Scofield - Formula One Dye

Concrete should be a minimum of 28 days old, and readily absorb sprayed acetone. Surfaces to be dyed must be dry, free of evaporation or surface retarders, concrete curing compounds, form release, coatings, sealers, oils, waxes, laitance, or any other material that might prevent dye from penetrating the surface. If any of these inhibitors to penetration are present, dry scrub
or grind off these materials with rotary equipment. If power washing or wet cleaning is needed, is needed, allow surfaces to complete dry before application of dye.

If preparing to color concrete that will be later polished, grind the concrete to the desired aggregate exposure and profile prior to application of dye.

The following 8 steps have proven successful for floors in a wide range of conditions.

1. Grind or open the surface to the desired level of aggregate exposure. This may require rotary equipment. Finish with 400 grit abrasive disks or pads.

2. Remove dust by vacuum.

3. Mix dye and acetone as directed.

4. Apply the SCOFIELD® Formula One™ Liquid Dye Concentrate mixture. This can be done with an acetone resistant low pressure garden sprayer, mop, or brush.
Apply in a circular motion to just saturate the surface. Second coat or complementary colors can be used at this time.

5. Allow surfaces to dry. This will take 30 minutes depending on weather conditions.

6. Remove surplus dye. Use rotary equipment with stiff bristle brushes or fine honing 800 grit abrasives to remove excess dye and expose desired aggregate surfaces. Remove any dusts with vacuum.

7. Lock in dye with densifier or sealers/topcoats. Follow application instructions for these products. If using solvent based products, apply 1st coat with spray equipment to avoid lap lines and roller marks.

8. Proceed to polishing if desired.

Coverage will vary depending on the porosity and texture of the surface, surface preparation, and application technique. Typical coverage rate is 300–600 ft2 per diluted gallon (7.0–15 m2/L). Additional coats willincrease color and opacity.
