Stontec ERF Product Data - Stonhard - #2

Stontec ERF is available in 12 standard colors. Refer to the Stontec Color Sheet. Custom colors are avail­able upon request.

Proper preparation is critical to ensure an adequate bond. The substrate must be dry and free of all wax, grease, oils, fats, soil, loose or foreign materials and laitance. Laitance and unbonded cement particles must be removed by mechanical methods, i.e., abra­sive blasting or scarifying. Other contaminants may be removed by scrubbing with a heavy-duty industrial detergent (Stonkleen DG9) and rinsing with clean water. The surface must show open pores throughout and have a sandpaper texture. For recommendations or additional information regarding substrate prepara­tion, contact Stonhard's Technical Service Department.

The use of Standard Primer is necessary for most applications of Stontec ERF. The Standard Primer must be fully cured prior to application of the Undercoat.

Application of the Stontec ERF system is accom­plished as follows:

1. Standard Primer is mixed and then applied to the floor with a squeegee and a nap roller. The Stonshield aggregate is broadcast into the wet primer. Allow 8 hours to cure.

2. Stonshield Undercoat is mixed and then applied with a squeegee and rolled with a medium nap roller.

3. After 5 minutes, begin broadcasting colored flakes and continue until a complete and even layer is bound to the Undercoat. Let cure until the surface is tack-free. Sweep off excess flakes and prepare the area for application of Stonshield Sealer.

4. Apply the first sealer coat immediately after mixing. Stonshield Sealer is applied using a rubber squeegee and a medium nap roller.

5. After the first sealer coat has cured, sand the sur­face with a rotary sanding machine. Vacuum the floor and apply a second sealer coat in the same manner as the first.

Refer to the Stontec ERF Directions for further detail.
