Two Component Elastomeric Cementitious Waterproofing Coating
MANTOBRUSH is a two component, cementitious acrylic modified waterproofing coating. It is composed of special types of cements, silica sand, reactive fillers (powder), and acrylic polymer blended with chemical additives (liquid). Once mixed, it produces a workable, easy to apply, product that can be applied with brush or spatula.
MANTOBRUSH provides a seamless, hard wearing, flexible waterproofing membrane with excellent adhesion to the surface.
MANTOBRUSH is supplied in a pack of 28 Kg Kit.
Consumption: 1.5 kg /m² per 1 mm thick coat depending on surface conditions.

MANTOBRUSH is supplied in pre-measured quantities. Start mixing the product by adding the powder to the liquid and mix using slow speed mixer. Mix for about 4 minutes.
The mixture should be placed immediately after mixing. Mix enough material that can be applied within the pot life time.
It is advised to apply MANTOBRUSH in two crossed coats of 2 mm total thickness. The second coat should be applied once the previous one has dried.
In case of using fibre glass mesh reinforcement, apply the first coat with 2mm thick. Place the reinforcing non-woven fabric on the first coat while it is still fresh. Apply the second coat within 24 hours. Apply an extra coat on corners and around rain or drain outlets.
Tools and equipment should be cleaned with water immediately after use.
Concrete must be solid, clean, free from oil, grease, dirt and paints. The surface can be prepared mechanically using sand blasting for large areas or steel brush for small areas.
Curing compounds or shuttering oils should be completely cleaned out.
Damaged concrete should be repaired with a suitable cementitious repair mortar. Pinholes should be widened, cleaned and filled.
Prior to application the surface should be soaked with clean water. Excess standing water must be removed.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment. Avoid inhalation of vapours.
In case of contact with skin, rinse with water and 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.
