BAUCOAT HP
Elastomeric Waterproof & Protective Coating Based
on Polyurethane Dispersion (PUD)
DESCRIPTION
BAUCOAT HP is a liquid applied elastomeric
waterproof and protective coating based on
polyurethane dispersion (PUD)
The polyurethane is modified with specially
selected polymers to form a tough, flexible and
durable coating. It is completely free of
hazardous ingredients.
TYPICAL USES
Waterproofing or vapor barrier protection of
exposed roofs, domes, terraces, balconies,
corrugated sheets and wet areas like kitchens,
bathrooms & toilets
ADVANTAGES

dirt pick-up.
• Excellent crack bridging properties
• Exhibits high resistance to weather
conditions and good resistance to UV
radiation
• Good adhesion and elastic recovery.
Excellent resistance to water and vapor.

APPLICATION INSTRUCTION
Surface Preparation
Surfaces must be cleaned and made free of dust,
dirt, moss, oil, grease and other loose particles.
This can be achieved by grit/sand/shot blasting.
As a minimum, vigorous wire brushing should be
employed. All pin holes and surface defects shall
be repaired with a suitable concrete repair
mortar.
Priming
BAUCOAT HP does not require priming as such
and can directly be applied onto the substrate
surface. In case of highly porous surface, a
priming coat is recommended to seal the pores
and stabilize the surface.
The primer coat can be produced on site by
diluting BAUCOAT HP with water (20% by
weight) . Apply the primer coat @ 4m²/ Kg and
allow to dry.
The primer coat also functions as an adhesion
promoter for the top coats. It can be applied by
a brush, roller or airless spray and allowed to dry
completely before the application of subsequent
coats.
Mixing
BAUCOAT HP is a single component product but
mix the contents of the pail thoroughly prior to
application to remove any sediment. A slow
speed drill and suitable paddle mixer shall be
used to avoid the formation of air bubbles.
Application
The coating can be applied with a brush, roller or
airless spray and shall be applied in a minimum
of 2 coats. Apply the first coat of undiluted
material at a coverage rate of 1kg/m2
/coat to
get an approximate dry film thickness of 0.5 mm.
It is important to ensure that each coat is
completely cured before applying subsequent
coats. The second coat should be applied at right
angle to the first at the same coverage rate, to
ensure a full unbroken coating to the substrate.
CURING
BAUCOAT HP will achieve its full strength after a
curing period of 7 days.
PACKAGING
25 Kg Pails & 200 Kg Drum
COVERAGE
1Kg /m² at 0.5 mm thickness.
Two coats will give a combined thickness of 1mm
STORAGE & SHELF LIFE
Store under cover, out of direct sunlight, clear of
the ground on pallets and protect from extreme
temperatures. In tropical climate the product
must be stored in air-conditioned environment
(<25ºC).
Shelf life is 12 months when stored as above.
PRECAUTIONS
As with all construction chemicals products
caution should always be exercised. Protective
clothing such as gloves and goggles shall be
worn.
Treat any splashes to the skin or eyes with fresh
water immediately. Should any of the products
be accidentally swallowed, do not induce
vomiting, but call for medical assistance
immediately. There are no known health hazards
associated with BAUCOAT HP.
Clean all the tools with water after use.
Hardened materials can be removed
mechanically only. Allow the waste to cure. Seal
it into a suitable container and bury in landfill as
per local regulations.
BAUCOAT HP
Highly Elastomeric Acrylic Waterproofing & Protective Coating
1. Product Description
BAUCOAT HP is single component highly elastomeric, acrylic waterproofing and
protective coating.
2. Substrate Requirement
• All surfaces must be structurally sound, clean, free from dust, oil and any traces of
foreign materials that may affect adhesion of the waterproof coating on the
substrate. •
• Brick, block and concrete walls/ floors must be allowed to cure for a minimum of 4
weeks prior to application of BAUCOAT HP.
• Cement render and screed must be allowed to cure for at least 7 days and finished
to semi-smooth finish with a wood float. After curing, a thorough check on the
soundness in adhesion of the screed and render should be carried out. All
substrate defects should be properly rectified.
• Painted surface must be scrapped to expose the original substrate for the
waterproofing application.
• The trueness of the background surface required for the substrate beds should be
such that, when checked with a 2m straightedge, any gap under the straightedge
between points of contact does not exceed 3mm.
• Thoroughly dampen the substrate with water and allow access to drain away.
• Incase of metal substrate, rust scales to be removed using wire brush.
• Ensue a minimum slope of 1 in 100 is already provided
3. Application of BAUCOAT HP
• Make sure that all substrate requirements are met, such as temperature, moisture
content of the prepared substrate (preferably below 5%) etc.
• Mix the bucket/drum thoroughly prior to application to remove the sediments.
• Dilute BAUCOAT HP with 20% water to be used as primer coat on the substrate
and allow it to dry for about 3-4 hours.
• Once the surface is dry, clean the surface and apply BAUCOAT HP at 1 kg per
square meter. For spray application, dilute BAUCOAT HP with 5% of water to
reduce the viscosity.
• Allow the surface to dry for 4-5 hours.
• Apply the second coat at 1 kg per square meter in right angle to the first coat.
• Allow the coating to cure fully for 72 hours to achieve its full properties.
• Once the coating is cured completely, it should be checked for its adhesion to the
substrate. For this mark a square of 5cm x 5cm randomly on the surface.
• Cut the square with a knife diagonally across the square. Rip the coating and check
the thickness with Vernier calipers, to see if the dry film has an average thickness
of 1mm.
• Once these tests are done, reapply BAUCOAT HP over those portions, in
accordance with the regular procedure.
4. Post Application
• Conduct ponding test by filling up to 50mm of water for 48 hours to ensure leak
free terrace.
