Harbor Freight Tools 94849 operating instructions Fillers

Fillers:

Fillers are designed to fill large gaps and provide a flexible and waterproof joint between large surfaces. Typical uses include around chimneys, masonry joints and sections of concrete. Fillers are often sold in larger sized cartridges. To reduce cost, joints are often partially filled with “caulk rod” or sand before being topped with filler.

How to apply caulk, adhesive or fillers:

1.Select the proper caulk, adhesive or filler for your application. Have the correct clean up materials ready, including scrapers, rags and solvent.

2.Prepare your work materials before applying caulk. Your project should have been test fitted or assembled. Have clamps or any other needed tools available. Caulk, adhesive or fillers are a final step in construction. They are not designed to be removed once applied.

3.If using caulk in a seam, apply painter’s tape along both sides of all seams before applying the caulk. Leave a very small space, usually less than 1/8” between the edge of the painter’s tape and the seam. This is the amount of caulk that will be vis- ible on completion of the job.

If using caulk, next apply a small bead of caulk along the seam for no more than a few feet. Using a spreader, rub along the seam to smooth the caulk into the seam. Excess caulk will be on the tape. Using the spreader, rub excess caulk from the tape into the seam. Continue until all seams have been filled.

Before the caulk has dried, remove all painter’s tape from the project, and dispose of it properly. Using painter’s tape will result in a neat, consistent seam with little or no clean up required.

4.If using adhesive, test fit your work materials before applying the adhesive.

If adhesive will be applied to seams or edges of your work material, apply painter’s tape to all edges to prevent squeeze-out from getting on the surface.

Apply the adhesive to the work materials where they will be joined. Apply plenty of adhesive in a spiral or zigzag pattern and along all edges.

If edge trim is being used, install it now. Press the workpiece into place. If neces- sary, brads, nails, screws, clamps or bracing may be used to hold the workpiece in place until the adhesive dries.

5.If using fillers, secure the proper filler for the job at hand.

Remove any dirt, water or debris from the seam before starting work. Compressed air may be used for this.

If filling a vertical seam such as in a cement wall, insert caulk rod as needed in the seam. If filling a horizontal seam, such as a concrete floor, insert caulk rod or sand as needed.

Caulk rod is a foam rope-like product that is available in various diameters. Select the proper caulk rod for your application. If using sand, be sure it is clean dry sand.

Caulk rod and sand are used to reduce the amount of filler needed for a given job. However, filling usually requires a lot of material. This is why fillers are often sold in larger cartridges. It is a good idea to buy more than you think you will need.

When applying caulk rod or sand, leave enough open space in the seam for the filler to adhere to both sides of the joint and be thick enough to form a strong seal.
