spray system. For more information on spray application of the paint then please get in contact.

Before you start painting use our equipment check list above to get all the the tools you might need together. Wearing a paper dust mask while adding the snowcem paint powder to water is a sensible precaution as this can be a bit dusty but it’s not needed while actually painting. Wear old clothes if you don’t have any of the paper overalls. A plastic ground sheet can be useful while mixing the paint and will also protect surfaces during painting. We suggest you wear gloves at least while mixing the paint.
