Terra Cotta Glaze (formerly MasonRE Terra Coat) is a non-yellowing, water-based, acrylic coating that highlights the natural color of masonry by providing a clear, semi-gloss sheen. The treatment does not alter the natural texture of the surface, nor significantly affect the vapor transmission qualities of the substrate. Terra Cotta Glaze provides a durable finish to terra cotta and masonry surfaces.

Use Jahn M100 or M125 to repair the clay body of terra cotta tiles where necessary. The repair mortar must cure for 14 – 28 days before the application of Terra Cotta Glaze . Apply Potassium Silicate Coating to the substrate and wait 24-48 hours before applying Terra Cotta Glaze . The surface must be clean, dry and free of oil, grease and other contaminants.
Mix well prior to application. Apply using airless paint spray equipment, brush or roller. When using an airless sprayer, use a 0.015 or 0.018 fan spray tip and reduce pressure to point of minimal misting or fogging to produce a wet application. Multiple applications may be necessary when applying to porous substrates or when a high gloss is desired; when this occurs, apply coats at right angles to each other with 4 to 6 hours between applications.
At 75° F (24 ° C): To touch 30 to 45 minutes. To handle: 2 to 3 hours. To recoat: 1 to 2 hours. Curing time varies with surface temperature, air movement, humidity and film thickness.
Clean equipment after use with mild detergent and water.
The ideal temperature conditions for applying Terra Cotta Glaze is between 60° – 90° F. If the ambient and substrate temperatures do not fall in this range, call a Cathedral Stone Technical Representative for special instruction.

Coverage will depend on substrate absorption. Coverage rates are approximate and a test application must be performed to determine the exact coverage rate to achieve desired performance characteristics and aesthetic appearance before beginning a job.
