Rust-Oleum Watertite Polyurethane Sealant is the best wall crack repair products. It is particularly made to seal cracks in walls, seal dynamically moving joints like expansion and control joints/cracks, filling deep cracks and holes, tilt-up panel joints, precise concrete panel joints, curtain wall joints and perimeter caulking to windows, doors and panels. This polyurethane sealant can be used for concrete block, stucco, cast-in-place concrete, exposed aggregate and slump block, and more. This polyurethane sealant is ideal for using on basement walls, fountains, window doors, cellar walls., planters, canal, retaining walls and more.

Features of Watertite Polyurethane Sealant

  • Seals and waterproofs joints/cracks in walls.
  • Long lasting flexibility.
  • Ideal for filling deep cracks.
  • Excellent adhesion – does not diminish over product life.

For best results: Use cement tools to make sure firm contact with the joint interface.

How to Seal Cracks in Walls with Watertite Polyurethane Sealant?

Prepare Your Surface

This is very important task which you should before applying sealant. The joints surface must be free from dust, dirt, oil, and loose particles. The joint must be sound, clean, and dry. Possibly, the surface may require scraping or wire brushing in order to remove loose mortar or previous coating.

Design of Joint/Cracks

Watertite Polyurethane sealant maybe used in any vertical or horizontal joint in accordance with accepted architectural/engineering practice. Joint width should be 4 times the anticipated movement, but not less than ¼” (6.4 mm) wide.

Dimension of Joints/Cracks

For joints ¼” (6.4 mm) to ½” (12.7 mm) wide, the width and depth ratio should be equal. Joints that are ½” (12.7 mm) wide or greater should have a sealant depth of ½” (12.7 mm). Minimum joint size is ¼” by ¼” (6.4 mm by 6.4 mm).

Application of Polyurethane Sealant

To achieve best result, atmosphere plays an important role therefore it is recommended to apply when the temperatures of surface and air are between 4-49°C. It is strongly recommended that the temperature of material should be at least 10°C before use. Colder material will require more effort to dispense material from the cartridge. Insert Polyurethane Sealant tube in a conventional caulk gun. Cut the plastic tip on an angle to the desired opening size. Puncture the foil inside plastic tip. Dispense the material into cracks. Apply to cracks ½” wide or less. Cracks over ¼” in depth must be filled with backing material or filler before applying Polyurethane Sealant. Use a putty knife to level and smooth the surface. A topcoat can be applied after the sealant has cured for 72 hours.
