PVM omnifix
Construction adhesives
Adhesive mortar for all brick types.
Characteristic product properties
- Suitable for all brick types and small natural stone blocks.
- More intense façade colour due to narrow recessed joints (3 - 6 mm).
- 4 times more resistant, greater moisture resistance and efflorescence-arm.
- Fiber reinforced.
- 3 types: A (highly porous bricks), B (moderately porous bricks) and C (low porosity bricks).
Applications
Suitable for all kinds of brick façades on internal and external walls. Narrow beds and vertical joints give your brick wall, façade, balcony or column a contemporary look. Narrow joints, combined with highly moisture-resistant bricks and the fiber reinforced adhesive mortar, make it possible to create façades with open vertical joints. Using an adhesive mortar of the same colour and recessed joints means that the adhesive can hardly be seen. This enables you to obtain a façade with intense colours that make the bricks look even better. Three types of adhesive mortar are available as standard versions (A, B or C), so that you can apply bricks with different water absorption coefficients equally quickly and
under a variety of conditions.
This fiber reinforced adhesive mortar has superior physical qualities, such as frost resistance, deformation capacity, adhesion and bending tensile strength. For example, high adhesion and bending tensile strength values mean that PVM omnifix can be used to make prefabricated components and corner pieces. Apart from the possible appearance of soluble salts in the bricks, this product guarantees that your façade will keep its intense colour.

What is the difference between the techniques?
Gluing/thin bricklaying, ironing and normal bricklaying of facing bricks.
- Gluing or thin brickwork: a joint of 4 to 8 mm is created between the facing bricks. The glue or thin-bed mortar (also called thin-bed mortar) is applied recessed (deeper) and the stone is no longer added. Because a thinner joint is created that is not added, the color of the stone largely determines the appearance of the facade. The adhesive mortar or thin-bed mortar is often processed in a color that matches the stone color.
- Traditional masonry: The joint is approximately 12 mm. When laying bricks, the joint determines the appearance. The thinner the joint, the stronger the effect.
- Flushing: This technique involves traditional bricklaying (8-12 mm joint) whereby the colored masonry mortar is also used to finish the joint in one subsequent work pass. It mainly increases returns.
The choice between gluing and thin bricklaying on the one hand and bricklaying or ironing on the other hand is primarily an aesthetic choice.
Is there a chance of efflorescence?
Everyone is familiar with the white or gray rash on masonry. Annoying and not aesthetically pleasing. There are different types of efflorescence: saltpetre, lime efflorescence and gypsum efflorescence. With the use of Omnicol adhesive and thin-bed mortars, the phenomenon of efflorescence on the facade is greatly reduced compared to standard masonry. Always ensure that the guidelines regarding the protection of fresh masonry are adhered to. Do not process mortar at very low temperatures (< 5°C) or during rainfall. In addition, the choice of facing brick is also an important factor in preventing the risk of efflorescence.
Do I have to order my colored mortar in one go?
It is advisable to order colored mortar in one go to avoid slight color differences.
