GREY PLASTER FIREPLACE HOW TO
GREY PLASTER FIREPLACE PATCH

The plaster should be first applied so that the surface is flat but not necessarily smooth. It is important that the plaster is applied evenly i.e. A thickness of approx 3-6mm should be applied. As a guide the amount of water required is approximately 200 ml per kilo of plaster. Take care not to mix the material too wet. It is best to mix the plaster in the bucket in which it is supplied. There should be no traces of ordinary Portland cement or gypsum plaster on the tools or in the mixing buckets. The material should be mixed with cold tap water to a useable consistency with a plaster mixer / drill attachment. Plastering should commence when this PVA becomes tacky. In both cases the area to be covered should be prepared by coating with undiluted Vitcas®PVA Adhesive Sealer. If applying onto VITCAS®HIGH TEMPERATURE PLASTERBOARD then the boards should be fixed with the rough reverse face exposed for plastering. If possible apply heat after day one ie light the fire or use another type of heater. The Vitcas®Fireplace Render should be left to dry for at least 3 days in temperatures above +20☌ and for longer if moisture is still present as apparent by the colour of the material. If applying onto VITCAS®FIREPLACE RENDER it is important to ensure that the Vitcas®Fireplace Render is fully dried prior to applying Vitcas®Heat Resistant Plaster. The maximum recommended thickness of the material is 6mm. *We recommend rendering and plastering the whole chimney breast with VITCAS® RENDER & PLASTER SYSTEM. The plaster can only be applied onto Vitcas Fireplace Render or onto Vitcas High Temperature Plasterboards. The plaster should be used in the areas subject to intense heat approx 3m2 (32 ft2) around the fire opening. The procedure for mixing and applying Heat Resistant Plaster is NOT the same as for ordinary 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. Protection up to 650☌ (1200☏) 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.

If you have any plaster issues not mentioned here, leave a comment below and I’ll try to answer as many as I can about how to resolve the issue.Heat Resistant Plaster is high temperature smooth finish render. It will start showing you leaks and settling before anything else, so look for the signs and fix the issues before they demand your attention in a more expensive way.

Remember, plaster is the canary in the coal mine and these are just some of the most common plaster problems. Use the steps in my post How To: Repair Plaster Walls to get things stabilized again. If you see bulges in your wall or ceiling and the plaster can be pushed back up against the wall, then it’s time to reattach that section of plaster. Just like delaminating cracks, bulging plaster looks exactly the same, except this time there aren’t cracks in the surface. I have seen a plaster wall come completely loose of the lath and bulge out about 4 inches from the wall without falling or even cracking! It’s not just cracks that mean plaster has come loose of its lath. Water and plaster are not a good combination, so find the source of the leak first and do everything you can to stop the water. If not repaired soon, the damage will just continue and you run the risk of developing mold in the affected area.

Use the steps in my post How To: Patch Plaster to repair the damaged sections. You may reach this stage without any noticeable water stains, but when this happens, a portion of the plaster will have to be removed and patched. Once the water damage becomes severe, then the plaster will begin bubbling and bulging.
