Artex is a popular ceiling finish, whereby the surface is textured using a material similar to plaster. It is a trademark of Artex Ltd, a UK-based firm. Widely used in the UK in the 1970s, its popularity has waned in recent decades due to the fact that it is difficult to get a seamless finish during repairs. As a result, repairing damaged Artex can be a laborious task and one that needs to be done carefully.
Cover all floors and furniture with a dust sheet, then use the chisel and club hammer to knock away any damaged or crumbling Artex, and use a stiff brush to remove all dust and debris from the area. You will need to use a stepladder to access areas at height.
Fill the damaged area with putty, using your putty knife. Let it set and dry before carrying on.
Use fine grade sandpaper to give a smooth finish to the putty, and use a brush to apply a layer of sealant.
Mix the Artex with water until you have achieved a creamy consistency.
Brush a liberal amount of Artex onto the area that you have just applied sealant to.
Use your paintbrush to create the texture that matches the existing ceiling. If the ceiling has a stipple effect, simply use a stipple brush.
Let the Artex dry for 24 hours, and then paint in your chosen colour.
If you are repairing a large area, you may wish to cover the existing surface with plasterboard.
Always wear a dust mask, as older Artex surfaces may contain asbestos.
