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: www.epoxy.com/surfaceprep.aspx.
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

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:
Epoxy.com Product #692 � www.epoxy.com/692.aspx. Again be sure to mix small batches.
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).

PRODUCT #77The fresh slurry coat must be broadcast to excess with a wearing coarse of aggregate. Rates will vary from 0.25-1.25#/sq ft depending on type and 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.

Sweep and vacuum all loose sand from the surface (step 4) after the material has hardened. Step 6:Epoxy.com Product #693 � www.epoxy.com/693.aspx. APPLICATIONSURFACE PREPARATONSurface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared as outlined in Epoxy.com Surface Preparation Guide. MIXING/APPLICATIONEpoxy.com Product #693 Methyl Methacrylate (MMA) Sealer and Coating 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 below). At temperatures below 40 ° F, Epoxy.com Product #696 Accelerator 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).
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.
