HRG - Heat Resistant Grout

VITCAS Heat Resistant Tile Grout 1000°C – Fireplace & Stove Tile Grout

Vitcas® HRG Heat Resistant Tile Grout is a specialist high-temperature grout designed for filling joints between tiles exposed to temperatures up to 1000°C / 1830°F. Available in grey and white, it is suitable for tiling applications around fireplaces, stoves, range cookers, boilers and other heat-exposed installations where conventional tile grouts may not provide adequate temperature resistance.

For a complete heat-resistant tiling solution, use Vitcas HRG Heat Resistant Tile Grout in conjunction with Vitcas HRTA Heat Resistant Tile Adhesive. This combination provides a compatible fixing and grouting system for suitable high-temperature applications, helping to maintain durable joints through normal heating and cooling cycles.

Applications

Vitcas HRG Heat Resistant Tile Grout is suitable for grouting compatible tiles in high-temperature environments, including:

• Fireplace surrounds and tiled fireplace openings.
• Stove surrounds and suitable tiled areas around wood-burning stoves.
• Range cookers and heat-exposed kitchen installations.
• Back boiler installations and suitable boiler surrounds.
• Other domestic and commercial applications requiring high-temperature tile grout.

Instructions for Use

1. Allow the Tile Adhesive to Set: Before grouting, ensure that tiles fixed with Vitcas HRTA Heat Resistant Tile Adhesive have fully set. Allow approximately 72 hours at 20°C, or longer where required by the installation conditions.
2. Prepare the Joints: Ensure that the tile joints are clean and free from dust, loose material and any excess adhesive.
3. Mix the Grout: Add clean water to the grout and mix thoroughly until a smooth, workable consistency suitable for application is achieved. Follow the current product instructions for mixing and application.
4. Apply the Grout: Using a suitable grout float, work the material evenly into the joints, ensuring they are properly filled.
5. Remove Excess Material: After approximately 30 minutes, carefully wipe away excess grout from the tile surfaces using a damp cloth or sponge, taking care not to disturb the filled joints.
6. Allow to Cure: Let the grout set and dry in accordance with the product instructions before exposing the installation to high temperatures.

Application Advice

For best results, allow Vitcas HRTA Heat Resistant Tile Adhesive to set fully before grouting. Under typical conditions, this requires approximately 72 hours at 20°C. Lower temperatures, higher humidity or site conditions may extend the setting time.

Always follow the current product instructions and ensure that the complete tiled installation is suitable for its intended operating temperatures.

Please note: Slight colour and shade variations may occur in both HRG Grey and HRG White due to natural differences between manufacturing batches, mixing and drying conditions. The final appearance may also differ slightly from product images.
