Things You Need to Know When Applying Sealant – A Homeowners Guide

Have you recently had a new bath fitted? Or are you looking to replace some old sealant that has started to peel?

It may seem simple, but applying sealant is more complicated than you may think. You have to take care not to damage the bath surface or the tiles while also making sure that the end result looks good.

So, if you are up for a bit of DIY, read on for a quick guide on how to apply sealant in your bathroom.

Step 1- Tape Off the Edges

Firstly, as any professional mastic man Essex will tell you, if you are looking to seal a bath or sink, you can start by adding masking tape both above and below the area you want to seal. This isn’t an essential step, but it will help the application of the sealant to be more accurate and will also protect the surface of your bath and tiles.

Step 2- Fill the Bath

Next, you need to fill the bath with water. This will help you to assess how much sealant you need and will prevent it from cracking when the bath is being used post-sealing.

Step 3- Open the Sealant and Put It in a Gun

You will usually need a sealant gun to make sure that the sealant is applied correctly. Open the sealant and cut the tip at a 45-degree angle. This will help with a more accurate application.

Step 4- Apply the Sealant

To get a good finish with the sealant, you need to apply it in one smooth step. So, the best tip is to start in one corner and move to the other, squeezing the gun trigger as you go.

Try to keep the pressure even when you are applying the sealant, or it may come out thicker on one part of the bath or sink than another, which could lead to future cracking or peeling.

Step 5- Smooth the Sealant

When you are happy that the sealant has been applied correctly, the next thing to do is to smooth it. You can use a smoothing tool to do this, or you can simply wet your finger and smooth it over the area. Try to ensure that you smooth the sealant evenly and at an angle so that if water hits it from the shower, it will allow it to drain rather than form pools.

Step 6- Let It Set

Well done! Your sealant is set and looks great!

Now, to keep it in place and functioning, you will need to let it rest for 24 hours. However, if you have chosen a quick set sealant, you may be able to let it rest for 12. Just make sure that you don’t get it wet and don’t put any unnecessary pressure on it. When it is setting, make sure you don’t empty the bath, as this can cause it to set at an odd angle and can lead to an uneven finish.
