Do you dream of a bathroom that not only impresses aesthetically, but also stands the test of time? The key to durability is well executed waterproofing. In this step-by-step article, we'll show you how to waterproof your bathroom - effectively, without stress and without costly fixes. In Water Block you will find the best materiles and advice to help you achieve a lasting result - check out how to do it.

Why is waterproofing the bathroom so important?

Moisture in the bathroom is not just steam on the mirror. It's a constant threat to the durability of the structure, as well as to your health. Proper waterproofing protects walls and floors from mould, fungi and cracks. At Water Block, we know how important quality is - that's why we offer you solutions that are proven, effective and tailored to the type of room.

  • Wet zones is not just the shower cubicle - it also includes the floor, the area around the wash basin, the toilet bowl, the bathtub and the washing machine.
    Ceramic tiles are not enough - There should always be a waterproofing layer underneath.
  • Invisible leaks can destroy the entire structure of the bathroom - which is why it is so important to carefully protect corners and plumbing penetrations.

In our experience, the most common mistakes are due to a lack of knowledge about moisture load classes and inadequate selection of m1TP2Bodies. And yet you can avoid this. At Water Block we will advise you on which system will work best.

Moisture load classes - what do you need to know?

The first step to well executed insulation is to determine what type of moisture you are dealing with. Class I refers to when water enters the drain through the shower tray - this is the case in classic shower enclosures. Class II is more challenging - this refers to so-called walk-in showers with an in-line drain, where the water runs directly down the floor surface.

Depending on the load class, different materiles are used. At Water Block, we will advise you exactly which products will work for your project. It is not only about tightness, but also durability and resistance to deformation.

How do I waterproof a shower cubicle without a shower tray?

Insulating a shower without a shower tray is one of the basic tasks when renovating a bathroom. This type of solution is modern and aesthetically pleasing, but requires a special approach. In order to do the waterproofing correctly, a slope must be used to allow the water to drain into the grating and the right m1TP2Insulation materials must be used, such as:

What are the steps to waterproofing a shower?

  1. Substrate preparation: Level the surface, clean off any impurities and prime with WB Primer.
  2. Seal corners and joints: Apply sealing tape to all corners and joints with the linear drain WB Tape Pro. Also seal plumbing penetrations and plasterboard joints with tape.
  3. Applying the first layer of insulation: Thoroughly mix WB Duo Flex insulation and apply the first layer (approximately 1-2 mm) with a brush or trowel.
  4. Application of insulation mat: On the horizontal surface, sink the WB Membrane insulation mat into the WB Duo Flex insulation.
  5. Application of the second insulation layer: After the first layer has dried, apply a second final layer of WB Duo Flex insulation.
  6. Installation of tile cladding: After approximately 24 hours, tiles can be installed.

By carrying out proper waterproofing of the bathroom, there is less risk of renovations related to moisture damage. Damp proofing reduces damp patches and prevents conditions conducive to the growth of fungi and mould.

How much does it cost to waterproof a bathroom?

The cost of waterproofing a bathroom can vary depending on the size of the room and the m1TP2Materials used. Examples of m1TP2Bodies prices:

  • WB Duo Flex 10 kg: approximately £270.
  • WB Tape Pro: approximately £188.
  • WB Membrane: approximately £418.
  • WB Primer Primer 2L: approximately PLN 55.

Waterproofing the bathroom is essential to protect the building structure from moisture, prevent mould and mildew, and ensure the long-term durability and aesthetics of the room.

How to waterproof a bathtub properly?

Waterproofing a bathtub requires similar m1TP2Materials and techniques as for a shower. The use of WB Tape Pro and WB matting ensures waterproofing is tight and durable. It is important to take special care of corners and joints where moisture can most easily penetrate.

In summary, waterproofing a bathroom is an essential element that ensures the durability and safety of the room, protecting it from the damaging effects of moisture. With the right m1TP2Materials and techniques, you can avoid costly renovations and enjoy a beautiful, functional bathroom for years to come.

How to waterproof a bathroom step by step?

Waterproofing a bathroom is a process that requires thoroughness, but it does not have to be difficult. The key is to follow the steps and use quality products. At Water Block, we offer you comprehensive waterproofing systems and expert advice so that you can carry out the waterproofing yourself or with the help of a professional.

First, clean the substrate thoroughly - remove dust, grease and residues of old mortar. Prime the surface with a primer and then seal all corners and pipe penetrations with tapes and cuffs. Only then do you apply the liquid foil or mineral grout - in two layers, crosswise.

Ensure that the surface is dry before proceeding to the next steps. After 10-12 hours you can lay the tiles.

Steps for waterproofing a bathroom:

  • Substrate preparation - remove any residual mortar, level the surface and check its load-bearing capacity.
  • Priming - protect absorbent substrates with a suitable primer.
  • Sealing of corners and penetrations - insert sealing tapes and cuffs at critical points.
  • Slurry application - Apply two coats of the product, a few hours apart.

Remember - the quality of the mater materials and the accuracy of the workmanship have a direct impact on the durability of your bathroom. We at Water Block make sure that you have access to the best and proven solutions.

What should I pay particular attention to when applying?

When applying waterproofing, the most important thing is to maintain full surface coverage. Any break or inaccuracy can result in later leaks. Don't forget to seal floor-to-wall joints and plumbing penetrations - these are the most common points of failure.

In areas particularly exposed to water, we recommend the use of mineral sealing mortars. In Water Block you will find products suitable for every type of substrate - from cement plaster to gypsum blocks.

This gives you the assurance that your bathroom is protected comprehensively and for years to come.

Tiling after waterproofing

Once the waterproofing layer has dried completely, you can start laying the tiles. Use a flexible adhesive mortar that will ensure adequate adhesion and stress compensation. At Water Block, we will help you choose the right adhesive depending on the size and type of tiles.

Don't forget to cover the surface properly - the larger the tile, the more important it is that the adhesive is also on the underside of the tile. Use spacer crosses and a spirit level to maintain correct spacing and plumbness.

Well laid tiles are not only a question of aesthetics, but also of tightness.

Grouting and finishing - the final step

You can start grouting 24 hours after laying the tiles. Choose a grout that is resistant to moisture and fungi. Keep the joints clean and dry - this guarantees their durability.

Remove excess mortar with a damp sponge after grouting and with a dry cloth after it has set. Fill the wall and wall-to-floor junctions with flexible sanitary silicone. Thanks to these steps, your bathroom will not only be aesthetically pleasing, but above all durable and safe to use.
