Coverage is based on a filling a 1/4" wide by 1/2" deep crack or joint. ElastiPoxy can be used with or without sand depending on the type of void you are filling.
FLEXIBLE REPAIR (straight, without sand): 2-quarts will fill approximately 75 ft. (2-gallons fills approximately 300 ft.)
RIGID REPAIR (4:1 sand-to-ElastiPoxy ratio): 2-quarts will fill approximately 375 ft.
Before using ElastiPoxy the concrete or masonry surfaces must be clean. Remove ground-in dirt, paint, oils, grease, efflorescence, or bond-inhibiting contaminants. Air blow or shop-vac any loose debris or dust.
The surface may be slightly damp but a dry surface is preferred for best results. Surface temperature must be above 40 °F during the application and for 24 hours afterwards (see curing times below).
* Make sure that ElastiPoxy does not bond to the bottom of the control joint or crack. Using the backer rod and/or sand will prevent this from happing. Example; If the filler adheres to the bottom of the joint and the crack in the bottom is 1/8" wide, a 1/8" movement of the concrete would require a 100% elongation of the epoxy spanning the crack. This exceeds the limits of elastic epoxies and the joint filler would crack.
Exact measurement is important and must be adhered to! ElastiPoxy has a short pot life – 30 to 45 minutes. Mix only as much product as you can easily apply within 30 minutes.
STEP 1 – Using the two drill mixing attachements provided, mix each container (A & B) with your slow-speed electric drill. Do not cross contaminate the mixers.
STEP 2 – Using the measuring cups, pour equal amounts of Compounds A and B into seperate mixing cups.
STEP 3 – Mix both compounds together by pouring them into a clean mixing cup, plastic pail, or similar.
STEP 4 – Mix both compounds together for at least 2 minutes using one of the mixer attachements.
ADD SAND IF NEEDED - Add construction sand (or sand without fines) - at the appropriate ratio - to the mixture using a measuring cup. Mix thoroughly for 3-5 minutes. Using sand provides a stiffer mixture for vertical surfaces, more volume, and a rigid rather than flexible repair.
STEP 5 – After mixing, allow the mixed ElastiPoxy to off-gas for 15 minutes.
STEP 6 – Tack-coat the joint, crack, or surface with pure epoxy (without sand) using a paint brush.
POT LIFE – 30-45 minutes. CURING TIME – Depends greatly on ambient temperature:
|80°F or higher||45 minutes – 1.5 hours|
|65°F to 79°F||1 hour – 3 hours|
|50°F to 64°F||3 hours – 4 hours|
|49°F and below||4 hours – 8 hours|
Tools clean up with water while still wet after installation (if cured, clean using xylene or aromatic solvent.)
Unopened containers – 1 year. Store in a cool dry location out of direct sunlight. AVOID FREEZING!
