Installation
- Step 1 Preparation and Sloping: Check area of application to ensure that it conforms to the substrate requirements as stated in AVM’s System 680 Installation Instructions. If additional sloping is needed, use AVM Crete 6400/6200 as needed to create the necessary slopes. Fill joints, cracks, and flashings with sealant (AVM Aussie Seal M). Recommended; Reinforce sealant with a 6” wide strip of AVM Mat 800 at all moving cracks, flashings, penetrations and other sensitive areas. For cracks over ¼” wide and/ or expansion joints, contact AVM Industries.
- Step 2 Epoxy Primer: Concrete and metal should be primed with AVM 680SC-Epoxy Primer (U-680SC-EP) at a rate of 1 gallon/300 sq.ft. Allow Primer to become tack free before proceeding to Step 3. The base coat must be installed within 8 hours of application of the primer. Otherwise, re-prime.
- Step 3 Membrane Layer: Apply the AVM 680SC Base Coat (U-680SC-BC) at a minimum rate of 67 sq.ft./Gal or as needed to achieve a minimum 24 wet mils. Allow 16 to 36 hours curing time before applying the next coat. (If the base or elastomeric membrane should become dirty or contaminated, or lose their surface tack, wipe clean with xylene, acetone or other safe solvent.)
- Step 4 Aggregate Broadcast Layer: Once the AVM 680SC Base Coat (U-680SC-BC) has cured, apply the AVM 680-SC Aromatic Top Coat (U-680SC-ARTC) by roller, trowel or squeegee in a uniform coat at a minimum rate of 115 sq.ft./Gal (15 wet mils). While the coating is still fluid, uniformly broadcast and thoroughly encapsulate by back-rolling the proper 16 mesh aggregate into the coating at a rate of 12-15 lbs. of aggregate per 100 square feet. Allow 16 to 36 hours curing time before applying the next layer. Use caution! The proper amount of aggregate must be applied and properly encapsulated.
- Step 5 Heavy Duty Traffic Areas (Extra Broadcast Layer where required): In heavy traffic areas, radiuses, and as specified, after the coating in step 4 has cured, apply a 2nd broadcast layer following the same procedures as in step 4.
- Step 6 Top Coat: Apply the AVM 680SC Aromatic Top Coat (U-680SC-ARTC) by roller, spray or squeegee followed by back rolling, in one uniform coat at minimum rate of 105 sq.ft./Gal in order to obtain a minimum coating thickness of 16 wet mils and to completely coat the aggregate.
Optional: For improved color retention, in step 6, Apply AVM 680SC Aliphatic Top Coat (U-680SC-ALTC) in lieu of AVM 680SC Aromatic Top Coat (U-680SC-ARTC)
Quality Control
When applied as directed above, the coating thickness in the Regular Traffic Areas, excluding the encapsulated aggregate, shall be a minimum of 45 dry mils. The coating thickness in the Heavy Duty Traffic Areas, excluding the encapsulated aggregate, shall be a minimum of 55 dry mils. Requires a continuous coating application to minimize lines and/or streaking. Any optional adhesion test is to be performed seven days after product application.
Striping: It is recommended that an Epoxy paint be used for line stripingProtection of Installed Work
The completed section shall be protected from all traffic for the first 24 hours after application and until the surface is sufficiently cured. (The amount of drying time may vary depending on temperature and humidity conditions) Typically, light foot traffic may resume after 4-6 hours.
