EVOLVE SERIES: SOY BASED STAINS FOR CONCRETE SURFACES

RECOMMENDED TOOLS AND SUPPLIES: Sprayers should be of High Volume Low Pressure type (HVLP). Low speed floor buffers with red and black pads can also be utilized as an optional application method. Manual application needs include 16 inch floor coating nylafoam pad, 18 inch paint tray, lightweight t-bar floor applicator, low nap rollers, or sponges. Other materials that may be needed include a pressure washer, commercial wet/dry vacuum, floor fans, painters tape, rags, spray bottles, shoe covering, and spiked shoes.

INSTALLATION-TEST AREA: Concrete and cementitious overlays will vary greatly on composition, hardness, porosity, and finishing methods. Therefore, establishing an absorptive, open surface profile is necessary for proper stain penetration and performance. A hard troweled or machine finished surface that has a highly smooth dense surface can sometimes resist even the penetration of water. These types of surfaces must be treated to establish an open profile which has sufficient capillarity to absorb the stain. A small test application should always be made on the surface to be treated. This should be performed preferably in an area that is unobtrusive and not in the main section of the job-site  since stained surfaces are permanent and will usually have to be ground down to remove the stain if the test area is deemed insufficient. The test area should subsequently be applied and sealed in the same manner as instructed before approving the color and proceeding with full scale up to the entire project.

NEW CONCRETE: Finish in accordance with ACI specifications and allow to cure for a minimum of 14 days, however a time of 28 days is preferred for best results. Curing should be by water misting only, surface applied curing compounds should not be applied since they will inhibit the penetration of the stain.

OLD CONCRETE: Surfaces must be clean and free from oil, paint, wax, sealers, curing compounds, related surface stains, rubber marks, dirt and laitance. Use Concrete Earth Clean & Prep C-20 Detergent or Enviro Clean & Etch C-30 for removing grease, oil, or rubber marks, taking care to rinse the surface completely with potable water afterwards. The use of a green floor stripper such as Concrete Earth® Lightening SB is recommended of removal of existing paint or coatings. Use plastic tarps around surrounding surfaces, structures and plant vegetation to protect against Evolve™ Stain overspray or contact. Evolve™ Stain will react differently on older or worn substrates and will not typically show as strong of an effect as on newer, more absorbent surfaces

SURFACE PREPARATION: Concrete to be stained should darken and be able to absorb water when dampened. Some hard troweled, burnished or overly polished surfaces may not absorb water, therefore, they may have to be lightly sanded or abraded to open up surface capillarity and allow stain penetration. Surfaces should exhibit an open profile as previously indicated. Test the surface for sufficient porosity by spraying a light water mist over the work area. If the water soaks in quickly and easily, then the surface is considered adequate for staining. If the water tends to bead up on the surface or does not seem to penetrate, then the surface is either a non porous hard troweled type or possibly there are existing sealers or contaminants such as cure and seals, sealers, densifiers, or hardeners or other contaminants like oil or grease that are blocking the water. Optional removal methods include sanding, grinding, or shot-blasting which will allow maximum penetration of the Evolve™ Stain. Another option is to use Overlays or Speccrete® Microtop Overlay which can be utilized on stable substrates to create a new, light colored surface that will allow full penetration and benefit of the Evolve™ Stain. These overlays should be allowed to dry out for a minimum of 4-5 days before applying the Stain.

STAIN APPLICATION: Sprayers: Application sprayers should be adjusted for a fine mist spray. If using an air compressor, suggested setting range is 20-25 psi for fine mist. Invert and gently shake OCERA Evolve™ Stain containers several times to eliminate any settlement that may have occurred over time. Apply with a plastic or metal sprayer in a small circular motion, or by use of a stiff bristle brush in between spraying to aid penetration into the substrate. Sprayers can provide a more even finish when used alone, whereby brushes applied in circular motions can create more varied and mottled appearances.

MANUAL APPLICATOR: If using manual methods such as a 16 inch nylafoam pad with 18 inch paint tray, apply the OCERA Evolve™ Stain in 3 foot passes moving right to left and working the stain into the surface evenly. Work out any lap marks by continually working the stain into the surface. It is very important to always keep a "wet edge" on the applied surface, take care to avoid dry laps where wet stain overlaps dried stain. For lighter colors, the Evolve™ Stain can be diluted with water up to 10% by volume with water. For slightly darker hues, apply an additional coat within 1 to 2 hours of the first application. Use thin coats, do not apply in excess! Do not leave application bucket or tools inside the stained area as they can leave permanent imprint marks on the surface. Do not wash off stain in between coats if a second application is desired for darker effect.

DRY TIME: If the OCERA Evolve™ Stain has dried in excess or too quickly in hot applications, spray the area with water and rub the stain into the surface as soon as possible from time of application. If the stain is allowed to dry this way, these marks will be very hard to remove at a later time. If there is Stain that has not fully penetrated the surface, the use of a buffing machine with medium to coarse (blue, red or brown pads) can be used to help work the excess stain into the surface.

RINSING: No wash down or neutralization step is necessary after stain application. NOTE: The color of the wet surface will look similar to the finished appearance after application of the sealer of choice. Contain the area from pedestrian traffic and allow to dry using circulation fans to speed the drying process.

SEALING: OCERA Evolve™ Stain will require typically 4-6 hours of dry time before applying a top coat sealer such as Concrete Earth's Envirosheen. Apply two coats of Envirosheen for automotive or high traffic areas to provide maximum protection, allowing 1-2 hour dry time between coats. Allow the Envirosheen to dry for approximately 10-12 hours before opening the area to pedestrian (foot) traffic. Allow 5-7 days of cure before opening to vehicular traffic, taking care not to expose the surface to excess water or chemical cleaners during this cure period. The fully cured Envirosheen will exhibit excellent hot tire pick up resistance.

SPECIALTY FINISHES: For added slip resistant finish, add Spec Grip Slip Resistance additive into the topcoat of the sealer. Our B-40 CR Floor Coat Epoxy coating can also be used for a more durable, chemical and abrasion resistant finish. Follow sealer instructions on both product data sheet and label. Prevent pedestrian traffic for 48 hours and 4-5 days for vehicular traffic. For interior applications, it is recommended to topcoat the sealer with a high gloss floor polish such as Concrete Earth's Diamond Shine Polish, which acts as a renewable wearing surface that will extend the life of the sealer while providing additional protection and easy maintenance.
