1. Drilling Holes should be drilled no further than 1 ft (30 cm) apart. Recommended hole diameter is 1.5 in (3.8 cm). Drill holes should be 80-90% of the depth, do not go through.

2. Mixing In a bucket, combine 0.4 gallons (1.5 liters) of water with one 11 lbs (5 kilograms) bag of DEXPAN. Mix well, using a drill and paddle is recommended.

3. Filling Clean holes before filling. DEXPAN slurry should be poured into holes within 10-15 minutes after mixing, only fill the holes about 1/2 to 1 inch (2.5 cm) from the top. Agitating the DEXPAN in the hole to make sure no air is trapped in holes. A grouting pump might be required to fill horizontal holes. Caps might be needed for horizontal holes.

4. Coverage: Normally one 44 lb (20 kg) box of DEXPAN can fill up to 35 lineal feet (10 meters) of 1.5 inches (3.8 cm) diameter holes. Might not have to fill up every hole depending on application.

5. Cracking Or Cutting Time Properly mixed, the cracks may appear after 2 hours of filling drilled holes, depending on ambient temperature, humidity, rock or concrete hardness.

6. Cautions: A pair of safety glasses, rubber gloves and a dust-proof mask is required. After filling DO NOT look directly into the holes as to avoid any accident to be caused by blow-out. Keep DEXPAN in DRY storage.
