Waterproofing a Wet Room with WT1

Wet rooms are usually damp and need to be waterproofed. This is referred to as tanking. It’s the process of creating a waterproof barrier between tiles and the wall itself. Knowing how to waterproof a wet room is a valuable life lesson. You can save yourself a lot of time, energy and money by waterproofing your wet room with WT1.

Taking wet rooms such as bathrooms and swimming pools etc. isn’t as difficult as it seems. Whilst tiles and waterproof boards are water resistant, you need to be completely confident that the joints in between tiles are 100% waterproof too. If they aren’t, there is a high chance of leaks occurring as a result. Leaking tiles and walls etc. can damage your walls, floors and the fabric of your building. There is also the major concern of weakening the structure of the wet room, which is extremely problematic when situated above the ground floor.

Prep Work

It’s important to clean debris before applying your waterproof membrane. To do this, take a blade and etch larger clumps off the surface of the wall. Once you have tackled those sections, you need to ensure the base is free from dust and grease. Take a trusted bottle of Multisolve and spray this solution onto the desired area. Multisolve will work its unique formula into the substances and uses a gentle, safe and effective method to detach it from the surface. You can also use Multisolve to smooth joints after applying your sealant.

Applying WT1

For a job like waterproofing your bathroom, you’ll need to get your hands on a waterproof sealant such as WT1. As the ultimate replacement for bitumen based roof membranes, WT1 provides an excellent adhesion to most materials, particularly those often used in construction works such as leads, metals, plastics, concrete, brick, polyester and stone.

One of the main concerns that arises when tanking wet rooms, is the fear that the silicone sealant will shrink or crack over time. However, WT1 refuses to shrink or crack. It is water resistant and adds an extra layer of waterproof protection to your bathroom walls and floors. You can also use WT1 with other products from C-TEC such as CT1, Multisolve and Power Grab ‘n’ Bond. This means you can waterproof your bathroom with WT1 and attach suitable substrates such as tiles or decking products etc.
