What is caulk called in the UK?

Caulk is called caulk or caulk sealant or decorative caulk in The United Kingdom. And with different types of words all around the world. But most commonly, it is called Caulk or Sealant. 

Origin of caulk: 

The word caulk is derived from the old northern French word Cauquer, which means “to press down.” This seems the product has two reasons to justify this French word as its origin. Such as

  • When using the caulk, you have to press the bottom of the product to make the paste come out of its nozzle. 
  • After you lay down the paste on a particular thing or a place, you have to press it down and spread it on the surface either by using your hands or any other specific tools to make it smooth, common, and seal the cracks or gaps with the caulk paste.

In both ways, you are pressing the product down on the surface, and this word seems to be perfect for this product. 

Where should we use the caulk?

The main purpose of this caulk is to fill the gaps and cracks and opens in the joints of any place, such as wooden things, pipes, glasses, tiles, floors, walls, cement cracks, and more. 

Where should we not use caulk? 

But, you can’t use caulk in wet places like water flowing pipes, especially inside of a pipe, inside water tanks, sinks, and other wet places. 

Advantages and properties of caulk

Caulk is one of the fundamental products that help professionals like carpenters and plumbers correct the mistakes they made that are already done unknowingly during their work, unlike measurements and gaps made accidentally during the process. Example some gaps in the wooden chairs or some gaps while fixing the tiles, etc. Or by some natural causes such as cracks on the walls, pots, pipes, and other places that happen accidentally. 

All these things can be fixed quickly with the help of caulk. 


  • Flexible – Caulk is basically like a paste so, which is liquid and flexible, so, once when it is dried, it generally doesn’t crack with movement. 
  • Water-based – Caulk is a water-based product. So you can smooth it out with a wet finger, and you can even use any other specific tools. 
  • Easy to spread – You can just clean things up with a damp cloth. 
  • Paintable – Unlike Silicone sealants, caulk can be paintable after some hours, or some products claim it can be suitable for paints as soon as it dries. So, It depends on the product and brand that you choose. 

Disadvantages of Caulk

Water-resistant: Once it dries, it can act as a waterproof base. But it doesn’t mean that they can be used around sinks, inside water tanks, and fish tanks. That’s where Silicone sealants play an important role, wherever you want to use sealants to cover up the gaps, especially if it is water-based places like bathing tubs, fish tanks, and around sinks, etc. 

  • Cracks – even though they are used to cover up the cracks, sometimes the product creates some cracks. So sometimes the product needs reapplications to give the best results for long. 
  • Peel off – When we don’t use the product correctly, it can peel off or be removed easily after some time. 
  • Shrinks – we can’t use them in large holes such as nail marks and other huge holes as they shrink themselves and leaves a crack or holes. 
  • Holes – sometimes, caulk also leaves a hole-like space on the surface when you apply them on a nail or a small hole-like pits. That’s why it is requested not to use on a large hole—more than a centimeter. 
  • Lumps – Other caulk products sometimes leave a lump of leakage-like results. Which marks an unfishable look and leaves us to wonder what to do next. Especially when you apply them to small holes. 


The advantages and disadvantages depend on the products that we choose and the raw materials they use to make them as sealants. And sometimes it depends on the budget too. So, always choose them wisely. If you don’t know, it is advised to contact any professional plumber or a carpenter to make sure which product they can suggest to you.
