Usage Instruction

3 Easy Steps to SUCCEED: Drill, Mix & Fill

1) Drilling *Please call for applications with depths less than 6 inch..

 Drill holes using a hammer drill and appropriate drill bit specific to the

rock or concrete type. (Diagram 1)

 Holes should be drilled no further than 1 ft (30 cm) apart. Note: In

reinforced concrete recommended no more than 8 in (20 cm) apart.

 Recommended hole diameter is 1.5 in (3.8 cm), not to exceed 2 in (5

cm). Drill holes should be 80-90% of the depth, do not go through.

2) Mixing

 In a flat bottom bucket, combine 0.4 gallon (1.5 liter) of water with

one 11 lb. (5 kg.) bag of Dexpan

. (Diagram 2)

 Mix well (a drill and paddle is recommended). If mixing with a stick

or other method, make sure Dexpan

is completely dissolved into the

water. Mix to a slurry.

3) Filling

 Clean holes before filling. Using an air hose to remove excess dust

from drilling.

 Dexpan

slurry should be poured into holes within 10-15 minutes

after mixing. Do not fill to the top, only fill the holes about 1/2 to 1

inch (2.5 cm) from the top.

 Pour well mixed Dexpan

slurry into holes. Agitating the Dexpan

the hole to make sure no air is trapped in holes. Suggestion: Use a

rod or stick to poke holes. (Diagram 3)

 A grout pump might be required to fill horizontal holes. Caps might

be needed for horizontal holes, but only necessary to hold Dexpan

in the holes.

Coverage: Normally one 44 lb. (20 kg.) box of Dexpan

can fill up to

35 lineal feet (10 m) of 1.5 inches (3.8 cm) diameter holes. You might

not have to fill every hole depending on application.

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. Give it 24 hours for best results.

CAUTIONS:

 Read safety and operation instruction CAREFULLY.

 A pair of safety glasses, rubber gloves and a dust mask is required.

Avoid eyes, skin contact. Do not breathe dust.

 DO NOT look directly into filled holes as BLOWOUTS may occur.

 Keep Dexpan

in DRY storage. Seal container after use.

 Select the correct type of Dexpan

for your temperature range.
