1. Mixing : Sprinkle the mortar over the water maintaining a water/product ratio of approximately 0.50 (around 9 liters per 20 kg bag). Let the product moisturize before mixing.
2. Beating : Once moistened, beat the mixture using a mechanical procedure until the paste is homogenized. It is important not to add additional products or additives, as they can alter the characteristics and results of the mortar.


1. Preparation of the Support: Make sure the surface is free of dust and oil stains. In absorbent supports, it is advisable to moisten them with water to avoid rapid dehydration of the mortar. If the support is very absorbent, a light primer can be applied.
2. Laying the Mortar: Apply the Wulmek Base B7 mortar on the support using a trowel, spreading the necessary amount until the desired thickness is reached.
3. Hardening and Closing: Once the mortar reaches its hardness point, reworking begins to smooth and close the surface using the chosen finishing method. You can also use the same Base B7 for the finishing review with greater surface hardness.

Post-Application Care:

Avoid applying the product in extreme temperature conditions (below 3°C or above 40°C) to ensure proper curing and adhesion.
