Application Method/Spread Rate
ACCELERA EXT is applied in the same manner as standard ACCELERA with a notched or 12” flat window squeegee followed by a cross roll using a 3/8” nap roller. Follow application instructions for all standard ACCELERA systems for complete details. Typical Large kit spread rates:
- Primer: 115 SF/ Kit
- 1st Broadcast Coat: 75 SF/Kit
- 2nd Broadcast Coat: 65 SF/Kit
- Grout Coat: 65 SF/Kit
- Optional Topcoat 200 SF/Kit
NOTE: Above rates calculated using standard Large kit and Dur-A-Flex aggregates.
Cleaning
This product is considered a low maintenance flooring solution, however, certain textures and service environments do require certain procedures.
System Overview
ACCELERA B is a 100%-solids, low-odor, solid color broadcast system consisting of a primer, two pigmented broadcasts of flintshot sand and a pigmented topcoat, all utilizing ACCELERA resin and, hardener. Total nominal system thickness is 1/8 inch.
Surface Preparation
Surface should be profiled, clean, dry, oil free and sound. Shot Blasting is the preferred preparation method. Please refer to the master Surface Preparation Guide for more information. Never feather edge ACCELERA EXT - always terminate in a keyway groove at doorways, drains and exposed edges.
Mixing Area
Select a convenient mix area and protect the surface from spillage by covering with a sheet of plastic and a layer of cardboard. Be generous with the amount of space allocated for this function. The more comfortably your mixer works, the less likely you are to have a “mix error”.
Application Method
Proper planning is essential for satisfactory appearance of the finished floor. Lay out installation in sections to allow full width to be finished in 5 minutes (@70°F/ 50% RH). NOTE: These application instructions are based on using the Large Kit. A smaller kit is available for top-coating coving and smaller areas. NOTE: Normal recoat window is 16 hours (@70°F / 50% RH). If recoating between 16 and 24 hours ACCELERA can be sanded and recoated. Beyond 24 hours use ACCELERA EXT with ACCELERA BP additive. NOTE: Recoat window starts from the time the products are mixed. NOTE: For each application of material and before mixing, mark your batches to ensure you achieve your spread rate targets. This is best accomplished by dividing your target spread rate by the width of the area being coated (or your 95 Goodwin Street East Hartford, CT 06108 Tel: 800-253-3539 • Fax: 860-528-2802 • www.dur-a-flex.com • contact_us@dur-a-flex.com ACCELERA B IMPORTANT! Read these instructions carefully several days prior to starting your work. Seek answers to any questions you may have before you begin. DUR-A-FLEX, Inc. maintains a Technical Staff that will be glad to answer your questions and give you advice pertaining to your particular installation. Use the required PPE for installing Accelera: Carbon Dusk Mask or respirator, safety glasses, long sleeve shirt, long pants, gloves, and work boots. Fresh, moving air is essential to a safe working environment when applying resinous flooring products. IMPORTANT REMINDER: USE PERSONAL PROTECTION EQUIPMENT AND VENTILATION! 4 planned wet edge). Example: If your spread rate is 100 square feet and your area is 20 feet wide you would make a mark every 5 feet (100 divided by 20 = 5). NOTE: Application of ACCELERA where jobsite relative humidity is less than 30% is NOT recommended. Use ACCELERA LH resin for applications where jobsite relative humidity is between 10% and 30%. Spread rates are the same for both ACCELERA, ACCELERA LH, and EXT. NOTE: Cooler temperatures will increase cure time – plan accordingly.
Manpower Requirements
Because of the fast curing of ACCELERA products assign one person to each job – do not multi-task:
- 1 person mixing
- 1 person running pails
- 1 person squeegee
- 1 person cross-rolling
- 1 person broadcasting for every 15 linear feet of wet edge
NOTES: - Additional manpower will be required for complex installations requiring cut-in work. - Above manpower applies to maximum 40 foot wet edge.
Mixer
Mix and apply one batch at a time - do not mix hardener and resin together until batch is ready for immediate application. Pour the hardener into the resin container; scrape bottom and sides with a mix stick to assure that all material is transferred to the resin bucket. Use the hardener pail to scrape the mix stick and never scrape mix stick on the side of the mix pail. Using a ½” 750 RPM drill with a 3 inch jiffler blade, mix the resin and hardener for 30 seconds. Pour the entire batch onto the floor in a 4 to 6” ribbon. Use a notched squeegee on smooth surfaces or a flat squeegee over broadcast surfaces to spread the material evenly. Spread rate will vary depending on substrate, broadcast media and finish texture desired. Cross roll the material pushing a 3/8 inch nap roller in the same direction immediately after the squeegee to ensure there are no puddles. All rolling should be completed within 5 minutes. Allow to cure for 2 hours (@ 70°F / 50% RH).
- Typical Large kit spread rates:
- Primer: 115 SF/ Kit
- Quartz Broadcast Coats: 65 – 75 SF/Kit
- Chip Broadcast Coat: 65 – 75 SF/Kit
- Grout Coat: 65 SF/Kit
- Topcoat: 200 SF/Kit
Note: Small kit = 1/3 Large, Jumbo kit = 2X Large, Application less than 65 SF/Kit may result in bubbles.
Limitations
This product is best suited for application in temperatures between 60°F and 85°F and jobsite relative humidity is between 30% and 65%. Substrate must be clean, sound, and dry. Do not apply over epoxies cured with Fast hardener.
