Mak Premix Superior is an instant road repair compound which is manufactured with a blend of bitumen, aggregates and high grade polymers to ensure immediate bonding with existing surface. Repair of heavily trafficked road and airfield pavements using conventional materials and procedures is difficult, inconvenient to user and generally not very satisfactory. For such locations, ready to use patching materials to up- keep pavement traffic worthy, are essential.

Mak Premix Superior is specialised road patching product with high bitumen content >8% specially designed for long life and flexibility.

Mak Kote is an emulsion of selected grade of Bitumen with Fibre and Fillers.

It acts as a low cost alternative to solvent based primer and acts as a waterproofing layer in itself.

Mak Elastothane EMB is a liquid applied polyurethane modified bituminous elastomeric membrane coating. Mak Elastothane EMB when applied on a surface, gives a continuous monolithic film which is rubbery and elastic in nature. The film is self-curing and cures by reaction with atmospheric moisture to give a tough elastomeric waterproof membrane.

Mak Elastothane EMB has good adhesion to a wide range of substrates such as concrete, brick, wood, slates, tiles, glass and metals etc. This is supplied also as a medium grade for roller, squeegee or brush application to horizontal as well as vertical surface.

Area of Application:

The high elasticity, excellent bond strength with concrete and other substrates, low water permeability of Mak Elastothane EMB makes it ideal membrane coating for a wide range of water / vapour proofing applications such as.

 Foundations, Basements, Lift pits.
 Car decks, Podiums.
 Roof, terraces, Balconies, Patios.

A Joint Sealing Compound must display good adhesion towards concrete and has the ability to withstand extension without cracking. It must also have a low susceptibility to flow during hot weather conditions.

It should be durable and plastic, and at the same time offer resistance to ingress of solid foreign matter.

The Joint Sealing Compound is heated to temperature which will permit easy pouring into the expansion joint above the joint filler. This temperature should be well below that at which Joint Sealing Compound undergoes decomposition and should not exceed temperature as specified against each grade of sealing compound. 

1. MAK SEALING COMPOUND: GRADE A- IS 1834/1984.

It is an ideal hot pour Sealing Compound specially rubberised to withstand cracking besides having good adhesion to concrete it is also durable and is not affected by temperature changes. It has working temperature of 175???C - 185???C and a density of 1020 kg per cubic metre.

2. MAK SEALING COMPOUND: GRADE B - IS 1834/1984.

It is unaffected by petrol spillage especially jet fuel. It is therefore recommended for use in garages, filling stations etc., where there is spillage of petrol, oil and grease. It has a working temperature of 155???C- 165???C and a density of 1200 kg per cubic metre. On application of this product Mak Jet Primer is to be applied by brush or spray to ensure for proper adhesion. Care should be taken to see that Primer has sufficiently dried prior to pouring of Mak Sealing Compound into the Joint.

Mak Crete MWP is an acrylic based polymer modified cementitious water proofing system. The MAK CRETE polymer, when mixed with cement will provide the unique solution to all problems related to water leakage and protects from severe fungus, salt penetration, or environmental attack in the following structures:

• Roof Slab, Parapet, Terrace, Balconies.
• Basements, Retaining Walls, tunnels, etc.
• Bathroom and any floor to dampness
• Against corrosion and salt attacks
• Water Tanks or swimming pools
• General concrete repair

When mix with the cement, it will provide better adhesive properties, impact resistance, flexural strength, and thin section fragility when compared with ordinary cement mortar. 

PRODUCT FEATURES

• Mak Crete MWP increases the plasticity of concrete and cement.
• Provided a tough and hard surface with water proofing.
• Resistant to salt penetration
• Resistant to UV rays, mild acids to strong alkalis.
• Non-Flammable.
• No health hazards to workmen.
• Can be applied on horizontal as well as vertical surfaces. 

HOW IT WORKS

It is well accepted fact that the damage skin or flesh of human body is only replaced with the skin or flesh of similar body. Likewise, damaged cementitious concrete or mortar should always be replaced by same kind of material. But cement particularly is having poor adhesive properties, low flexural and impact strength and mainly thin section fragility. Addition of acrylic polymer MAKCRETE into cement acts as a bonding agent and forms a hard, impermeable film which prevents not only water and fume but also allow the structure to breathe. This film, unlike all other existing conventional materials is flexible enough to take care of the thermal movement of structure and protects from severe attacks during all seasons. 

SURFACE PREPARATION

The area to be coated must be sound clean, and free from oils, grease, or any other surface contaminants. Remove any loose material by scraping, chipping, mechanical abrasion, or any other suitable method. Visible cracks or any porous substrate are to be filled or levelled by using filler. The prepared surface is to be adequately saturated with water for atleast one hour before application, but leave no puddle of water. Cleaning of salt attacked area can be thoroughly washed muretic acid followed by copious water till neutral to litmus. Excellent surface preparation will ensure superior water proofing, excellent bonding & economic coverage.

MIXING

Take 1 part by weight of MAK CRETE into a clean container and then add gradually 2 parts by weight of fresh cement under continuous mixing till a lump free pintable consistency is achieved. NEVER ADD LIQUID INTO THE CEMENT.

APPLICATION

The slurry made by the above method is to be applied by a wide flat brush or broom across the prepared area uniformly. Apply the second coat of the freshly mixed slurry soon after the first coat is air dried sufficiently (Normally 3 to 6 hours). Stir frequently during use to offset settlement. NEVER USE A PREPARED SLURRY MORE THAN 30 MINUTES OLD.

CURING

MAK CRETE composite slurry system does not require continuous wet curing or ponding but it is recommended only after 24 hours of final coat application sprinkling of water or a cover with a plastic sheet to minimize.
