SpecHard
GREENCONSCIOUS
Water-Based Siliconate Sealer / Densifier SpecHard is a water-based, odorless siliconate and silicate solution, formulated to penetrate freshly poured or existing concrete. Concrete floors that are subjected to excessive traffic can show signs of increased abrasion. SpecHard will create an internal matrix that seals and chemically hardens the concrete once it is properly applied. SpecHard is designed not to scratch, tear, peel or discolor. SpecHard leaves no film, and will not alter the natural profile of the concrete floor. SpecHard imparts a low glass, satin sheen with abrasion. SpecChem proudly warrants SpecHard against dusting for up to 20 years. Concrete surfaces treated with SpecHard exhibit significantly increased hardness and reduce water permeability over surfaces not treated with a liquid hardener. While not considered a chemical resistant coating, SpecHard treated floors are significantly more resistant to many commonly encountered industrial chemicals, gasoline, oil and other fluids. Dry shake hardeners provide excellent impact and abrasion benefits to concrete floors. SpecHard treated, dry shake hardened floors will reduce the maintenance costs over commonly applied acrylic based curing and sealing compounds. The SpecHard system is supported by a full line of chemicals and cement products for the concrete construction industry manufactured by SpecChem. Our history of over 250 years in the industry is helping to build the future. We welcome you to our family and value your support.

Application & Application Types Most applications are performed after the slab has been curing for a minimum of 28 days. Different specifications call for 14 days, 7 days and even 1 hour after concrete placement. The type of project, schedule and the owner determine which type of application is performed. These application types are: 1. Standard Post Seal – After the slab has been cured by another method. 2. SpecChem Pre-Seal Method – This is a compatible system that includes the curing compound and is applied the same day as the slab is poured. 3. Tilt-Up Application – This can be either Post or Pre-Seal method, but must consider the type of bondbreaker used. 4. Remediation – This is an existing slab that the owner wants stripped and wants SpecHard applied.

but in most cases additional material may need to be added during the scrubbing process. This is very common in exterior applications. SpecHard will begin to gel and the surface will become extremely slippery, a result of the SpecHard reacting with the free lime in the concrete. Continue working SpecHard into the substrate once it has begun to gel, a light spray of water to the surface may be needed. Do not flood the surface. This is why a garden hose is recommended. This is done to thin the material down to aid it in penetrating into the slab. Rework with brooms or scrubbers until material begins to gel again. Flood areas completely with water and squeegee off. Flood area completely again with water and squeegee off until completely dry. If residue remains on the surface, a third or fourth flooding may be necessary to completely rinse the slab.
All of these methods employ a standard process for the actual applying of SpecHard to the surface. They also use primarily the same equipment and staging techniques.
SpecHard Application Process The following steps are standard for applying SpecHard. These steps are used for both Standard Post Seal Application, SpecChem’s Pre-Seal Method, and SpecChem’s Bondbreaker and Pre-Seal System. These steps are used once the slab is ready to receive SpecHard. 1. Spray or dump SpecHard on the slab. Apply enough material so that the entire area is flooded. (In extreme heat, pre-wetting the slab may be necessary) 2. Using a push broom, swing scrubber or riding scrubber, move SpecHard around the slab. The surface should remain wet with SpecHard for 2040 minutes. Using the brooms or scrubbers, keep the material moving around the slab and gently work it into the pours. Keep the entire surface wet with SpecHard. By using the hand held pump-up sprayer, one person can keep adding material to areas that absorb the SpecHard faster than other areas. The brooms or scrubber will move material around, 866.791.8700 | www.specchemllc.com
