For best results, make sure you apply it with firm pressure to get a high-quality and smooth finish. It can also serve as a good base if you want to add some decorative finishes. The setting time for the Multi-Finish Plaster is a speedy 90 minutes, which makes it a good choice for projects on a time limit. Multi-Finish Plaster is perfect when you have a variety of surfaces to cover, and it works best for low to medium suction backgrounds. You can also spray it on, which is a fasterwork but will require more dust sheets to protect other areas of the room. Before application, dampen the wall surface and apply to the wall by pressing the plaster on with high pressure to get the best result. Hardwall plaster is another type of undercoat plaster and one of the fastest drying plasters, and is mostly used on masonry surfaces like aircrete and medium density blocks, and bricks. The consistency of bonding plaster allows you to spread it smoothly and get a good finish. Simply dampen the wall’s surface before applying, and you’re all set to begin. Bonding plaster is ideal for walls and ceilings that have a smooth finish. Before you apply your top coat or ‘finish’ plaster to a wall, you might need to use a bonding plaster first to help the top coat of plaster stick to the wall effectively. This is an undercoat plaster also known as fixing plaster. As mentioned above, some plasters are more or less suitable for various wall types, so be sure your chosen plaster will be suitable for the area you’re plastering. You can purchase a range of plasters for different build situations and finishes. You’ll need to dampen the wall a little to improve adhesion of the plaster, but if you take the time to smooth the plaster over before it begins to dry, it should stick pretty well. These types of surface are the Goldilocks of plastering – just right. An example of a medium suction surface is normal household brickwork. Medium suction backgrounds are the middle-ground. Make sure to use a bonding agent so your plaster sticks (more about that later). Second is that a low suction wall needs to be prepared before applying the plaster. One is that the plaster will only dry by setting naturally, so you might have to wait to continue decorating. The benefit of plastering a low suction background is that you don’t have to worry about the plaster drying out too quickly while you’re applying it, but there are some drawbacks. Low suction backgrounds mean that the wall is only slightly porous - so it won’t take the moisture out of the plaster. To solve this issue, apply water to the wall prior to plastering until it runs down the wall – that means the wall has absorbed all the water it can won’t leach it out of the plaster. The benefit of applying plaster to a high suction wall is that it will stick very well, but it might dry out too fast or crack as it dries. High suction backgrounds mean that the wall is porous – as in it will quickly suck moisture from the plaster while you’re applying it. There are three types of wall, or ‘backgrounds’, in the plastering world - high suction, medium suction, and low suction backgrounds. Different plasters will work best on different walls, so before you buy your plaster, you’ll need to make sure it will stick to your wall. Face mask and goggles – to stop you breathing in plaster powder, and protect your eyes during the workīefore you get started, it’s important to figure out what kind of wall you're working with.Stepladder, platform, or stilts – to reach every piece of the wall and/or ceiling.Sandpaper – to smooth down any rough patches once the plaster is dry.Mixing stick and/or paddle – to mix the plaster to a good consistency.Hawk – for holding plaster during the job keeping it close at hand.Corner Trowel – for finishing off those corners easily.Plasterers Float – for smoothing over the plaster and making sure it is as flat as possible.Plasterer’s trowel – used for scooping and spreading plaster.Plaster – In the quality and quantity needed for the job.You don’t necessarily need all of these exact items – but you will need items that will do the same job: This is even more important during a plastering job, where plaster can dry out if left unattended. It’s always a good idea to be fully prepared for a DIY job so you don’t have to down tools and leave the job halfway through to stock up.
