APPLICATION
MasterFlow 810 can be mixed to a flowable or
trowelable consistency. The quantity of water
required for a 25 kg bag is approximately as shown
below:
Flowable: 4.5 litres
Trowelable: 3.2 – 3.4 litres
Water addition may be affected by temperature
conditions on site. Trials are recommended to
determine the correct water requirement.
MasterFlow 810 should be mixed using a suitable
mixer. For flowable consistency, use a hand drill
and paddle for small works up to two bags at a
time and specialise grout mixers for larger volume.
Drum type mixers may not provide sufficient mixing
efficiency to derive the optimum performance from
the grout.
The correct volume of water should be added to
the mixer followed by the powder. Mixing should
continue until the grout has a smooth, lump free
appearance. This will normally be between 3 – 5
minutes after mixing has started.
For best results, MasterFlow 810 should be used
within 30 minutes once mixed.
The substrate should be properly prepared and
should be free from contamination, laitance and
loose material. Thoroughly saturate the substance
with water at least 2 – 3 hours prior to pouring the
grout. All free water ponding should be blown out
of the void just before pouring the grout.
As for all cementitious materials, curing is essential
to prevent rapid drying out of the grout and

APPLICATION
Surface Preparation
Correct substrate preparation is critical for optimum
performance.
Surfaces should be structurally sound, clean, and free
from loose particles, oil, grease, or any other
contaminant. Cement laitence, loose particles, mould
release agent, curing membrane, and other
contaminants must be removed by wet grit blasting, high
pressure water jetting ( approx. 150 bars) or such other
effective methods.
Fill surface irregularities such as blow holes,
honeycombs etc., with EMACO repair mortar to achieve
a smooth and level surface.
Saturate the prepared substrate with clean water before
applying MASTERSEAL 555S.
Mixing
Mechanical mixing is necessary. A slow speed ( 600
rpm) , heavy duty electric drill with a wing type paddle is
recommended. Place half to two thirds of Part A ( white
liquid) in the clean container supplied. Keeping the mixer
running, add Part B ( powder component) slowly and
steadily. Add the remaining liquid and mix for at least 2
minutes until a homogeneous lump free consistency is
obtained.
Placing
It is extremely important that the area being treated is
shaded from direct sun rays and wind to prevent rapid
drying of the coating.
Apply MASTERSEAL 555S evenly using a roller block
brush. or by a notched trowel, onto the prepared surface,
to give a continuous film. In case of large areas
MASTERSEAL 555S can be spray applied using a
worm-gear type of spray equipment.
Apply at least two coats perpendicular to each other with
an average wet film thickness of 0.75 mm each. To avoid
pin holes, apply the second coat at right angles to the
direction of first. Ensure that no air is entrapped in the
membrane during application.
If during the application the mix stiffens, discard it and
prepare a fresh mix for application.
Do not apply on external surfaces if rain is anticipated
within 2 hrs.
MASTERSEAL® 555S
Curing
Slow drying of MASTERSEAL 555S membrane ensures
homogenous curing and high waterproofing
characteristics, however, MASTERSEAL 555S must be
protected against rapid drying due to high temperatures
or wind. No further curing treatment is required.
Any subsequent, compatible paint finish may be applied
after 7 days.
EQUIPMENT
Mixing : A heavy duty slow speed ( approx. 600 rpm) drill
fitted with a wing type mixing paddle.
Placing: Worm-gear type spraying machine, roller or
block brush.
Note : Worm - gear type of sprayers do not normally
have a mixing arrangement. Therefore, material has to
be mixed separately and fed to the spraying machine.
CLEANING
Clean tools and equipment with water, before the coating
hardens.
ESTIMATING DATA
The minimum recommended coverage of
MASTERSEAL 555S is 0.9 – 1.0 kg/ m2 per coat to get
approx. 0.65 – 0.75 mm thick wet film build. Therefore,
for two coats, the material requirement is 1.8 – 2.0 kg/ m2.
Actual coverage depends upon the method of
application, the texture and porosity of the surface.
PACKAGING
MASTERSEAL 555S is supplied in the following packs:
Pack size Part A Part B
45 kg 20 kg 25 kg
SHELF LIFE
MASTERSEAL 555S can be kept for 12 months from

that will typically set in 3 - 5 minutes when mixed with
clean, potable water. Actual setting time depends on
the temperatures of the powder, mixing water, ambient
air and substrate. MasterSeal 590 expands as it sets
to lock into place even under constant water pressure.
MasterSeal 590 repairs have exceptional strength
and durability and will seal out water for the life of the
structure. MasterSeal 590, containing no metallic
aggregate or corrosive agents, will not shrink or
oxidise, and is suitable for water immersion service
when cured.
It is certified by National Sanitation Foundation ( NSF)
to conform to the requirements of NSF Standard 61 for
Drinking Water System Components.
RECOMMENDED USES
MasterSeal 590 is designed to be used:
• To stop active water or seepage under pressure
through joint, static cracks and holes in concrete or
masonry, where a normal mortar would be washed
away and resin would not bond.
• As a seal for construction joints or floor joints prior
to basement tanking with MasterSeal 581.
• For scaling cracks and construction joints in
reservoirs and other water retaining structures.
• For instant sewer connections.
• For rapid anchoring of bolts, conduits, pipes,
railings, sanitary equipment, etc.
• For joint filling and pointing between concrete
segments in concrete and brick tunnels, sewage
systems, pipes and mines.
FEATURES AND BENEFITS
• Chloride-free - Will not promote corrosion of
reinforcement.
• Expands as it sets - Ensures a permanent
watertight seal.
• Mechanical characteristic similar to
concrete – expands and contracts with thermal
movements
• Cost effective – only use what is necessary for
job.
• Ultra-rapid setting - Instant leak plugging.
• Easy to apply – Mix with water

APPLICATION
Surface preparation
Ensure that the area around the hole to be plugged is
free of scale, contaminants or loose materials
Mixing
MasterSeal 590 powder should be mixed with
clean water by hand only. Mix quickly and well to
a stiff consistency using approximately 0.26 litres
water for 1 kg of powder. Do not mix more than
can be place within one application, 1-2 minutes
( at 20° C) . Do not re-temper.
Placing
Place MasterSeal 590 with minimum working,
kneading, or rubbing. Force MasterSeal 590 repair
mortar into cracks or holes and hold it in place ( without
twisting) , until set is fully achieved. Just prior to final
hard set, it may be " shaved" with a trowel until flush to
the surrounding surface. Always shave from the centre
out. If the is in a dry condition at the time of placement;
keep damp for 15 minutes minimum, using a fine
spray misting of water, before and after placement.
Sealing Junction
To seal static cracks at the junction of the floors and
walls, cut out the crack at least 19mm wide and
deep, and slightly undercutting, if possible. Flush
away all loose debris, dust, and dirt with clean water.
Force MasterSeal 590 in the prepared crack with a
round tool and smooth out to form a cove at wall-tofloor
junctions. Keep damp for at least 15 minutes.
