Substrate Quality/Pre-Treatment:
Ensure all surfaces are clean and dry. For dusty surfaces, prime with a mixture of 4 parts water to 1 part PVA Bond and allow it to dry.
Application:
Apply using a cartridge gun. Cut the cartridge tip carefully to avoid damaging the thread, then attach the nozzle and cut it to the correct size. Follow the liner manufacturer’s instructions for application.
Limitations:
As liner and block types may vary, always check the compatibility of this product with the liner manufacturer’s system and follow their installation guidelines. Protect joints from rain until construction is complete. In accordance with current standards, all flues must be smoke tested after insulation and again once the appliance is fitted, in line with BS 5440 Part 1 or an equivalent standard by an approved installer, before being put into service. It is the user’s responsibility to ensure the product’s suitability by consulting with the flue liner manufacturer prior to installation.
