Elastomeric Acrylic Waterproofing Membrane
MANTOFLEX is a product composed of water based synthetic polymers. It is a thixotropic paste, easily applicable on horizontal and vertical surfaces. Once dried, it forms an elastic, continuous, waterproofing membrane that is resistant to thermal changes, UV rays, and diluted acid solutions.
Packaging:
MANTOFLEX is supplied in 20 kg plastic containers.
Consumption:
2.2 kg/m² for 1mm thickness.
Storage:
Keep the product at a temperature not less than +5ºC and not more than +30ºC in a tightly closed container. In these conditions MANTOFLEX maintains its characteristics unchanged for 12 months.

Surface treatment
The surface of the concrete to be repaired shall be sound, clean and uncontaminated.
This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter. If the concrete surface is defective or has laitance, it must be cut back to a sound base.
Moss and lichen must be removed physically followed by treatment with fungicidal wash. After treatment, it must be washed down thoroughly with clean water and allow to dry.
Crack treatment
Shrinkages and non-moving structural cracks less than 1.0mm shall be filled with a pre-treatment strip of MANTOFLEX of 1.0mm thick extended to 75 mm on both sides of the crack.
Voids and honeycombs shall be patched with BETOFINISH C or EPOFINISH C allowing the area to cure before applying the membrane.
Right angle bends
All right angle bends must have a coving detail installed. In areas where parapet walls, columns, pipe penetrations are present, a 45° coving fillet shall be made at all corners using BETOCEM FIBER, a Fiber reinforced shrinkage controlled mortar for concrete repair to the water saturated cured surface.
All other angles, joints, protrusions and stress joints should be pre-treated with a heavy application of MANTOFLEX extending 150mm on both sides of the coving.
Allow the patched area to cure before applying the membrane.
Movement Joints
Expansion and movement joints should be sealed with ELASTOSEAL PU25, a Polyurethane sealant. Allow to cure before the application of MANTOFLEX.
Priming
In case of very porous substrates, apply the first coat of MANTOFLEX diluted with 20% of water. Alternatively, apply one coat of PRIMER A 18.
Mixing
MANTOFLEX should be stirred before use until a uniform color and consistency is achieved. Product is ready for use.
Application
MANTOFLEX shall be applied by brush, roller, or airless spray in 2 coats to achieve a minimum dry film thickness of 0.5 mm for each coat. The two coats must be applied at right angles to one another once the first coat dries completely. Substrates that are exposed to movements and deformation or where cracks are expected, reinforcing glass fibre mesh shall be spread into the first coat of MANTOFLEX before applying the second coat.
A layer of ARMOFLEX, a fiber glass sheet should be embedded between the two MANTOFLEX coats over pipe culverts, floor drains, corner joints and floor / wall junctions. It is recommended to spread sufficient clean silica and to the final wet coat of MANTOFLEX before applying tile adhesives. Tiling or finished floor installation should be carried out as soon as possible after full cure of membrane is established.
Cleaning
All tools employed for the application of MANTOFLEX can be cleaned with water before it hardens. Cured materials should be mechanically removed.
Recommendations
n MANTOFLEX is not recommended for use in swimming pools.
n After curing, tiles and flags can be laid over the applied MANTOFLEX layer on vertical and horizontal areas using an appropriate specified adhesive from COLMEF’S NEOFIL range.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water an again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
