the proven performer has evolved since 1951 into the most versatile bonding
and sealing agent available.
-
Bondcrete
contains an exclusive resin additive ensuring maximum bonding strength.
-
Bondcrete
is so strong there is seldom any need to hack, chip or acid etch the surface
before bonding.
-
Bondcrete
is a concentrated high solid product, which in most cases provides a high
dilution ratio, ensuring the customer gets value for money.
PREPARATION
Before
applying Bondcrete ensure that surface is free of dirt, dust, oil, grease
and loose or flaking materials.
Do
not use Bondcrete in permanently wet or damp areas unless it is mixed and

and other Bondall waterproofing products. Do not use Bondcrete Bondcrete
in temperatures below 10°C. Bondcrete is not recommended for bonding
of plastic and rubber.
APPLICATION
-
CARPENTRY,
JOINERY & GENERAL CRAFT WORK:
Apply
direct from container to one surface only. Press surfaces together and
lightly clamp. Bondcrete sets in approx. 30 minutes. Max strength is attained
in 12 hours
-
PRIMING
AND SEALING PRIOR TO PAINTING:
One
sealing coat of diluted Bondcrete (Bondcrete1: water 4) will provide an
excellent sealer or key when applied to new or old cement rendered walls,
plaster etc. before using water borne decorative paints (see paint manufactures
instructions). Allow 24 hours to dry. Do not attempt to apply oil-based
paints over Bondcrete.
-
DUST
PROOFING AND/OR RETARDING OIL PENETRATING OF INTERIOR CONCRETE FLOORS:
To
a clean floor apply a sealing coat of diluted Bondcrete (Bondcrete 1: water
6) by brush, roller or spray. Leave to dry for 12 hrs. Approx. Apply another
sealing coat with a dilution of Bondcrete (Bondcrete 1: water 4), allow
to dry. Please Note: do not seal floor
with
Bondcrete if you intend to use an oil-based paving paint or similar floor
coating system. For exterior use, apply Bondall Clear Paving Sealer.
-
TOPPINGS
RENDER OR PATCHING:
Apply
sealer coat of Bondcrete (Bondcrete 1: water 4) allow to dry. Apply bondcoat
of Bondcrete (Bondcrete 4: water 1) and while still wet or tacky carry
out topping or patching. Use Bondcrete admixture (Bondcrete 1: water 10)
in the topping/patching mixture in place of normal water.
-
PLASTERING
SETTINGS ONTO CONCRETE CEILINGS, WALLS ETC:
Apply
one sealing coat of diluted Bondcrete (Bondcrete 1: water 4) allow to dry.
Apply one bondcoat of diluted Bondcrete (Bondcrete 1: water 1) to the surface
and while this coat is still tacky, plaster with hardwall plaster mixed
to required consistency with Bondcrete admix (Bondcrete 1: water 4) in
place of normal water. Screed bedding to required level and bed the tiles
immediately.
-
TILING:
Apply
sealer coat of diluted Bondcrete (Bondcrete 1: water 4) to surface and
allow to dry. Apply bondcoat of diluted Bondcrete (Bondcrete 1: water 1)
to sealed surface and while still wet or tacky lay bedding.
Beddings
up to 6mm – 1 part cement: 2 part fine sand
Beddings
over 6mm - 1 part cement: 3 part fine sand
Mixed
to a workable consistency with Bondcrete admix (Bondcrete 1:water 4) in
place of normal water. Screed bedding to required level and bed the tiles
immediately. As Bondcrete has a multitude of other uses, the above are
some of the more common uses for Bondcrete.
THINNING
Bondcrete
may be diluted with water when doing the following:
A
sealing coat: (Bondcrete 1: water 4)
A
bondcoat: (Bondcrete 1: water 1)
Bondcrete
as an admixture to sand and cement: (Bondcrete 1: water 10)
There
are other Bondcrete/water dilution ratio but it is advised to follow as
specified.
DRYING
Drying
times vary pending on how it is being used and temperatures.
If
applied neat: Bondcrete sets in 30 minutes but attains max strength in
24 hours.
As
a thumb rule allow application to dry for at least 24 hours before applying
second coat.
COVERAGE
Estimates
below will provide a useful guide:
Bondcrete
undiluted = 3.5 square metres per litre
Bondcrete
diluted:
Bondcrete
4 parts: water 1 part = 8 square metres per litre
Bondcrete
1 part: water 1 part = 17.5 square metres per litre
Bondcrete
1 part: water 4 parts = 35 square metres per litre
Bondcrete
as an admix: Bondcrete 1 part water 10 parts is an ideal admix ratio for
cement toppings, concrete, plasters etc. For estimating purposes 2 litres
of Bondcrete diluted with 20 litres of water is normally sufficient for
mixing each 40 kg bag of cement.
COLOUR
