Concrete Repair Kit – 100% Solids Epoxy Crack Filler, 1:1 Mix, Fast-Setting Professional Grade Patch for Cracks, Holes & Surface Defects in Concrete Floors & Walls

Simiron 800CF is a professional-grade, two-component epoxy crack filler engineered to repair damaged concrete quickly and permanently. Designed for contractors and serious DIY users, this 100% solids repair compound fills cracks, holes, gouges, and surface defects to create a smooth, structurally sound surface prior to applying floor coatings. Unlike thin repair materials that shrink or sag, Simiron 800CF features a thickened, easy-to-control consistency that works on both horizontal and vertical surfaces. The simple 1:1 mix ratio allows fast preparation, while its rapid gel time enables efficient repairs without slowing down installation schedules.

• PROFESSIONAL-GRADE CONCRETE CRACK REPAIR : Simiron 800CF is a two-component, 100% solids epoxy crack filler designed to permanently repair cracks, holes, pitting, and damaged concrete on both horizontal and vertical surfaces. Ideal for preparing floors prior to epoxy, polyaspartic, or polyurea coating systems.
• FAST-SETTING & EASY TO USE (1:1 MIX RATIO): Simple 1:1 mix ratio by volume makes application quick and straightforward. Thickened formula stays in place without sagging, allowing easy placement using a putty knife or trowel. Gel time of 2–3 minutes with a workable application window for efficient repairs.
• STRONG, DURABLE STRUCTURAL REPAIR: 100% solids epoxy formula delivers high compressive strength (8,710 PSI) and excellent adhesion to concrete (350 PSI with concrete failure). Creates a rigid, long-lasting repair that resists shrinkage and supports heavy-duty coating systems.
• HIGH COVERAGE CONCRETE REPAIR: A 2-gallon complete kit repairs up to approximately 2,456 linear feet of 1/8" x 1/8" cracks, making it ideal for large floor preparation projects. Actual coverage will vary depending on crack width, depth, and surface conditions.
• FAST RETURN TO SERVICE: Walkable in approximately 24 hours with full cure in 5 days under normal conditions. Many coatings can be applied immediately after placement for narrow cracks, helping contractors maintain fast project timelines.
• WIDE RANGE OF APPLICATIONS Perfect for: Garage floors Commercial & industrial concrete Warehouses & manufacturing facilities Basements & workshops Vertical masonry repairs Surface defect patching before coatings
