SURFACE PREPThe principles for surface preparation for Dura-Kote Pigmented Epoxy WB are aligned with other coatings systems placed on concrete and remain constant; the substrate must be:
- Clean: The surface must be free of dust, dirt, oil, grease, paints, glues, sealers, curing agents, efflorescence, chemical contaminants, rust, algae, mildew & other foreign matter that may serve as a bond breaker or prevent proper adhesion. To remove coatings, paint, sealers, glue from concrete, etc. best results are achieved through diamond grinding or shot blasting.
- Cured: Any concrete must be cured approximately 3 days. Cement based overlays typically cure sufficiently within 1 day.
- Sound: No system should be placed on flaking or spalling concrete. If the surface is delaminating, or divots are present, then diamond grinding, shot blasting or other mechanical means should be used to remove the delaminating areas. Depending upon size of area, patching may be required prior to application of Dura-Kote Pigmented Epoxy WB. Flash Patch or Deep Level is an excellent choice for a patching product to complement the system. Refer to their respective spec. sheets. Also, cracks may require treatment: evaluate crack as static or structural to set expectation of treatment. Refer to spec. sheet on SCT-22 Crack and Spall Treatment.
Construction Joints in concrete may have sufficient movement to “telegraph” through the Dura-Kote Pigmented Epoxy WB. Large expansive slabs should have planned appropriate flexible caulks to allow for this movement and prevent bridging of Dura-Kote Pigmented Epoxy WB across either side of the construction joint.
- Concrete: For a proper bond, the surface of concrete must be opened up or roughed up to feel like 80 – 120 grit sandpaper. This profile is best accomplished through diamond grinding or shot blasting. Proper profile should follow the standard established by the International Concrete Repair Institute (ICRI) Technical Guideline no. 03732 for Concrete Surface Profile (CSP). The established profile is categorized as CSP-2 or CSP-3.
- Finish or Top Coat: Screen the preceding coat with a 100 grit sanding screen on a rotational floor machine. This screening will ensure not only a good bond between coats, but also eliminate any debris or dust that may have settled onto the preceding coat as it was curing. Follow screening with vacuuming. Follow vacuuming with a micro-fiber wipe with a solvent such as xylene or acetone. Listed below are some common systems requiring a Finish or Top Coat:
- Dura-Kote Pigmented Epoxy 100
- Dura-Kote Pigmented Epoxy WB
- Any other Dura-Kote specialty system
- Understand Moisture: While Dura-Kote Pigmented Epoxy WB is not vapor permeable, it has some remarkable characteristics, unlike nearly all epoxies:
- May apply upon fresh concrete as soon as three days after pouring and placing concrete.
- Withstands high vapor transmission rate, up to 13 pounds per 1,000 ft² (5.4 kg per 100m²) in 24 hours. This means it can be applied to concrete where more than a normal amount of moisture is present. Calcium Chloride test (ASTM-F-1869) will quantify the amount of moisture that is transmitted to surface of the slab. The moisture measurement is expressed in terms of pounds (kg) per 1,000 ft² (m²) per 24 hours. Measurements that are in excess of 13 pounds per 1,000 ft² (5.4 kg per 100 m²) over 24 hours are too wet for application. Follow directions of test kit manufacturer. Note that a measurement may be inherently flawed as it is a “snapshot in time”. A test serves only as guidelines.
- Provides a non-permeable vapor barrier, even in basements. hours are too wet for polyaspartic. Follow directions of test kit manufacturer
TEMPERATURE/CUREAvoid application on extremely cold or hot days or during wet, foggy weather. Basic rules include:
- Apply with ambient and surface temperatures ranging above 50°F (10°C) and below 90°F (32°C) and that will remain within ranges for at least 12 hours following application.
- Surface temperature must be a minimum 5°F (3°C) above dew point.
Dry to touch = 4 - 5 hrs. Dry to touch = 18+ hrs.
Light traffic = 16 hrs. Light traffic = 30 hrs.
