Simiron 1000HS, 100% Solids Epoxy Floor Primer, Clear, 1.5 Gallon Kit

Surface Preparation: Concrete must be sound, clean, dry and free of contaminants such as dirt, dust, grease, oil, silicones and other contaminants that may negatively affect adhesion. Concrete should be a minimum of 28 days old. 

This product is intended for cracks up to 1/8 inch in width , but larger patches can be made with this material. Remove all unsound concrete from within the crack/defect to be repaired and thoroughly vacuum all debris and dust from within the crack opening.

Moisture Vapor Barrier: A suitable moisture barrier must be in place for concrete slabs on-grade. If a moisture barrier is not in place, seasonal variations in ground moisture can cause excessive moisture vapor transmission (MVT) regardless of results measured prior to coating application. For 16 mils of 1150FC, MVT rate must not exceed 12 pounds per 1,000 square feet per 24 hours, as directed by ASTM F1869. The relative humidity (RH) of the slab must not exceed 85%, as directed by ASTM F2170. If there is a moisture situation in excess of the above rate, the use of Simiron MVB Moisture Vapor Barrier Primer may be required. Consult a Simiron Representative for details and application procedures.

Application: 1000HS Primer mix ratio is 2 Parts Base to 1 Part Activator by volume.

1. Pre-mix Base at low speed for 1 minute with mechanical agitation. Pour base into a 2—5 gallon mixing pail. If pigmenting, mix U-Tint into the Base. Then, add Activator and mix for three minutes until uniform with mechanical agitation. Do not mix more material than can be applied in 10–15 minutes (material will stiffen or tack-up).
2. Immediately pour all mixed 1000HS Primer on the floor in a long bead approximately 8–12 inches wide. Do not attempt to roll material out of a bucket or roller pan. 
3. Wearing spiked shoes, spread evenly at 3–8 mils by pushing a flat squeegee or metal spring blade along the bead. Overlap previous passes in order to ensure concrete pinholes are filled. A tight, thin coat of primer with no backroll is the best way to minimize outgassing bubbles.
4. If back-rolling, use a non-shed 3/8 in. roller and back-roll the primer evenly across the squeegee passes to minimize application lines and leave a consistent film thickness.
5. After the 1000HS Primer has set, inspect the surface for evidence that the substrate is not sealed. If pinholes are not completely sealed,  outgassing may occur. If necessary apply an additional coat within 24 hours to ensure uniform coverage before applying the basecoat. 

Dry Time: Open working time: 30-35 Minutes, Tack free: 10 Hours, Light Foot Traffic: 24 Hours, Minimum Recoat Time:  6 Hours, Maximum Recoat Time: 24 Hours, Full Cure: 5 days, all subject to ideal surface & air temerature with relative humidity of 72°F (25°C) 50% RH. Ideal temerature range for application Air Temp: 45°–95°F,  Surface Temp: 45°–95°F, Material to be applied: 60°–85°F. 

Coverage: 200-533 Sq. Ft. per gallon applied 3-8 mils thick. Use a mil gauge to make sure of proper application thickness.

Clean Up: Clean up mixing and application equipment immediately after use with acetone or xylene; do not use alcohol. Follow solvent manufacturer’s safety instructions. Be sure to follow all local, state and federal regulations when disposing of materials.
