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.
 Sewage works and Sunken Portions.

The excellent chemical resistance of Mak Elastothane EMB is used as a barrier coating for any part of the external or internal faces of the structures where high degree of waterproofing is required.

Application Procedure:

1. Clean the surface thoroughly with wire brush, remove all dust, dirt, foreign Particles, fungi, etc.
2. Allow surface to be completely dry. Do not apply Mak Elastothane EMB on damp surface. 3. All the cracks/voids shall be sealed with rubberized Mak Sealing Compound (ISI)
4. Apply Mak Elastothane Primer @ 8-10 Sqm/l on the entire surface to be treated. Alternatively, dilute Mak Elastothane EMB in the ratio of 1:1 with either Xylene or Toluene. Allow the primer to dry.
5. Apply Mak Elastothane EMB by brush or spray @ 1 kg/sqm on the entire surface and upto 300 mm high on parapet wall. Allow it to dry.
6. Apply second coat of Mak Elastothane EMB @ 1 kg/sqm to achieve total dry film thickness of 1.5mm.
7. Reinforcement of Non-woven Polyester or Glass fiber of 40gsm may be provided between the layers for improved tensile strength. 
8. Wearing course should done within 7 days.

Coverage:

Mak Elastothane PU Primer: 8-10 Sqm/l.
Mak Elastothane EMB: 1.2 kg/Sqm on a smooth surface will provide an adequate. film thickness of approx. 1 mm.
*Coverage rates may vary with surface texture and porosity.

Storage:

Store in cool and dry place. Lid of the container should be properly closed after use. In very cold conditions store inside. Do not attempt to thin. Once opened Mak Elastothane EMB will start to cure and a skin will form, even in the resealed cans. This can be removed if material is used within approximately one month.

Health and Safety:

 Keep away from sources of ignition
 Do not breathe vapour/spray
 Ensure good ventilation during application and drying
 In case of eye contact-wash with plenty of clean water and seek medical advice.
 Avoid prolonged skin contact wear suitable protective clothing and gloves while handling/applying.
 Remove from skin with mild solvent/hand cleanser and wash with warm soapy water.

Health and Safety:

For information and advice on the safe handling, storage and disposal of chemical products, users shall refer to the most recent Material Safety Data Sheet containing physical, ecological, toxicological and other safety-related data.

Mak Premix 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.

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.

Usage of Sealing Compound and Primer:

1. MAK PRIMER: The consumption, for 25mm depth of joint would be one litre for 80 running metre length.

2. MAK SEALING COMPOUND GR- ‘A’ IS: 1834- 1984- ISI MARKED

Instructions for Sealing of Joints:

1. Every possible precaution should be taken to ensure that the joints are clean and free from debris and other foreign matter at the time of laying and during the curing process. 2. The primer is applied cold either by a spraying machine or by brush. Primers are inflammable and should not be placed near a named flame.

Construction and Contraction Joints:

In concrete pavements and runways, it is normal practice to provide butt joints with sealing groove 19mm in width at the top in order to facilitate the placing of the concrete. 

Packaging:

Mak Sealing Compounds are available in 20kg, 25kg & 200kg capacity drums.
