About Krack-kote

Krack-kote is a thick, pliable compound that surface dries but stays flexible underneath. Tuffglass Fabric is ultra-thin (.004") and creates a smooth, invisible bridge across the crack. The result is a strong, flexible patch that moves with your walls and ceilings. The patch is completely invisible under paint or wallpaper, and the crack stays covered up. . . for good!

What Causes Wall and Ceiling Cracks?

MOVEMENT!

You may not realize it, but all buildings are constantly moving. Temperature changes inside and out cause all building materials to expand and contract on a daily and seasonal basis. Outside forces like settling, vibration and freeze/thaw cycles cause buildings to shift and move. Moisture absorption and release make wood and other porous surfaces swell and shrink.

The Result?

Cracks occur wherever stress and movement is concentrated.

When building materials swell due to moisture or rising temperatures, cracks "close" and temporarily disappear. But, when temperatures and humidity levels drop and building materials shrink, those cracks reappear! There's no way to stop this pattern of movement.

Rigid crack fillers and spackling compounds try to solve the problem by filling cracks. When cracks open and close due to building movement, crack fillers crumble under pressure, or shrink, harden and fall out.

Krack-kote and Tuffglass Fabric is the only crack repair product that really works!

product benefits

Use Krack-kote and Tuffglass Fabric to permanently repair interior wall and ceiling cracks. Thick, pliable water-based repair compound. Krack-kote doesn't fill cracks, it bridges them with a strong, permanent patch. Surface dries, but stays flexible underneath to allow for building movement.

product features

Fast-drying, go from patch to paint in two hours. Never needs sanding. Finished patch is invisible under paint or wallpaper. Cracks disappear under patch and never come back.

Krack-kote 3-step Crack Bridging System

Surface Preparation: Surface to be patched should be clean, dull and dry. Don't dig out or fill crack. Make sure edges of crack are flush with surrounding surface.
Step 1: Don't fill, dig or cut out the crack. Make sure the edges and surrounding surface are clean and dull. Brush on a fairly thick coat of the Krack-kote over the crack and 2 to 3" on either side. Don't force the Krack-kote down into the crack - you're BRIDGING, not filling.
Step 2: Apply the Tuffglass Fabric, centering it over the crack. (Pre-cut the fabric to the desired length and trim any loose ends.) Imbed the fabric right into the Krack-kote using your brush or applicator tool. Smooth out all wrinkles, bubbles and excess material and feather the edges of the patch to blend into the surrounding surface. Wait 30 minutes, or until the patch has set-up and is no longer tacky.
Step 3: Brush on a second coat of Krack-kote. The Fabric should now be completely hidden. Smooth out any excess material and carefully feather the edges of the patch again. The patch is ready to prime in about 30 minutes - when the surface is firm and not sticky or tacky. Clean tools and brushes with soap and water immediately after use.

Application Tips and Special Techniques

1. Wipe your applicator or feathering tool frequently to keep it clean and free of clumps or dirt that may leave lines and streaks in the patch. A wet rag or cloth works well, and helps the tool glide easily over the patch. If the patch starts to dry too fast, moisten the applicator or the patch and re-feather.

2. If the fabric is still visible, or imperfections are evident after the second coat, apply another thin coat of the Krack-kote. The patch will be invisible.*

3. If you are patching a hole or "void" in your wall or ceiling, make sure those areas are flush with the surrounding surface before you patch with Krack-kote and Tuffglass Fabric. Krack-kote is compatible with all joint, drywall, plaster and spackling compounds and may be used under or over these materials.

4. When patching long, irregular cracks, cut the fabric into workable lengths and overlap the edges by 2 to 3 inches. Work carefully around these overlapping joints so the fabric stays flat and smooth.

5. Wide, structural cracks may require special treatment, as they reflect areas where stress and movement is concentrated. Using a wider width of fabric (5-1/2" or 12") or overlapping the fabric over the crack itself will provide a strong patch that can minimize the ongoing movement that causes these cracks to expand and contract. In severe cases, when the walls and ceiling expand, a bulge may develop along the center of the patch. This is the fabric wrinkling as the patch constricts in response to the movement of the surrounding surfaces. When the building materials shrink, and the walls and ceilings contract, the fabric re-expands and the bulge disappears. Patching the crack at its "mid-way point," when it is neither fully open or fully closed may prevent this phenomenon - using the wide widths of fabric will also help anchor the patch and spread the movement over a larger area.

6. If your wall or ceiling is textured, or has a special finish, the second or top coat of Krack-kote should be applied so it matches the surrounding surface.

7. Krack-kote can be used on all of the following surfaces: drywall, textured and smooth plaster, specialty finishes, stucco, wood, concrete and cement block.

8. Krack-kote should not be sanded, as it is formulated to stay pliable and surface dry only. If absolutely necessary, sanding can be attempted to remove imperfections or ridges once the patch has completely cured and set-up.

9. Before painting, make sure the patched area matches the surrounding surface in color, texture and degree of gloss or flatness. Make sure all paints have sufficient hiding power (opacity) and pigment to adequately cover wall and patch.

*Many Professionals and "Do-It-Yourselfers" prefer to use two thin top coats, and will extend the Krack-kote several inches (or more!) beyond the fabric edges to obtain a smooth, even finish.
