Flexible Methyl Methacrylate Decking
Installation Quick Overview
Methyl Methacrylate (MMA) Decking Installation Overview
This is a quick guide to the installation of the typical Epoxy.com Flexible Decking Systems and Overlay. This is intended to be a quick
overview. Be sure to consult all of the specific tech data sheet associated with this system as well.
Step 1: Surface Preparation
Prepare the concrete for the installation of the material. Be sure it is
clean and sound:

Step 2: Crack Repair
Repair any cracks � contact Epoxy.com Technical support with details of the
cracking so we can advise you on the best way to do this.
Step 3: Methyl Methacrylate Primer
Product #691 Primer �
www.epoxy.com/691.aspx.
Epoxy.com Product #691 Methyl Methacrylate (MMA) Flooring Primer
requires the addition of Epoxy.com Product #695 Hardener to start the hardening
process. The amount of hardener must be adjusted to the respective surface
temperature (see table below). At temperatures below 40°F, Accelerator 101 must
be used in addition to the amount of hardener used at the 40°F level ( about
� oz by vol./gal. @ 32°F, up to 2.0 oz by vol./gal. @ -20°F

Remember to mix only small amounts that you can use in about 10 minutes.
Spread Epoxy.com Product #691 Methyl Methacrylate (MMA) Flooring Primer evenly
on the surface (no puddles) with notched trowels, and/or squeegees and back
rolled with short nap mohair rollers at no less than 100 sq ft/gal. on very
absorbent surfaces. Two coats may be necessary to get an even, resin-rich
surface to bond with the next layer.
It is recommended to broadcast 16-30 mesh quartz sand Product #77 (approximately
4 lbs/100 sq ft) into the wet primer. This will help in the application of the
coating or troweled mortar. Apply next application only after the primer is
completely hardened.
Step 4:

MIXING AND
INSTALLATION
Epoxy.com Product #692 Flexible Methyl Methacrylate (MMA) is typically used in
conjunction with fillers and fine aggregate and requires the addition of
Epoxy.com Product #695 MMA hardener to start the hardening process. The amount
of hardener must be adjusted to the respective surface temperature (see table).
At temperatures below 40°F, Accelerator 101 must be used in addition to the
amount of hardener used at the 40°F level (about � oz by vol./gal. @ 32°F, up to
2.0 oz by vol./gal. @ -20°F).

Add hardener to the clear resin and blend; add dry powders and mix thoroughly
with propeller mixer. Blend pigment and mix for 1-2 minutes until no lumps are
present. Apply mix to the primed surface using a gauge rake or notched trowel.

size of aggregate. It is recommended to broadcast 16-30 mesh aggregate. Do not
use broadcast aggregate smaller than 30 mesh. Aggregate may be natural or
colored quartz, sand, aluminum oxide, emery, etc.
Epoxy.com Product #692 systems must be top coated, protected, or sealed with
Epoxy.com Product #693 Methyl Methacrylate (MMA) Top Coating. These can be
either pigmented or non-pigmented.

Epoxy.com Product #693 Methyl Methacrylate (MMA) Coating must be applied 50-100
sq. ft./gal. (16-32 mils) for safe through-hardening. To avoid yellowness do not
apply more than 80 mils (20 sq ft/gal.). For outdoor applications add 1%
Epoxy.com Product #693 UV Inhibitor at a rate of 1% by volume. Pigmented
topcoats are achieved by adding pigment packs (1 quart per 5 gallons resin) to
Epoxy.com Product #693 Methyl Methacrylate (MMA) Coating. Apply material with a
notched trowel or squeegee and back roll with a short nap mohair roller.
Broadcast uncured Epoxy.com Product #693 with Epoxy.com Product #77 Broadcast
aggregate at a rate of about 1 lb per square foot.
