Mineral Coatings for Masonry

Cathedral Stone Products Inc. has developed MasonRE® Mineral Coating, a potassium silicate mineral coating, for use on all masonry (mineral surfaces), and over latex and acrylic coatings. Similar coatings have been in use in Europe for over 160 years and are now produced for the first time in North America. MASONRE® Mineral Coating combines the advantages of silicate/mineral and silicone coatings. Unlike latex and acrylic coatings, they form a molecular bond with the masonry substrate. The coatings are 92% vapor permeable. Please note, MasonRE Mineral Coating is a natural product. A mock up panel should be applied prior to full application to determine if the product is suitable for application. A pull test can be done, if specified, to determine if the coating has propery bonded with the substrate.

  • Fire Retardant.

  • Withstands Extreme Climate Conditions.

  • Water Repellent.

Application Procedures

Surface Preparation
MASONRE® Mineral Coating should only be used by experienced users. MASONRE® Mineral Coating can be applied to any sound masonry or plaster surface. (Do not use on wood, plastic, or apply over oil or gloss coating.) The surface must be clean, solid, dry and free from efflorescence. The surface must be completely dry at the time of application. MASONRE® Mineral Coating is designed for vertical surfaces only. Horizontal surfaces that receive foot traffic, or where water can pool, are not suitable for application. Cracks and spalls must be repaired and cured before coating. Cracks can be filled with Jahn M30 or M40 mortars. To ensure even penetration of the coating, make sure repairs have been made with repair materials that are compatible to the substrate. Temperature (ambient and substrate) must be at least 45° F (8° C) and below 90° F (32° C). Do not apply the MASONRE® Mineral Coating when precipitation is expected within 48 hours of application. Do not apply MASONRE® Mineral Coating when the temperature is expected to reach the dew point within 24 hours. The coating needs adequate time to bond to the substrate and moisture disrupts this curing process. Protect adjoining surfaces from splashes. MASONRE® Mineral Coating can only be removed while wet. Once MASONRE® Mineral Coating dry they CANNOT be removed.

Mixing
Do not mix MASONRE® Mineral Coating with water. If MASONRE® Coating needs to be thinned out add Cathedral Stone Fixative until the desired consistency is reached. Mix MASONRE® Mineral Coating with a 3000 rpm drill prior to use. When installing multiple units of coating, be sure to box-mix (Box-mixing is the blending of coating by pouring alternately between two containers.) This will help alleviate minor color inconsistencies between batches.

Substrate absorption definition: The absorption must not be too high or too low for the coating to be applied correctly. Absorption can be tested by applying small amounts of water (drops) on the vertical surface to be coated. Normal absorption can be defined as the water absorbing into the substrate without beading on the surface. High absorption can be defined as water being absorbed so quickly that all traces of water seem to disappear rapidly. Low absorption can be defined as water laying or beading on the surface of the substrate (masonry must be etched in cases of low absorption).

Application
Protect all areas not to be coated prior to application. Substrate must be completely dry before coating. Do not work when precipitation is expected within 48 hours of installation. The coating needs adequate time to bond to the substrate and moisture disrupts this curing process. Apply liberally and spread well, filling all pores and cracks. Work wet into wet, and from corner to corner, or until an architectural break. MASONRE® potassium silicate mineral coating should be applied with a short bristle brush. Brushing increases the absorption of the coating into the masonry, resulting in a longer lasting, more durable coating. Spraying and rolling the coating is possible. Allow the first coat of MASONRE® Mineral Coating to dry of at least 12 hours. Apply a second coat of MASONRE® potassium silicate mineral coating in the same fashion; work wet into wet.

Important Points

  • Make sure the substrate is completely dry and there is no expected dew.

  • Protect coatings from all forms of moisture: rain, dew, snow, etc. for 48 hours.

  • Temperature must be at least 45°F (8°C).

  • Protect any surfaces not to be coated.

  • Do not add water to MASONRE® Mineral Coating.

  • Always box mix when installing multiple units of coating.

  • Always work wet into wet, corner to corner, or until an architectural break.

  • Areas applied on different days can dry a slightly different color depending on ambient conditions.

Clean Up
Place tools immediately in clean water when pausing work (15-30 minutes or more). Clean tools with clean water immediately after finishing work. Dried MASONRE® Mineral Coating is insoluble in water. MASONRE® Mineral Coating can be removed from non-porous surfaces with clean water while still wet.

Packaging
Consists of 25 kg of MASONRE® Mineral Coating in a 6-gallon plastic pail.

Coverage
Coverage depends on the absorption and structure of the substrate. Determine coverage with a trial application.

Normally absorptive, smooth surfaces with two coats:
One unit of MASONRE® Mineral Coating (approx. 5.0 gallons) will cover approx. 1200 square feet for a single coat and approx.750 square feet when two coats are applied. Coverage rates will generally be higher with darker color coatings.

Safety Information
Eye protection should be worn during mixing to protect eyes from splashing. Avoid contact with skin and mucous membranes. Work in well ventilated areas.

Storage and Shelf Life
Store in a dry area, away from direct sunlight. Storage conditions should be in the range of 40° - 80° F with low to average humidity. Average shelf life is six months in original, unopened packaging.
