Sinmast Mortar and Grout Redi-Mix units are furnished in ¼ and ½ cubic foot units which contain all materials required to complete a standard mortar and grout formulation. After thorough blending of all materials furnished (epoxy resin, hardener, graded aggregate), material is ready to be placed with standard hand tools. Redi-Mix units can be used to make repairs to chuckholes, spalls, wide cracks or used as a topping to change the elevation of piers, machine pedestals or foundations. The material can also be used as an extremely strong, and fast curing grout system for anchoring or supporting machinery. The system has excellent resistance to calcium and sodium chloride and most known de-icing chemicals, road oils, gasoline, mild non-oxidizing acids and alkali products. The material has excellent abrasion resistance and non-skid properties.

Advantages / Features

• High-Strength
• Stronger than cementitious grouts
• Easy mixing pre-measured kits
• No Shrinkage
• Bonds well to most dry surfaces

Uses
As a high-strength grout and patching or repair of worn or deteriorated surfaces. SINMAST #303 is ideal for use in:

• Machine Bases
• Patching and Resurfacing
• Anchoring & Chocking
• Joint Nosings
• Precision Grouting
• Rail and Sole Plates

1. Concrete surfaces should be clean and dry and metal surfaces should be sand blasted to “white metal” finish for enhanced adhesion.
2. Mix the Part A Resin and Part B Hardener according to packed ratio for 2-3 minutes until streak free.
3. Use neat resin as a primer at 125 s.f. per gallon on existing surfaces for enhanced adhesion.
4. Add in pre-packaged aggregate or 5.5 parts of approved aggregate/sand mix to one part of mixed epoxy resin until thoroughly coated. Immediately place and finish grout with screed boards or trowels. Blend in more sand/aggregate for thicker mixes and use less sand/aggregate for more flowab!e mixes
5. Clean tools or uncured resin mix with water or mild solvents.
