As with any job like this we would always suggest that you practice and hone your skills first so in this DIY guide we run through the process of how to skim plaster a wall or ceiling. What is Skim Plastering? This is essentially how long you’ve got to work with it and get it on the wall before it’s gone too hard and it’s too late. Once skim is hard the only way of smoothing it is by sanding. If you're not confident with plastering large areas, plasterboard will achieve a flat surface with which to skim over. Wash everything in clean, fresh water removing and residual plaster mix. Once cleaned, place your tools out to dry.

So I'm guessing it's loose, echos slightly when you tap it, with a little bit of movement. Then, when you remove the wall paper you see something like this: As well as using plasterboard to fill a small hole to the corner of my window (as seen in the above picture), I also used plasterboard to one side of a window opening, like so: In accordance to the preparation list detailed above, prepare the wall or walls that you are going to plaster carefully and correctly. Wait for the bonding coat to set overnight. When you return the next day, use the wide scraper to gently chip off any protruding bits that'll get in the way when skimming.In terms of what face you should plaster over, it is generally regarded that you should plaster over the grey or coloured side as this should be the side that faces into the room. With plasterboard that has tapered edges, these should also be on the grey or coloured side as they also need to face into the room when the plasterboard is just being decorated and not skimmed as they can be filled to produce a seamless joint. If there have been drywall repairs or ceiling repairs, a skim coat will give a nice consistent surface to retexture or for priming and painting. Old Surfaces

This will dampen it slightly which is just enough to soften it and allow you to trowel it out and move it to a lower depression.If possible the mixing and movement should continue while the powder is being added as this will help prevent any lumps forming, as in the image above. Using plasterboard to fill a hole between plaster can be advantageous to using a base plaster/render (the stuff beneath the thin layer of finishing skim coats), for a number of reasons: Q4 finishing meets the highest visual surface requirements. It allows decoration with glossy wallpapers, paints, or varnish coats, as well as stucco marble and similar finishes. Sweep and remove dust: Once scraped over, use a stiff bristled brush to brush the entire surface over and remove any remaining dust or debris With Bonding Coat, it contains really large particles. It's no good for a finishing skim, it's just too rough. It does however provide a really good key for a finishing skim coat. Therefore, don't worry too much about getting it smooth, just concentrate on getting the levels right i.e. it shouldn't poke out too far and there shouldn't be a dip.

If you get it right, doing your own skim plastering can save you a lot of money. If you get it wrong it can cost you a fortune putting it right, so if you’ve never done any skim plastering, before doing it for real on a given wall in your home, practice first to perfect your skills. For both options, once the bonding coat has dried it's time to apply the finishing skim. This can be applied over the bonding coat, the existing plaster and the plasterboard. You may be doing the same, or you may just be skimming over little bits, leaving most of your existing plaster exposed. Either way, I have covered how to skim coat in another post. Here's a link to it which will open in a new tab for you. Roller - including the handle, obviously! Like the brush, we're using it to apply a PVA/water solution, so we're going for coverage, not quality, so just get a cheap one for this. Although, a short pile would avoid a lot of mess.

What types of plaster do we have available at Selco? Multi Finish Plaster Q3 prepares drywall surfaces for fine structured wall coverings and paint coatings, as well as top coats with a particle size below 1 mm. Holding your trowel at around 20°, run over the surface taking off the trowel marks and hard edges. When trowelling down, the idea is to take the high spots off and move them into any low spots so as you trowel off the high trowel marks, try to push them into any depressions. Again this takes a bit of time and practice to master. For me, when I was sorting out both bedrooms, I skim the lot, over the old plaster too. This is because I wanted to make sure I had a flat surface throughout and I'd already had a bit of practice at skim coating.

Very briefly, whilst I'm on the subject, there is one thing I really want to point out - as per the instructions of the Plasterboard adhesive, there is no need to PVA the masonry before you attach plasterboard, just clean down the masonry. You really do need to make sure it's cleaned down well, otherwise the adhesive will be attaching itself to dust and may separate from the wall in time. Once you are confident that the entire surface is smooth, take a spirit level place it across several areas of the wall. If the surface truly is flat, every part of that level will touch the wall and if it doesn’t there will either be a high spot or depression.Skim coating is a great way to make ugly walls and ceilings new again! A skim coat, also known as a level-five drywall finish, is a thin coat of diluted joint compound that can be applied by hand, paint roller or spray rig. Then it’s smoothed out by using a drywall knife or trowel. It’s an easy way to create flat and uniform surfaces on walls and ceilings so they can be painted or re-textured. As a rule of thumb, you should apply at least two skim coats to achieve a smooth and consistent surface. Below, you will find the top five reasons to apply a skim coat to your walls or ceiling.
