Plastering in Wallingford

Can You Plaster Over Artex?

The short and simple answer to this question is yes, you can plaster over Artex. However, you must also note that plastering over Artex may not be the best choice as Artex is porous and as such, you’d have to detach the stripping so as to get a smooth and even coating. In the event whereby your ceilings or walls have Artex on them, you’ll have to smooth the Artex in order to obtain a plaster of solid coat.

✓ Preparing Artex for plastering. First and foremost, you’ll have to detach any bumps before you can plaster over the Artex. Do note that you don’t have to completely remove the Artex, all that’s needed is just enough to get a coat of plaster. Make use of a scraper to get rid of the bumps on various Artex designs like swirl and bark. Once you’re through getting rid of as much bumps as possible, there’s the need to seal the Artex due to the fact that it can absorb the moisture out of the plaster which will cut the time to get a good finish to little or nothing. You can use a PVA and water mix to do the job!

✓ The PVA mix. This is done to seal off the porous Artex in order to stop it from absorbing moisture from your plaster which can make it start to crack and crumble. To do this, simply mix half PVA and half water, then use a brush to paint the mixture over the plastering area. Once done, you can give the plastering surface about two to three coats and wait for the solution to dry off within a hour or two.

Plastering over Artex is not as hard as it seems, but if you lack the confidence to complete the task, simply contact a professional for help.

Can You Plaster Over Tiles?

Yes, it’s absolutely possible to plaster over tiles but just because is possible doesn’t mean you should. Plastering over tiles is an option but it’s not recommended by experts due to several reasons. A good example is the fact that a tiled environment is in no way a suitable environment that can serve as a good bonding surface for a plaster. For the success of a plastering project, there’s the need for the surface to be able to bond to the PVA base coat. Due to fact that most tiles are slippery in nature and also lack of the ability to be able to absorb moisture, the PVA base coat layer will not be able to bond to the tiled surface, which will ultimately make for a weak surface upon the application of the plaster. Consequently, the plaster will easily flake and fall from the wall.

The inability to drill into the tiled wall surface after plastering is one of the major disadvantages that also arises when you decide to plaster over tiled surfaces. Most tiled surfaces are found in kitchens and bathrooms which are going to need appliances such as sinks, lavatories, kitchen counters and lots more. These appliances are designed to be installed on solid surfaces which would not be an easy task to carry out on tiles knowing there would definitely be great cracks or damages.

The best tip you’ll get if you’re considering to plaster on a tiled surface, is that detaching tiles from a surface can easily be done with a hammer and chisel, and that would save you a host of problems later in the future. However, if you still wish to plaster on your tiled walls, then you best bet would be to get a Blue Grit bonding agent. It works better than PVA and only needs one coat.

There are several different kinds of plastering. ‘Dot and dab’ refers to a base layer of plasterboard which is attached to a wall using ‘dabs’ of adhesive. ‘Floating’ is a technique where a backing or undercoat plaster is applied to walls. ‘Skimming’ or ‘reskimming’ refers to the very thin final decorative layer of plaster.

Plastering will fix small cracks in walls. Very small cracks may be fixed by simply reskimming plaster. More serious cracks will usually mean that you need to use new plasterboard or backing plaster. Larger jobs or deep cracks may need an experienced plasterer to come in.
