What is the best way to waterproof a bathroom?
A bathroom is a room whose microclimate is significantly different from all other living spaces. It is characterized by regular changes in air temperature, high humidity levels, as well as the formation of condensation on walls and surfaces. Most often, the walls of bathrooms are concrete or brick partitions with a finely cellular porous structure. Such surfaces must be protected from moisture to prevent their destruction.
Any kind of finishing materials has an individual level of moisture saturation and moisture loss. Regular operation of the bathroom is accompanied by an increase in humidity, which means that water, steam and condensate seep through the interlayer seams into the tile itself and under it. Despite the fact that this process can drag on for years without visible changes, after some time the finish is completely saturated with moisture and the process of its destruction begins. That is why you should think about high-quality waterproofing of the bathroom.
What to choose?Not so long ago, waterproofing was carried out with bitumen, but thanks to modern developments, we have the opportunity to use more efficient, resistant and easy-to-use materials.
Special attention should be paid to the coating mixtures, which are applied no more difficult than paint and at the same time have excellent technical characteristics. We recommend paying special attention to the Teknomer 300. This is an acrylic one-component polymer-based waterproofing compound that has excellent elasticity and performance properties.
Why you should use Teknomer 300 to protect the bathroom from moistureTeknomer 300 acrylic mixture is highly resistant to heat, does not allow steam, water and condensate to penetrate the walls, and is also immune to temperature changes.
Working with a single-component mixture is very simple and it does not require special skills. It can be applied immediately from the package, so Teknomer 300 is great for waterproofing the bathroom with your own hands.
Among other advantages of the mixture , it should be noted:High degree of adhesion
- No cracking after drying or prolonged use
- Easy application with a roller or flat brush
- The mastic-insulated surface can be tiled and painted
- Drying of the layer takes only 5 hours.
With a thickness of 1 mm, the Teknomer 300 waterproofing consumption is 1.53 kg/m2. A bucket of 20 kg when applied in two layers is enough for waterproofing a surface area of 6.5 m2.
