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.

Can You Plaster Over WallPaper?

If you have wallpaper installed on your wall surface and you’re considering plastering the wall, when you put into consideration the stress involved in removing a wallpaper you may want to consider plastering directly over the wallpaper. This is quite understandable as removing a wallpaper can be quite time consuming and tedious, but plastering directly over wallpaper is a mistake that should never be made. Plastering over wallpaper is in no way a viable option due to the fact that it can only turn out disastrous after a couple of weeks or even days in some cases as the plaster will crack and crumble. As a result, you’ll have to firstly scrape off the wallpaper in order to assist the plaster get to be firmly secured to the wall behind.

When you plaster over a wallpaper, this will make the wallpaper wet and it’ll absorb the moisture. And once the plaster does not have moisture, the only result is for it to crack and start to crumble. Hence, plaster and wallpaper is never a good combination.

Asides from cracking and crumbling, anther issue is that the wallpaper will bubble. You can actually key the wallpaper with the help of a knife and it might look secured for some time, however it’ll eventually crumble and you’d have to scrape off the plaster complete to start all over again. The wallpaper will bubble as the plaster can’t be keyed into a wallpaper and the wallpaper will only work as a barrier between the plaster and the wall.

Overall, plaster always needs to slowly dry off as well as a good and proper surface to grip to. No matter the amount of PVA mix you spread on the wallpaper, it will always remain a barrier. So you’d have to remove the wallpaper completely to get a great result.

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.

If your artex ceiling is looking tired or you just fancy a change, you can try plastering over your artex. You have two options when it comes to plastering over your artex: plasterboard or skimming.

Covering your ceiling with plasterboard is a good option if you suspect the artex may contain asbestos. If done carefully, it doesn’t involve disturbing the artex, reducing the risk of asbestos exposure.

You also have the option to skim over your ceiling. The first steps to this involve removing loose and flaking parts, cutting off stipples and sanding your ceiling down. So, if there’s a chance your artex ceiling may contain asbestos, this isn’t the right solution for you. However, if you’re sure there’s no asbestos in your ceiling, then sanding down and skimming over your ceiling can be a great way to create an attractive result.

It’s worth noting that both putting up plasterboard and skimming plaster can be difficult jobs. Although possible to DIY, you’re likely to get much better results if you hire a professional.

What Is Plaster Made Of?

Plaster is one of the most commonly used materials when it comes to building construction. It’s a crucial component that’s incorporated in coating walls, ceilings as well as partitions and it hardens on drying. Plastering is one of the most ancient building materials which has taken over mud to plaster reed or sapling huts so as to serve as a protection against the elements. Here, we’re going to take a look at the multiple compositions of plaster. These components are very important due to the fact that they form a protective coating on whatever they are used on. They work to protect surfaces such as ceiling and underlying walls from scratches or any form of damage.

Plaster comprises a few materials which includes gypsum, lime or cement and all operates in a similar way. Gypsum is made of calcium sulfate dihydrate and it’s the main component of main forms of plaster, sidewalk chalk, blackboard, drywall and more. Meanwhile, lime plaster is made up of sand, water and lime ( mostly non hydraulic hydrated lime). And lastly, cement which is a mix of suitable plaster, portland cement, sand as well as water.

The plaster is usually produced as a dry powder which is mixed thoroughly with water to create a stiff but also a paste that’s workable immediately before it’s applied to the wall or ceiling.

It’s quite easy to confuse a drywall with a plaster but there are some differences. Not only is plaster a much older style of wall construction than dry wall, but it’s also a lot more expensive than installing a drywall. Plaster walls are also able to provide you with a more durable finish when compared to a drywall and it makes for a better quality finish.

The fact is several buildings contain artex as well as other textured coating on walls and ceilings which are all likely to contain asbestos. However, artex itself is not the main threat here but the potentially deadly harmful fibres that’s contained in it. In this post, we’re going to look at whether or not artex truly contains the deadly abestos.

The short and simply answer to this question is yes, artex can definitely contain asbestos, however not all artex will contain asbestos. The main reason asbestos was a popular construction material is because it was not only cheap and strong but also because it was very durable and long lasting. It was used in numerous construction materials ( which includes artex ) before it was finally banned in the year 1999. unfortunately during the time when artex was very popular in the 60’s, 70’s as well as 80’s, asbestos was still very much in use during the period. And as a result, a lot of the artex incorporated during that period will contain the deadly asbestos fibres. However, this does not only apply to artex, but also other textured coatings containing asbestos were incorporated in construction until 1999 when asbestos was formerly banned in the UK. These asbestos containing materials are often used on walls as well as ceilings of residential properties.

Unfortunately, it’s not possible to know an asbestos containing artex just by looking at it. In order to determine whether or not an artex contains the deadly asbestos fibres, it’ll have to be sampled and tested in a laboratory. What’s more? While several artex contains asbestos, asbestos free artex was available from the 1970s. However, since it’s impossible to determine using the naked eye, all artex installed before the ban will be assumed to contain asbestos.

How To Plaster A Wall

In order to plaster your wall successfully, you’ll firstly need to get the appropriate tools and materials for the job in place. The tools you’ll need to have includes a trowel and bucket trowel, plasterer’s float, corner trowel, hawk board, two buckets, mixing stick or a paddle, adequate plaster, PVA , dust sheets, clean water, sandpaper, stilts or step ladder as well as a dust mask.

✓ Prepare the wall. You’d have to make sure that you lay down a dust sheet so as to protect your floor and also gather any possible spillage or debris of plaster, before you start working on the walls. Get rid of all the dirt, dust and debris as this is very important for the success of your project if you’re going to be plastering on a worn out and old wall. Also, cover the holes and cracks in the walls with a screen tape

✓ Apply PVA to the wall. This will help ensure the layer you’re using will not dry out at the same time.

✓ Mix the paster. Mix the plaster according to the instructions given in the manufacturer’s manual.

✓ Apply the plaster onto the wall. Upon cleaning of the walls and successful mixture of the plaster, the next step is to apply the mixture to the wall using the hawk board, trowels and a floating tool.

✓ Skim and smooth. After the the first coat has dried after waiting for about 30 minutes, the next step will be to wipe out the bumps and lumps using a trowel to smooth over the surface. Once this is done you can then scrape the wall with a devilling float.

✓ Apply the second coat of plaster

✓ Apply the finishing touches. This includes polishing your work by adding some water to the surface with a spray gun and using the trowel to further smoothen out the surface.

✓ Painting and wallpapering.

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.
