Description

  • Americrete’s Crack Repair Procedure is a flexible product designed to fill cracks and joints prior to resurfacing with Americrete’s Concrete Resurfacer. This procedure is a quick and efficient remedy for crack repairs.

General Information

  • Structural cracks are caused by many factors, including subgrade problems, insufficient expansion joints, tree roots, insufficient steel reinforcement, or insufficient concrete thickness or strength for the intended use. No crack repair system is 100% effective and structural cracks may reappear. Pre-stressed concrete uses cables to keep cracking to a minimum, but post tension slabs may still crack. No warranty that a crack may reappear.

Surface Preparation

New Floors

Any new concrete shall be allowed to cure for 28 days.  Pressure-wash the surface with a 3000 P.S.I. pressure washer in order to remove any residue or alkali buildup prior to the application of Americrete. 

Surface Preparation of Existing Coated Floors

Remove all existing coatings, sealers, curing agents and other foreign materials by shot blast or grinding equipment in order to reveal porous concrete. Remove the contaminated materials and dispose of in an approved disposal site.

Crack Repair System

  1. Cracks should be V-grind, clean and free of any debris or other fillers prior to the application of Americrete. 
  2. Cracks are to be primed with Americrete Concrete Bonder Admix A-300. 
  3. Cracks should be filled with Americrete Waterproof Basecoat A-900 mixed with Americrete Bonder (A-300).
  4. Mixing ratio will consist of: 1 Bag A-900 to a half gallon of A-300 and a half gallon of water.
  5. Additional water can be added to achieve desired consistency. 

Structural or moving cracks should be covered with the addition of Americrete Flex Mesh A-1600.  After the crack has been repaired and dried, apply Americrete Flex Mesh A-1600 and Americrete Concrete Resurfacer A-600 over the crack and allow it to dry.
