The trick to troubleshooting cracks, efflorescence and mould growth

You can experience a number of different issues with plaster, both inside and outside of a property. They can happen when it is new or may develop over time. For example, it could be flaking or not sticking well. Or you could have cracks, efflorescence or mould. Luckily, we can help, giving clients support from the best plasterers in Sheffield.

Many plastering issues come back to problems with preparation. It may have been the surface was not primed or cleaned correctly. Grease, dirt, and dust can undermine the plaster’s ability to stick. Moisture can also cause problems. Or the issue may be overworking the plaster or getting too much air in the mix.

What we want to look at today is three typical problems and how to troubleshoot them.


Plasterers SheffieldTackling cracks in plaster is vital for keeping the walls smooth. You also generally need to fix them ASAP to stop things from getting worse. Cracks happen for multiple reasons. Examples would be not applying the plaster correctly and shifts in the structure.

When you are fixing a crack, you have to determine what caused it first. If there is a larger concern with the building, you may have to reinforce the wall prior to re-plastering. When there is only a small crack though, you could fill it and smooth everything out to make it look good again. Talk to us if you need the foremost plasterers in Sheffield to examine and repair cracks.


Next we have a situation where a white powdery material appears on the walls. It is actually salt coming out of the plaster. This may not harm anything, but it doesn’t look nice. To dispose of it, you have to clean the wall very well. You then need to find out what is causing the moisture that’s making everything happen. Rectifying the underlying issue will aid you in keeping the efflorescence from returning.

Handling these complications comes down to taking action at the right time. You also need to make use of the right methods and materials. Using the correct fillers, sealants, and treatments for efflorescence can help considerably. Understanding how to mix and apply plaster properly can help you stop it from appearing. You also need to pay attention to the environment.


We will finish by discussing how you can prevent mould growth and moisture. Both can be issues, but plasterers in Sheffield can help. To keep these two away, you will need a solid moisture barrier. Decent ventilation is essential too. This is particularly true in places like kitchens and bathrooms. Here, humidity tends to be high.

Using anti-mould additives or paints on internal ceilings and walls is a good move. It helps to stop growth, keeping your house clean and healthy. Should you find any leaks, fix them immediately. It ensures you can halt the conditions that mould likes before it’s able to take hold.

Keep your attention on signs like damp patches and condensation. They could be telling you about a larger problem. Take early action to stop mould from making itself too comfortable. Finally, keep in mind that maintenance is crucial. Look for problems and clean everything up. Do so before they turn into a major problem for your plaster.
