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.

Artexing a ceiling can be a tricky job, but whether you’re considering hiring a professional or DIY, it’s helpful to know how it’s done.

Artex is available either in a paste or powder form. The paste is ideal if you’re making small repairs or additions to an existing ceiling. But, if you have a whole ceiling to cover, the powder is more cost effective. When you’re ready to get started, you’ll need to mix the powder up with cold water according to the instructions.

It’s possible to artex over plaster, plasterboard or paint. If you have a plasterboard surface, you should tape and fill any joints or cracks before you begin. Plaster and plasterboard both require a coat of sealant or primer first. You can usually artex straight over paint, but any gloss paint should be sanded down, and any dark paints covered with a layer of white.

Artexing can get quite messy, so make sure you empty the room you’re working in as much as possible, lay down sheets and wear protective clothing and glasses. You might want to practice on a piece of board before you start on the ceiling.

Start by using a brush or roller to cover a 500 square cm area with a generous layer of artex. Then use a brush, comb or roller to create your chosen texture. Every time you do a new section of ceiling, try to blend it with the other sections you’ve done. Don’t be tempted to cover the whole ceiling before you start adding texture – the artex will dry too quickly for you to do it all in time.

Artex usually needs 12-24 hours in a well-ventilated space to dry completely.

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.

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.

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.

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.
