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

• Ready to use / apply single component

product

• Forms a highly elastomeric, tough and

resilient membrane.

• Environment friendly

• Fast surface hardness, no tack surface, low

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.

• Good chemical resistance against diluted

acids, oil, salts, bacteria and common fuels.

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.
