Nurcoat
Rubberized Bitumen Coating
Nurcoat is a single component high performance waterproofing membrane with high elasticity and low water permeability. Nurcoat is an emulsified rubber modified bitumen coating, which dries to form a tough, seamless, flexible vapor proof protective coating. Nurcoat R10 conforms to the requirement of ASTMD 1227 Type lll.
Advantages of Nurcoat
- Cold applied, no heating required
- Forms elastomeric membrane
- Reduced chloride penetrations due to hard impermeable surface
- Multipurpose, serves both as a protective coating and curing membrane
- Environmentally friendly. Contains no Solvents, no health hazards
- Asbestos free, odorless. Can be applied in closed and confined spaces.
- Easy application due to paintable consistency, suitable for new and old concrete.

Typical Application
Can be used for a wide variety of applications, like protective coating on concrete foundations, curing compound on freshly cast concrete structures, damp proof membrane in sandwich constructions , vapor proof barrier coating for interior & exterior floors & walls.
Application
- Agitate the drum before use. The drum should be rolled on the ground back and forth before decanting material.
- Apply by brush or roller. Two or more coats must be applied to ensure a durable finish. Second and subsequent coats should be applied at right angles to each other once previous coat have fully cured, allow min 24 hours between first and second coat for better curing.
- Nurcoat R10 can be applied to damp but not water clogged surfaces, dampen the brush before and occasionally during use, for smoother application.
- Note: The applied coatings of Nurcoat R10 require full cure before it undergo flood test. To achieve full cure will take 6-7 days, subject to favorable moisture, temperature and ventilation conditions in the location.
Features
Surface Preparation
The surface shall be cleaned thoroughly of all contaminants
like dust, traces of curing compound,
oil and grease. Light mechanical grinding/grit blasting/high pressure water
jet may be used to
clean the surface of all the contaminants depending on the degree of
contamination on the
surface to be coated. All surface imperfections and protrusions shall be
removed and repaired.
Structurally unsound and friable concrete must be removed and repaired
Priming
It is highly recommended to apply a priming coat prior to the
application of the NURCOAT R10
coating on the substrate. The primer can be prepared in the site by diluting
NURCOAT R10 with
20% water and applying this diluted coat as the primer. The primer can be
applied to damp or
freshly cast concrete surfaces. For very dry and porous substrates apply two
coats of this primer.
However, it should not be applied on waterlogged or flowing water areas.
Further coats shall be
applied only after the primer coat dries off completely. In case of delay in
application of the top
coat for more than 24 hours, a fresh coat of primer shall be re-applied.
Coverage
Apply the coating at a coverage rate of 1-3 m2/Lt, depending
on the dry film thickness required. 300micron dry film thickness (DFT) can
be achieved when applied at 3m2/Liter/Coat.
Health & Safety
It is non-hazardous and non-flammable emulsion. Harmful if
taken internally avoids contact skin and eyes. In case of accidental contact
with eyes, wash with copious amount
of water and seek medical attention. Wear gloves and goggles.
Remarks
Empty cans should be disposed as per the rules and regulations
of the country where
the material is used. And in NO case should empty cans be used for food
stuffing.
