MISCONCEPTIONS ABOUT MIXING WATERPROOFING MATERIALS - WRONG MIXING RATIO WILL DAMAGE THE WHOLE PROJECT

1. Why is mixing ratio important in waterproofing?

Many construction teams today mix waterproofing based on experience, "estimate by eye", and do not follow the correct ratio given by the manufacturer. Consequences:

- Too thick to adhere to the surface.

- Too thin leads to reverse osmosis and easy to peel off after a few months.

- Mixing in the wrong order causes the glue to clump and lose its adhesive ability.

The ratio of mixing the waterproofing layer is not a matter of emotion - it is a matter of technique.

2. Common misconceptions when mixing waterproofing materials

- The thicker the glue, the stronger it is: The truth is that glue that is too thick does not penetrate deeply into the concrete capillaries, creating a weak film that peels off easily.

- Just stir well: If you do not use the mixer at the right speed - the glue will clump and the chemical reaction will not be complete.

- Mixing glue first, water later or vice versa is the same: In fact, the wrong order can break the bonding structure, affecting the durability of the coating.

2. Waterproofing materials often have to be mixed

- 2-component cement base (eg Sikatop Seal 107, 109,...).

- PU and epoxy based glue - requires accuracy to the nearest percent.

- Adhesive agent mixed with oil paste.

3. Mixing waterproofing glue properly – The key to sustainable construction

- Read the technical instructions from the manufacturer carefully.

- Use a scale or measuring cup for the most accurate measurement.

- Use a mixer at medium speed to ensure even mixing.

- Mix each batch just enough within the allowed construction time.

Practical example: With 2-component cement-polymer materials, such as Sikatop Seal 107, it is necessary to mix in the correct ratio, mixing time 3-5 minutes, rest for 1 minute and then mix for another 1-2 minutes before construction.

4. Waterproofing is not just about “covering” – it is science and technology.

- A 10-15 year durable waterproofing project requires precision from the beginning: cleaning the surface, treating the joints, choosing the right materials, mixing in the right proportions, applying enough layers, and waiting for the right amount of time. In particular, the waterproofing mixing ratio is the key to determining the final quality.

- Don't let careless habits ruin the waterproofing layer: Mixing the wrong materials will ruin it, no matter how expensive it is, it's useless.
