Products : Surface Prep : Waterproofing Membranes & Underlayments : Crack Buster® Pro Crack Prevention Mat Underlayment
A self-bonding, fabric reinforced, asphaltic membrane that isolates ceramic and natural stone tile from cracks in the substrate. Suitable for both full and partial coverage applications. CrackBuster Pro is a crack isolation membrane that meets the requirements of ANSI A118.12 and protects tile from in plane movement up to 3/8” (9.5 mm). Its strong self-adhesive backing and uniquely designed surface provide secure bonding for all types of ceramic, natural stone and terrazzo tile. CrackBuster Pro also helps reduce sound transmission through the tile assembly.

Installation must comply with the requirements of all applicable local, state and federal code jurisdictions.
Crack Buster® Pro is an elastomeric, fabric-reinforced mat underlayment, with modified asphalt and a polyurethane adhesive.

Exterior and wet areas must have proper sloping to drains. All surfaces must be structurally sound, clean, dry and free from contaminants that would prevent a good bond. Newly prepared concrete must be troweled smooth and textured to a fine broom finish and cured for 28 days. Existing surfaces must be scarified and leveled, and all defects must be repaired. Cracks exceeding 1/8" (3 mm) should be treated in accordance with TCNA F125 or TCNA F125A.
Expansion joints and cold joints, as described in ANSI A108.01, should never be bridged with setting material. They must be brought through the tile work and filled with an appropriate elastomeric sealant, such as Custom's 100% Silicone. Contact Custom's Technical Services for the proper treatment of control or saw cut joints. Refer to TCNA EJ171, F125 & F125A.
Wear impervious gloves and eye protection while using this product. Avoid contact with eyes or prolonged contact with skin. Wash thoroughly after handling. If eye contact occurs, rinse cautiously with water for several minutes, remove contact lenses if easy to do: continue rinsing. Immediately seek medical advice if symptoms are significant or persist. Do not take internally. KEEP OUT OF REACH OF CHILDREN.
Gypsum substrates must exceed 2000 psi (13.8 MPa) and must be fully sealed using Peel & Stick Primer.
Plywood floors, including those under resilient flooring, must be structurally sound and must meet all ANSI and deflection requirements. For questions about proper subfloor installation, call Custom® Building Products.
Resilient flooring or plastic laminates must be well-bonded, as well as clean and free of all contaminates. Roughen the surface by sanding or scarifying; rinse and allow to dry. Do not sand flooring that contains asbestos. For existing well-bonded ceramic tile, mechanically abrade the surface. Rinse and allow to dry. An approved respirator should be used when sanding.
Thick accumulations and powdery, brittle or weak cut back adhesive layers must be removed. Use extreme caution, as adhesives may contain asbestos fibers. Do not sand or grind the adhesive residue, as harmful dust may result. Never use adhesive removers or solvents, as they weaken or soften the adhesive and may cause it to penetrate into the concrete. The remaining residue should be no thicker than a coat of paint and should be almost transparent. Always install an adequate number of properly located test areas.
Application of Primer
For proper adhesion and optimal bond, prime the substrate with Peel & Stick Primer. Using a paint brush, short-nap roller or soft-push broom, apply an even coat and allow it to dry until tacky to the touch, about 30-40 minutes. When the primer does not transfer to your finger, the surface is ready for application of CrackBuster® Pro.
Full Floor Application
With the release sheet still attached, unroll and position the membrane over the area to be treated and cut the membrane to the appropriate length. Roll up half of the cut membrane, leaving the other half in position. Cut the release sheet from the rolled-up portion of the membrane and pull the membrane into position, exposing and unrolling the self-stick portion. Return to the unrolled portion of the membrane and follow the same procedure. Check the positioning; smooth wrinkles and bubbles with a flat trowel and roll with a 50 lb (23 kg) roller or apply 50 lb (23 kg) of pressure with a hand roller to ensure complete contact with the substrate. Air pockets and wrinkles should be slit then smoothed with a roller or the flat side of a trowel. Align subsequent sheets and butt-join the seams tightly but do not overlap them. Clean tools with soap and warm water.
Crack Isolation Application
With the release sheet still attached, premeasure and cut the membrane to the desired length. The membrane should extend 6"-8" (15-20 cm) beyond the length of the crack in both directions and should extend beyond both sides of the crack and at least 3 times the dimension of the tile used. Reroll the membrane and center it over the crack. Remove about 2" (5 cm) of release paper and apply it firmly to the substrate. Remove the rest of the release paper, exposing and unrolling the self-stick portion of the membrane. Secure the membrane to the substrate with a 50 lb (23 kg) roller or equivalent heavy pressure from a hand roller or flat trowel. Remove fresh adhesive from tile surfaces with a damp cloth. Clean tools in warm soapy water.
Install tile or stone with a Custom® Building Products polymer-modified mortar that meets ANSI A118.4, A118.15 or A118.11 standards.
Clean tools and hands with water before material dries.
Store and transport in a cool dry area.
Properly installed product requires no special maintenance. Do not use as a wear surface.
