Application
Polyurethane foam.
Applicators must recognize and anticipate climatic conditions prior to application
to ensure highest quality foam and to maximize yield. Ambient air and substrate
temperatures, moisture and wind velocity are all critical determinants of foam
quality. Extreme ambient air and substrate temperature will influence the
chemical reaction of the two components, directly affecting the yield, adhesion
and the resultant physical properties of the foam insulation. To obtain optimum
results, polyurethane foam should be spray-applied to substrates when ambient
air and surface temperatures are between 10ºC and 50°Cº. All substrates to be
sprayed must be free of dirt, soil, grease, oil and moisture prior to the application
of polyurethane foam. Moisture in any form: excessive humidity (>85%R.H.) rain,
fog, or ice will react chemically and will adversely affect system performance and
corresponding physical properties.
Application should not take place when the ambient temperature is within 3°C of
the dew point. Wind velocities in excess of 20 km per hour may result in excessive
loss of exotherm and interfere with the mixing efficiency of the spray gun
affecting foam surface texture, cure, physical properties and will cause overspray.
Precautions must be taken to prevent damage to adjacent areas from fugitive
overspray.
Applicators should ensure the safety of the jobsite and construction personnel by
posting appropriate signs warning that all "hot work" such as welding, soldering,
and cutting with torches should take place no less than 35 feet from any exposed
foam. If "hot work" must be performed all spray polyurethane foam should be
covered with an appropriate fire or welder's blanket, and a fire watch should be
provided.
Rubberized Bitumen Emulsion
All surfaces must be clean and dry and free from dirt, dust, oil and grease. All
loosely adhering particles such as rust, scale, and cement laitance should be
removed. All organic growth should be removed using a fungicidal wash, followed
by thorough washing with clean water.
Rubberized bitumen emulsion should be applied by brush or squeegee to
prepared surfaces. Stir well before use, replace lid when not in use. Soak up any
spillage with sand or sawdust and wash down surface immediately.
Apply at the rate of 1m² per litre, to give a minimum dry film thickness of 350
microns, as per CP102:1973.
Allow a minimum of 24 hours drying period before applying a water test.
Water Test
Make a water test for 48 hours
Separation Layer
Install a separation layer of Geotextile 120g/m2 over the polyurethane foam.
Screed in Panels
Then start making slope panels for screed.
Then apply the screed in panels at an average thickness of 7 cm, and highest
thickness of 10cm.
Cementious Finishing Coat
Apply a cementitious coat to protect atmospherically exposed reinforced
concrete structures from attack by acid gases, chloride ions, oxygen and water.
Mix the cementious product and water in slurry like consistency and apply while it
is still wet.
For best results, surfaces should be damp. In order to obtain the protective
properties of the cementious, it is important that the correct rates of application
are observed.
Use a short stiff brush (preferably 120 - 200mm width) and apply in one or two
coats as required.

air and substrate temperatures, moisture and wind velocity are all critical
determinants of foam quality. Extreme ambient air and substrate temperature
will influence the chemical reaction of the two components, directly affecting
the yield, adhesion and the resultant physical properties of the foam

to substrates when ambient air and surface temperatures are between 10ºC
and 50°Cº. All substrates to be sprayed must be free of dirt, soil, grease,
oil and moisture prior to the application of Baymer Spray. Moisture in any
form: excessive humidity (>85%R.H.) rain, fog, or ice will react chemically will
adversely affect system performance and corresponding physical properties.
Application should not take place when the ambient temperature is within 3°C
of the dew point. Wind velocities in excess of 20 km per hour may result in
excessive loss of exotherm and interfere with the mixing efficiency of the spray
gun affecting foam surface texture, cure, physical properties and will cause
overspray. Precautions must be taken to prevent damage to adjacent areas
from fugitive overspray.
Applicators should ensure the safety of the jobsite and construction personnel
by posting appropriate signs warning that all "hot work" such as welding,
soldering, and cutting with torches should take place no less than 35 feet from
any exposed foam. If "hot work" must be performed all spray polyurethane
foam should be covered with an appropriate fire or welder's blanket, and a fire
watch should be provided.
Processing Equipment:
2:1 transfer pumps are recommended for material transfer from container
to the proportioner. The plural component proportioner must be capable of
supplying each component within ± 2% of the desired 1:1 mixing ratio by
volume. Hose heaters should be set to deliver 50°C to 55°C materials to the
spray gun. These settings will ensure thorough mixing in the spray gun mix
chamber in typical applications. Optimum hose pressure and temperature will
vary with equipment type and condition, ambient and substrate conditions, and
the specific application. Some equipment may require you to heat drums to
achieve optimum material temperature. It is the responsibility of the applicator
to properly interpret equipment technical literature, particularly information that
relates acceptable combinations of gun chamber size, proportioner output,
and material pressures. The relationship between proper chamber size and
the capacity of the proportioner ’s pre-heater is critical. Contact your machine
supplier representative for specific recommendations, pricing, and availability
of spray and auxiliary equipment.

BLD PU SEALANT
DESCRIPTION
is a novel low modulus expansion joint sealant, especially
formulated to ensure bubble free cure even at very high
temperature and humidity climatic conditions. The product
displays excellent thixotropy allowing its use even in very
large expansion joints. It cures by reaction with atmospheric
humidity to produce a joint sealant with a %50 joint movement
accommodation factor and excellent adhesion on substrates
traditionally problematic for PU sealants, e.g. glass, aluminum,
steel, polycarbonate, etc. The extrusion rate and tooling of the
sealant remain the same throughout a very wide range of
temperature and humidity conditions.
LIMITATIONS
Not recommended for direct application on unsound substrates. In this case,
the substrate must be primed with PRIMER, which will re-enforce the concrete
and produce a strong durable substrate for sealant application.
Highly porous substrates, dusty surfaces or poorly compacted concrete,
must have their porous bond area surfaces thoroughly sealed to avoid the
possibility of air bubbles being blown into the uncured sealant if the substrate
temperature rises.
RECOMMENDED FOR
Sealing joints in:
Insitu concrete
Metal frames
Expansion concrete plates
Aluminum windows and panels
Preacast panels
Irrigation channels
Brick and block work
Glass
Water tanks and swimming pools
Granite and marble
FEATURES AND BENEFITS
No bubbling/swelling upon curing in difficult climatic conditions.
Excellent Thixotropy.
Excellent adhesion on almost any type of surface, with or without the use of
special primers.
Excellent extrusion, tooling and storage stability over wide range of climatic
conditions.
Excellent chemical resistance, suitable for sealing joints in swimming pools
and chemically treated water.
Low modulus, joint movement accomodation %50.
Microorganism and fungus resistant.
Excellent heat resistance, suitable for application where exposure to
temperatures >°60C take place.
Resistance to cold: The sealant remains elastic even down to °40-C.

APPLICATION
SURFACE PREPARATION:
Substrate should be sound, clean and free from dirt, dust, laitance and all
loosely adhering particles. Absorbent cement based surfaces should be
thoroughly saturated with water to achieve surface saturated dry
condition. All cracks larger than 1mm should be filled with cement base
concrete repair.
APPLICATION:
Apply two coats BLD PROOF PU at 1.0mm per coat thickness directly to
the prepared substrate after mixing the BLD PROOF PU with slow feed
mixer, then apply it using notched trowel and spread the product evenly
over the area. Apply two coats in order to avoid pinholes.
