Self-Leveling and DP600NS

8

Note: Not for use in repairing or anchoring diving boards.

Preparation of Hand/Grab rails

1. Bore a hole through the base of the hand/grab rail just above grade level to

allow introduction of the product.

2. Using 80 grit sandpaper, roughen the footing surface of the hand/grab rail

which is to be imbedded below the concrete grade.

3. Refer to instructions on cartridge for dispensing.

Preparation of Concrete for Re-anchoring

1. Chip away the cracked or broken concrete to allow removal of the hand/grab

rail.

2. Leave the concrete as close as possible around the hand/grab rail. It is best to

allow the concrete to remain intact as close as possible (within 1/2 to 1 inch all

around) to the base of the hand/grab rail.

3. Dig down to the base of the concrete, typically 4- to 6-inches deep.

4. Expose any rebar, if possible, in order to create a ground connection to the rebar.

5. Create as much as a 1-inch undercut under the concrete in a smooth taper from

the concrete surface.

6. Remove all of the loose concrete particles and dust prior to encasing

the replacement hand/grab rail.

7. Attach the replacement hand/grab rail to surrounding rebar using a copper wire.

Cinch the connection down tightly, allowing a slight amount of slack in the

wire connection.

8. Create a shield to corrosion at the base of the hand/grab rail by laying a

piece of polyethylene plastic at the base of the hole.

9. Insert the hand/grab rail in the hole. Align the hand/grab rail for its elevation

and vertical plumb.

Encasement Procedure

1. Dispense 3M™ Scotch-Weld™ Urethane Adhesive DP600 Self-Leveling or

DP600NS into the concrete hole. Product will remain liquid for approximately

50 seconds, and fully cure in 1 hour. Dispense more cartridges as necessary to

bring the fill level up to the concrete surface level.

2. Dispense 3M™ Scotch-Weld™ Urethane Adhesive DP600 Self-Leveling or

DP600NS into the inside of the hand/grab rail. Fill with product up to and

slightly above the grade level. (Filling the inside of the post provides extra

strength and protection against corrosion.)

3. Apply cement dust or sand, if desired, to blend the surface appearance into

the surrounding concrete.

4. If 3M™ Scotch-Weld™ Urethane Adhesive DP600 Self-Leveling or DP600NS

is applied in a traffic area, apply sand or some type of grit to repaired surface

area.

Repair Clean-up and Finishing
