Megapoxy MC Heavy Duty Maintenance Coating is recommended for corrosion protection;
floor coating for automotive workshops; kitchens; warehouses; and many other types
of coating applications. Megapoxy MC Heavy Duty Maintenance Coating is ideal for
waterproofing walls and floors; food and beverage production surfaces; decorative
surfaces; and providing abrasion resistance.
Megapoxy MC Heavy Duty Maintenance Coating is a two component heavy duty, 100%
solids, high build, highly chemical resistant and heavy duty maintenance coating
suitable for a variety of commercial and industrial applications. Megapoxy MC Heavy
Duty Maintenance Coating is suitable for floor, wall and steel protection
applications.
Megapoxy MC Heavy Duty Maintenance Coating provides a decorative, hygienic, dust
free coating with heavy abrasion resistance. It is resistant to hydrogen sulphide
that may be present in pipes and plants for the treatment of sewage.
It is recommended that Megapoxy MC Heavy Duty Maintenance Coating is applied in a
three-coat application when used in particularly aggressive and harsh environments.
The three-coat application will give a total cured maintenance coating thickness of
0.4 – 0.5 mm.
Megapoxy MC is volatile organic compounds free (Nil V.O.C.) is suitable for coating
and protecting structures that are in contact with foodstuffs.

How to Use
General
Megapoxy MC Heavy Duty Maintenance Coating is a low-viscosity, heavy-duty
maintenance coating for many types of applications. It is stocked in a range of
colours and is available in conveniently pre-packaged 5kg and 20kg kits with a
simple 3:1 mix ratio by volume (4:1 by weight).
It has a 2-hour work time and a 24-hour cure time at 25ºC.
Surface Preparation
Concrete:
Concrete should be free from grease and oil. If necessary, clean with industrial
heavy duty degreaser. When clean, remove surface laitance. This is best done by
mechanical abrasion such as scabbling, grit blasting or grinding. If this is not
possible acid etching must be carried out. Mix concentrated hydrochloric acid with
equal volume of water and spread at the rate of 0.5 litre per square meter of
concrete surface. Allow to react for about 10 minutes and wash the area thoroughly
and scrub with a stiff bristled broom to remove loose sand. Allow to dry for 24
hours. For maximum adhesion the concrete should be surface dry.
Metal Surfaces:
Metals should be grit blasted to AS CK 9.4 – 1964 Class 3 finish. If this is not
possible, mechanically abrade the surface to a clean, bright metal surface. Once
this abrasion is complete, degrease the surface by flooding with an industrial
grade degreaser. Wire brushing is not entirely satisfactory and gives minimal
adhesion only.
Coated Surfaces:
It is recommend to remove all coatings prior to bonding, bonding to coated surfaces
will give inferior bond strengths compared to bonding directly to a prepared substrate.
• Concrete:
The surface may be either flame-cleaned, or mechanically treated with a scutching
tool, to remove all traces of paint. Complete the preparation by diamond grinding
or scabbling.
• Metals:
Steps should be taken to remove all paint and/or galvanizing. Good quality paint
stripper should be used, followed by grit blasting or grinding to a bright metal
finish.
Safety and PPE
- Megapoxy MC Heavy Duty Maintenance Coating is VOC-free.
- As with all epoxy resins, please wear appropriate PPE, including
eyewear gloves and clothing.
Mixing Procedure
Add the entire contents of Part B into the Part A tin, there is enough space to
combine both parts in the Part A container:
Megapoxy MC 5kg kits & 20kg kits
- Mix the two parts together thoroughly for a minimum of 3 minutes, by
hand or using a mechanical stirrer on a low speed of 200rpm or lower, making sure
to scrape the base and corners of the drum, after 3 minutes, scrape the side of the
drum and mix for a further 2 minutes. - Set a timer do not guess the time.
Megapoxy MC2 5kg kits
- Mix the two parts together thoroughly for a minimum of 2 minutes, by
hand or using a mechanical stirrer on a low speed of 200rpm or lower, making sure
to scrape the base and corners of the drum, after 2 minutes, scrape the side of the
drum and mix for a further 1 minute. - Set a timer do not guess the time.
- It is essential that the correct mixing ratio be used and that the Part
A and Part B are thoroughly mixed together before use. Inaccuracies and poor mixing
will result in lower physical properties of the cured system and, if the error is
sufficiently large, the system may not cure satisfactorily and discolour on ageing.
Application
- Megapoxy MC Heavy Duty Maintenance Coating can be applied by brush,
roller or airless spray equipment. Cut in the edges with a brush before roller
coating. We recommend a three-coat application when used in particularly aggressive
or harsh environments. - Fine aggregates can be broadcast between coats. They can be applied
before curing, as you roll. These can either be left as is for an aggressive non-
slip surface or be re-coated with Megapoxy MC to create a less aggressive non-slip
surface. - For bulk mixing, ensure that all your tools, along with the Part A and
Part B containers, are ready for mixing, but do not combine them or mix multiple
batches at once. Only make your second batch once the first has been applied. - Two thin roller coats will give the best result. Ensure you leave time
for the first coat to set (8 hours) before applying the second coat. - It is recommended that Megapoxy LVS – Low Viscosity Sealer is used as a
primer on particularly porous surfaces before the application of Megapoxy MC.
Megapoxy LVS can be applied either by roller, brush or spray equipment at a rate of
8-10m² per litre. Single coat application of Megapoxy LVS is generally all that is
required and thinning is not recommended. Recoat or overcoat approximately
between 8 – 24 hours after application of Megapoxy LVS. - Megapoxy MC Heavy Duty Maintenance Coating can be thinned up to 10%
with Megapoxy Thinners to promote easy working. Add a maximum of 10% Megapoxy
Thinners on the first coat, 5% on the second coat and so on. However, care must be
taken to ensure that all thinners have evaporated before applying subsequent coats.
If more than 24 hours elapses between coats, it is necessary to thoroughly abrade
the coated surface to a uniform dull finish using 60 grit abrasive paper.
Non-Slip Surfaces
- If you wish to have a non slip surface, broadcast epoxy quality sand,
glass beads, carborundum or silicone oxide over the first freshly applied coat. - This can either be left as is for an aggressive non slip surface, Then
re-coat with Megapoxy MC to lock the aggregate in-between coats. A fine aggregate
can also be mixed through the Megapoxy MC. - Once the Megapoxy MC has been thoroughly mixed, the addition of
approximately 250gms of required aggregate size per 5kgs of Megapoxy MC, should
give a fairly even coat of non-slip when using a roller on the surface to be
coated. - Depending on the grip level required, this can be done in all coats or
just the first one.
Clean-up
- To keep mixing implements and working tools clean, use Megapoxy
Thinners. - Use disposable rubber gloves to protect hands and maintain proper
industrial hygiene. - For further details refer to the Megapoxy MC Safety Data Sheet.
Please Dispose of contents and container in accordance with local, regional,
national and international regulations.
