Part 1 – Information & Preparation
Endüra is high performance decorative resin chip system consisting of 100% solids epoxy resin and colored resin chips. Endüra flooring system is finished with clear catalyst-cured coats of resin available in a satin or gloss finish. The installed system can be textured or smooth as desired. Endüra flooring system, is typically recommended in garage floors, basement floors, workshop floors, laundry room floors, locker room floors, restaurants, food service areas, hospitals and fire stations.
Surface Preparation is the most critical portion of any successful resinous flooring system application. All substrates must be properly prepared as outlined in Technical-Bulletin-1.pdf. Specific attention should be paid to the following:
- Concrete Placement - An efficient vapor barrier should be directly under slabs on or below grade to prevent moisture migration
- Curing and Finishing techniques of the concrete substrate
- Age of concrete
- Previous contamination of the substrate
- Present condition of the substrate
- Make sure the floor is free of moisture vapor transmission
Also, the temperature conditions of the area to receive the flooring system should be checked. An optimum room temperature of 75°F with a slab temperature of 50°F is required for proper cure of the resin flooring system.
|GUIDELINE SYSTEM REQUIREMENTS FOR 1000FT2|
|Endüra E02a||100% solids epoxy primer||4.0 gal|
|Endüra E21||100% solids epoxy body coat||6.0 gal|
|Resin Chips||For full broadcast||55-70 lbs|
|Endüra P70b||100% solids polyaspartic clear coat||4.0 gal|
|Additive||Non-skid additive, fine or coarse||Varies|
The application of primer Endüra E02 is optional
Instead of Endüra P70, One coat of Endüra E12 and one coat of Endüra U50 can be used
While priming is optional on broadcast systems, Düraamen recommends that every flooring system be installed with a primer to insure maximum adhesion to the prepared substrate. Priming will also help to sea air in the concrete and prevent outgassing and air bubbling in the finished system.
1. mixing endüra e02*, low modulus epoxy primer
- Stir each component prior to mixing.
- Mix 2 parts by volume of Part A (base) with 1 part by volume of Part B (hardener) for three minutes with a low speed electric drill mixing paddle.
- If thinning is desired, add no more than one pint of Xylene per gallon of epoxy at the time of mixing.
- Mix only that amount of material that can be used in 20-25minutes. Do not let mixed material sit in the mixing container longer than 5 minutes or working time will be significantly reduced.
* If the moisture vapor emission rate or moisture content exceeds the stipulated maximums, use Perdüre MVT in lieu of Perdüre E02.
- Pour primer onto the prepared concrete substrate.
- Spread with either a flat trowel or squeegee to a coverage of 25°-275 ft² per gallon.
- Backroll with a short nap roller.
Allow the Primer to cure for 12-16 hours.
Part 3—Application of Body Coat and Chip Broadcast
1. mixing endüra e21, 100% solids epoxy body coat
- Thoroughly mix each component prior to combining.
- Mix 4 parts by volume of Part A (resin) with 1 part by volume of Part B (hardener) for three minutes with a low speed electric drill mixing paddle.
- Do not mix more material than can be used in 20-30 minutes.
- Pour material onto floor in a line and spread with a flat or notched squeegee to a coverage of 160 ft²/gal. This will yield 10mils dry film thickness.
- Backroll with a short nap roller to even the surface texture of the coating.
- To minimize marks in finished system, the contractor should wear ‘spiked’ shoes while walking on wet material.
- Allow the material to level before broadcasting chips.
Termination points at the end of the day should be made at doorways, expansion joints, etc. If it is not possible to terminate at these points, 2" masking tape should be placed in a straight line at the ending point. Carefully trowel the material up to and slightly over the inside edge of the tape. Allow material to cure for about thirty (30) minutes and remove the ape.
3. broadcast to excess
Broadcast blended resin chips into the wet body coat until the surface is completely covered. Be careful not to clump the material or produce high-spots. Approximately 55-70 lbs of chips will be needed for 1000 ft² of flooring, depending on thickness of resin and broadcast technique. A one gallon container holds approximately 8 lbs of chips. If terminating the system with tape as described in note above, broadcast chips up to the tape and remove after material cures for 30 minutes.
Remember to only walk on the wet surface while wearing ‘spiked’ shoes!!! Do not rotate your feet while walking with spike shoes to avoid creating gouges in the floor.
For projects requiring a very light broadcast of chips, broadcast lightly into the wet body coat. This is typically a random broadcast using approximately 10-15 lbs. of broadcast of chips for 1000 ft². If terminating the system with tape as described in the note above, broadcast chips up to the tape and remove after material cures for 30 minutes.Remember to only walk on the wet surface wearing ‘spike’ shoes.
4. allow the broadcast floor to cure overnight.
Sweep excess chips with a stiff bristled broom and/or vacuum.
Part 4—Application of Grout Coat / Top Coat
The applicator should complete the broadcast portion of the application prior to grouting. Thoroughly and lightly sand dry resin chips with pole sanders (36 grit sand paper) in two directions prior to grouting with Endüra P70 (or Endüra E10 and Endüra U50). A floor buffer with abrasive screen (60-80 grit) mounted to the white pad can also be used. Be very careful with this technique…keep the buffer moving at all times, left motion, pulling rather than pushing. Broom and vacuum the loose particles from the floor surface.
1. mixing endüra p70—100% solids polyaspartic polyurea coating
- Stir each component prior to combining.
- Mix 2 parts by volume of Endüra P70 Part A (base) with 1 part by volume of Endüra P70 Part B (hardener) for three minutes with a low speed electric drill mixing paddle.
- Mix only that amount that can be used in 15-20 minutes.
- Immediately pour mixed material onto the floor in strips and spread at a rate of 200-250 ft² per gallon using a trowel or squeegee. To achieve smoother surfaces, apply at a spread rate of 160 ft² per gallon. It is recommended that the material be lightly back rolled with a short or medium-nap roller to smooth and level any tails or ridges.
- To minimize marks in the finished system, the contractor should wear ‘spiked’ shoes while walking on wet material.
- Allow the material to level.
- For full broadcast, it may be necessary to apply two coats of Endüra P70, especially if Endüra P70 is thinned with MEK to extend its pot life. Allow 8-10 hours between multiple coats of Endüra P70. In colder and humid climates, allow 14-16 hours between the coats.
Termination points at the end of the day should be made at doorways, expansion joints, etc. If it is not possible to terminate at these points, 2" masking tape should be placed in a straight line at the ending point. Carefully trowel the material up to and slightly over the inside edge of the tape. Allow material to cure for about 30 minutes and remove the tape.
The floor can be opened for light traffic after 6-8 hours at 75°F.
