PROCEDURE
1. Surface Preparation
a) Concrete shall be a minimum of 21 days old and/or the
residual moisture content shall be below 6%. Ensure that
the concrete is clean and free from dust, laitance,
grease, oil, curing compound, existing paint finishes,
etc.
Blow holes and defective concrete shall be made good
using a proprietary repair compound e.g. Floorpatch MMA.
Suitable mechanical treatment, such as vacuum grit
blasting, is the preferred treatment prior to
application, as this ensures a mechanical 'key' which
will optimise adhesion.
b) Steel surfaces shall be shot blasted or grit blasted
to a nominal Sa 2.5 Swedish Standard.
All dust shall be removed prior to coating application.
A coat of Tackprimer MMA shall be applied as soon as
practicable after blasting, in order to obviate the
possible occurrence of 'flash rusting'.
2. Priming
a) Concrete surfaces shall be primed with a coat of
Tackprimer MMA, applied by brush, roller, or airless
spray, at the nominal rate of 0.3Kg/Sq.m.
Long nap lambswool rollers are recommended for primer
application. Allow primer to cure fo ra minimum of 30
minutes.
b) Steel surfaces shall be primed with Tackprimer MMA (see
section 1b above).
3. Mixing
Deckcoat MMA is supplied as a four pack material
consisting of: the RESIN component, the CATALYST
component, the FILLER component, and a PIGMENT component.
Add the CATALYST component to the RESIN component and mix
thoroughly, preferably by mechanical means, for a minimum
of 2 minutes. Pour the contents into a mixing vessel, and
add the FILLER and PIGMENT component whilst stirring. A
low speed drill with paddle attachment may be used, or
else a forced action mixer e.g. Creteangle type.
4. Application
Pour the mixed material onto the prepared and pre-primed
surface, and apply by serrated trowel to the desired
thickness.
De-aerate the material by spike rollering.
Within 5 minutes, broadcast the appropriate aggregate at
a nominal rate of 8Kg/Sq.m. When cured, sweep off excess
aggregate.
5.Sealing
The application of a clear sealer coat is recommended to
reduce tendency towards staining and dirt pick up, and
thereby ensure optimum ease of cleaning.
Apply a roller coat of MMA Clear Sealer, flexible grade,
at a nominal rate of 0.3 Kg/Sq.m. and allow to cure for a
minimum of 2 hours prior to putting back into service.
6. Equipment Cleaning
Clean all equipment, immediately after use, with
TOOLCLEAN.
7. Curing
Allow a minimum cure time of 1 hour @ 20C prior to
overcoating or foot trafficking. For optimum chemical
resistance, a minimum cure time of 24 hours @ 20C should
be allowed.
8. Packing
Deckcoat MMA is supplied in 20Kg packs.
9. Coverage
A 20 Kg pack is sufficient to cover an area of 2.8 Sq.m.
at a thickness of 4mm.
10. Storage and Shelf Life
Store in dry, cool conditions, preferably at temperatures
between 10C and 20C, and out of direct sunligbt.
Adequate ventilation of the storage area should be
provided.
Keep containers tigbtly closed when not in use.
Deckcoat MMA has a minimum shelf life of 6 months when
stored in original, unopened containers, in accordance
with manufacturer' s instruction.
11. Limitations
Do not apply to wet or uncured concrete.
Deckcoat MMA will taint food during application, so that
all foodstuffs in the immediate vicinity must be removed
or properly covered.
12. Health and Safety
Deckcoat MMA is flammable during application, so that
adequate safety precautions should be observed.
Please refer to the separate Material Safety Data Sheet
and General Information Sheet before use.
