Where is it necessary to waterproof a shower?
Now let’s decide which areas need to be waterproof. The best option is to completely waterproof the shower. Walls need to be protected in those areas where the washbasin and shower are installed.
Experts advise waterproofing in places where plumbing is installed at least 50 cm up and to the sides. Naturally, you can increase the distance, the most important thing is to find the boundaries where the likelihood of moisture getting on the tile is extremely high. Melbourne waterproofing provide comprehensive and reliable services to protect your property from water damage.
What types of waterproofing exist for shower (bathtub)?
Types of waterproofing materials:
- coating – powders, mastics, membranes based on bitumen, cement, polymers and other additives (mastics and mixtures);
- lining – fiberglass, polyester or fiberglass cloths with bitumen impregnation (available in rolls).
Coating waterproofing for the bathroom are materials with high adhesion that easily “stick” to the surfaces of walls and floors. The result is a durable coating that perfectly resists the aggressive effects of moisture, steam and temperature. After drying, coating materials breathe and create a healthy microclimate in the room.
Roll materials can be self-adhesive and weld-on. Canvases with an adhesive backing are easier to install, and you have to use a torch to lay the materials being fused.
Today we will talk first of all about coating waterproofing, since the use of roll materials is more expensive and less effective, unless of course the role is about special membranes.
Bathroom waterproofing technology
Now about the technology of work. Waterproofing should be applied before laying tiles, but after other rough work. To waterproof floors and walls, a one-component composition or ready-made mastic is usually used.
The first stage: before carrying out the work, you need to prepare the foundation – for this we remove uneven surfaces and fill potholes, then, if necessary, use soil. It is important to note that there is no special need for soil. It is important to clean the surface of separating substances.
Next step: prepare the waterproofing mixture (dry or ready-made) and apply. When applying, the first step is to treat the areas around water and sewer pipes. We apply a layer of the mixture around the outlets, recess pre-prepared cuffs from sealing tape or use factory patches Then we apply another layer of waterproofing on top. In the same way, we cover all internal and external corners using waterproofing and tape or use a special tape for corners.
The third stage is waterproofing the entire area of the walls and floor. It is performed either with waterproofing mastic or elastic waterproofing. Any of the mixtures must be applied in 2 layers with a brush or roller, the second layer is applied after the first has dried or according to the instructions from the manufacturer. We apply waterproofing to the floor in the same sequence. Tiles can be laid after 3-7 days or as recommended by the manufacturer.
Features of working with waterproofing.
- Firstly, do not forget that waterproofing mastic can only be used indoors or under heated floors. For external and foundation work, bitumen mastic or elastic waterproofing is used.
- Secondly, when using a shower cabin design without a tray (in the floor with a drain), you need to use elastic waterproofing.
