Think about the heat when you are plastering

The conditions are crucial to the quality of plastering. Ideally you want them to be perfect so it allows the plaster to dry uniformly. It will ensure a much better finish, reducing the risk of cracks and other problems. As some of the top plasterers in Sheffield, we have plenty of experience. We can advise clients on the best conditions for plastering and provide tips on what to do if they aren’t ideal.

The problem with heat

Plasterers SheffieldMost people would assume that it is better to work with plaster when it is warm. In some cases that would be correct, but when it is excessively hot it can lead to major issues. It could completely ruin the finish.

The main problem with heat is it speeds up the surface drying time. It can happen because the substrate is too warm, because the air is evaporating the water faster, or a combination of the two. What this does is cause unnatural shrinkage. The end result can be cracks.

Another issue is the heat can reduce the set time with plaster. What it means is the timeframe for getting it on the surfaces is smaller than it normally would be. It can lead to problems, especially if plasterers rush to get it on. Even worse, it can cause cold joints. These are areas where the plaster does not bond properly, potentially leading to a number of different flaws like de-bonding.

Finally, the plaster may have an uneven colour. This can happen because of variations in the moisture content. In many cases that won’t be an issue as you will be painting or hanging wallpaper. However, if it is decorative plaster, you want it to be uniform.

What to do?

As long serving plasterers in Sheffield, we know plenty of skills, tips, and tricks to get the best results. There are a number of things you can do if it is excessively hot.

A great idea is to pre-soak the substrate. It can offer a massive benefit, reducing the temperature of the surface to ensure it won’t pull as much water from the plaster. It can help to ensure a more even drying time.

Another thing you can do is start earlier. You want to avoid mixing and applying plaster when it is warmest. An early start means it can be cooler and give you more time.

It can also be helpful to try to reduce the temperature of the plaster mix itself. An easy way to do this is to use colder water. It will take longer for a cooler mix to warm up and start drying.

There are also several things you can add to the plaster to help deal with the heat. For example, you could go with a slow setting cement. Or you could try a set retardant or water reducer. In some cases adding more water to the mix can be sufficient.

Ideally what you need to do is think about the air temperature and humidity level. You can then decide exactly what plaster mix to use and when to start working.
