Vitcas Heat Resistant Plaster Summary

Vitcas Heat Resistant Plaster

High temperature smooth finish render. Protection up to 650°C (1200°F) Vitcas® Heat Resistant Plaster is a replacement material for gypsum plaster where the temperatures are too high for gypsum plaster to stay on the wall.
Do not treat as Gypsum Plaster. For use around the opening of cassette fireplaces (sometimes called hole in the wall fires) and adjacent to wood burning stoves and range cookers where the area of the wall is subjected to intense heat.

Preparation
The plaster should be used in the areas subject to intense heat approx 3m (10 ft) around the fire opening. Maximum recommended thickness of the material is 5mm. Remove all traces of old render and plaster on the wall or part of wall to be treated. Re-render using VITCAS®FIREPLACE RENDER prior to applying Vitcas® Heat Resistant Plaster. It is important to ensure that the Vitcas®Fireplace Render is fully dried prior to applying Vitcas®Heat Resistant Plaster. The Vitcas®Fireplace Render should be left to dry for at least 3 days in temperatures above 18 degrees centigrade and for longer if moisture is still present as apparent by the colour of the material. If possible apply heat after day one ie light the fire or use another type of heater. Prepare the area by coating with undiluted Vitcas®PVA Adhesive Sealer.

VITCAS Heat Resistant Plaster & High Temperature Plasterboard
If you need to apply Heat Resistant Plaster onto a board then we ONLY recommend using VITCAS®HIGH TEMPERATURE PLASTERBOARD which is designed for this purpose.

For plastering the boards whith Vitcas Heat Resistant Plaster should be fixed with the rough reverse face and the board sealed with neat PVA before starting to plaster when the PVA becomes tacky.


Application
The material should be mixed with cold tap water to a useable consistency with a plaster mixer / drill attachment. There should be no traces of ordinary Portland cement or gypsum plaster on the tools or in the mixing buckets. It is best to mix the plaster in the bucket in which it is supplied.
Take care not to mix the material too wet.
As a guide the amount of water required is approximately 200 ml per kilo. A thickness of approx 3-6mm should be applied. It is important that the plaster is applied evenly i.e. no featheredges. The surface finish must be obtained during flotation with the trowel. The material cannot be sanded when dry. Due to the surface being dense and non-porous when dry it is not suitable for finish skimming. Any minor cracks can be repaired using VITCAS® HEAT RESISTANT FILLER. When dry the finished surface forms a very hard heat resistant surface that can be painted over as required. VITCAS® HEAT RESISTANT PLASTER must be allowed to air dry for at least 3 days before lighting fire.
Coverage: 20kg bucket will cover approximately 2m2 (20 ft2) at a thickness of 6mm (1/4”)

Storage
Keep any unused material dry and store in a cool dry place away from children and pets. Warning: Do not breathe the dust. In case of contact with skin and eyes rinse immediately with plenty of water and seek medical advice. After contact with skin, wash with water Wear suitable gloves and eye face protection. Keep out of reach of children.
