How to Choose a Sealant in the UK - Buying Guide

The main use for a sealant is to create a waterproof seal around an area, so our buying guide will take you through which sealants are best for the different parts of your home. We’ll take a little look at their make up and give a few suggestions about what works best where.

Pick a Sealant Branded for the Job You Have in Mind

Pick a Sealant Branded for the Job You Have in Mind

If you’re reading an article on silicone sealants, you probably have a job in mind and need the right product to match. Luckily, most sealants are branded in a way that it is clear what job it is suitable for. If you're set on re-doing your sinks and shower, for instance, looking out for a “Bath & Kitchen Sealant” or a “Showerproof Bathroom Silicone” will serve you well.


You’ll also see many general-purpose sealants, which are a brilliant choice to have handy around the house for maintenance and odd jobs. Great for use inside or outside the home, it's always useful to have a couple of tubes in a cupboard somewhere for when you need to quickly patch something up.

Understand the Difference Between Silicone and Acrylic Caulk

Understand the Difference Between Silicone and Acrylic Caulk

Most of the sealants you will find on the market today are made up of silicone polymers and cure to make a strong, flexible rubber, creating a good waterproof seal. These are stronger, more flexible and longer-lasting than their acrylic siblings. 


Acrylic sealants, or caulk as they're sometimes known, are usually a cheaper alternative and can be painted on without any issue. If you have a lot of ground to cover and are working on a budget, acrylic can be a good option, but silicone really is better in almost every other way.


The third category of sealant is the hybrid, usually made up of a blend of silicone and other polymers. These tend to combine the strengths of all materials, creating a high-performing and weatherproof fusion, but often come at an increased price point.

Many Sealants Will Have a Few Extra Features That Are Worth Looking Out For

Many Sealants Will Have a Few Extra Features That Are Worth Looking Out For

While many sealants are branded in ways to help point you towards what they're suitable for, it's worth knowing that this is because they usually have special properties. One example is anti-mould or sanitary formulas, which contain fungicides to prevent mould from forming on the silicone – a must-have for areas with a lot of moisture, like bathrooms and kitchens.


Another one to look out for is a quick-drying formula, which can become safe to touch or splash pass water over in a matter of minutes. When it comes to industrial sealants, some can take days to properly cure, but most aimed at home use won't take anywhere near as long.

Many Sealants Will Have a Few Extra Features That Are Worth Looking Out For

If you're working with fridges or freezers, it's worth making sure your sealant is food-friendly to ensure that it's not toxic when coming into contact with food. There are countless other examples, but most are fairly self explanatory and do exactly what they say on the tube!


It's also worth noting that to use most sealants you will need a sealant gun, which is a device that the tubes slip into to squeeze out the silicone. There are some products, usually smaller ones, that don't require any other accessories as you're able to squeeze the tube like glue or toothpaste.

Make Sure You Have Enough Sealant to Finish Your Job

Make Sure You Have Enough Sealant to Finish Your Job

It can be difficult to determine how much sealant you will need for a particular job, but it’s important that you have enough because once you start you need to make sure you’re finished with a section before it begins to cure. Luckily, a lot of sealants are relatively inexpensive, so it’s just a case of picking up a couple of extra tubes.


Measuring the size of the tube against the length of the area you’re sealing will give you some idea of how much you’ll need, but you should also consider the width and depth of the joint as well. Most tubes are around 300 ml and should last around 8 meters for an average joint.

White Is the Most Common Colour, but Look for Clear Formulas if Working With Glass

White Is the Most Common Colour, but Look for Clear Formulas if Working With Glass

While you won’t find a rainbow of different colours in the sealant world, there is a choice to be made when it comes to which shade of silicone to opt for. White is by far the most common and has the most applications, but it’s also easy enough to find black and grey options if you want them.


You can also get clear silicone, which is transparent. This makes for a perfect choice when working with glass or clear plastics. Keep in mind that you can’t paint silicone, so once you’ve made your choice you’ll be stuck with whatever colour you decided for a while.

Top 10 Best Sealants in the UK

Now that you've had a chance to look through the different types of sealant on the market and thought about what would work best for the job you have in mind, it's time to take a look at our top 10 list. Whatever you opt for, you can trust that you're buying a highly-rated, quality product.