Full cure = 5 – 7 days Full cure = 14 days
- Select appropriate PPE (personal protection equipment). Provide adequate ventilation. Refer to MSDS.
- Work across the narrowest dimension of an area where practical.
- Work to an exit from wet product.
- To track coverage rate for each kit, after establishing room dimensions, before mixing commences, place a short piece of masking tape on the wall to correspond to the “distance” one premeasured kit should cover.
Mask all areas requiring protection; product will stick to just about everything.Mixing and handling:
- Organize mixing station that neither has to relocate, nor block the progress of application. Staging is critical so that Part A and part B are not confused with one another or mixed too far in advance. Once A and B are mixed, the catalyzed product should be placed on the floor immediately. If left in the pail too long, product will cure at an accelerated rate rendering it useless.
- Mechanically mix part A with “Jiffy” style mixer blade for 3 minutes at medium speed to insure pigment dispersal.
- Pour 1 part B into 4 parts A. Note that kits are premeasured for convenience. Exercise care to avoid pouring product down the sides of the pail, as this will be difficult to mix.
- Mechanically mix both parts A and B with “Jiffy” style mixer blade for 3 minutes at medium speed. Jiffy mixer at medium speed will help prevent air entraining.
- You may thin Dura-Kote Pigmented Epoxy WB after it has been catalized with water up to 15% (19oz per gallon), to aenhance absorbtion when porous conditions require more penetration. Note thining may also reduce color hide.
- Pour contents completely out in a fairly long trail for application. Any unused portion left in the pail can cure at an accelerated rate rendering it useless.
- Do not leave pail upside down to drain onto floor. Any unmixed portion of A or B that may have accidentally been placed onto side of pail can now drain down onto the floor, creating a spot that will not cure.
- Clean out or replace mixing pails, mixer blades, and roller covers in a reasonable fashion, so that the chemistry of A and B remain consistent, especially over large projects.
- Spiked shoes are required throughout application
- Select spreader
- A squeegee or a roller ranging in nap size from mohair to 3/8” (9.5 mm) may be appropriate.
- Rollers should be premium quality with phenolic core.
- “De-fuzz” roller by wrapping tightly with masking tape and removing tape.
- Large areas may require 18” (46 cm) rollers and wider squeegees
- Spread product evenly over area. Areas adjacent to walls may be “cut in” by brush.
- Backrolling: After achieving the appropriate coverage, begin progressively backrolling Primer Coat. Roller covers will require replacing periodically to prevent catalyzed product from setting up on roller cover or contaminating more freshly placed material.
Note: Primer Coat may “stand alone” as a single coat depending upon application system selected, or applicator and client choice. Or a single coat of Dura-Kote Pigmented Epoxy WB may proceed to a Finish Coat of another Dura-Kote product as described later in this spec. sheet (see ladder chart above.)Top Coat
If the Primer Coat has cured dry to the touch, and is no longer tacky (refer to cure rates listed above as a guide) repeat all steps of application listed above. Planning, masking, mixing and handling, and application are identical in Top Coat.
If the Primer Coat has cured beyond 12 - 24 hours or if dust or debris has settled into it as it cured, it must be screened with a rotational floor machine equipped with a 100 grit sanding screen. Follow screening with vacuuming. Follow vacuuming with a micro-fiber wipe with a solvent such as acetone, or denatured alcohol.
Note: The Top Coat may complete the project, and does not necessarily require a Finish Coat (see ladder chart above.) However, for enhanced durability and chemical resistance, a Finish Coat may be selected. Additionally, a Finish Coat may become the “carrier” for slip resistant agents for areas that may become wet, oily, or greasy when brought into service.Finish Coat
There are several choices that have varying advantages for the Finish Coat:
- Dura-Kote Polyurethane SB (gloss) – high gloss
- Dura-Kote Polyurethane WB (gloss) – low VOC
- Dura-Kote Polyurethane WB (satin) – tone down the gloss
- Dura-Kote PFC-120 – quick dry
- Dura-Kote PFC-180 – quick dry, moderate build
If the Top Coat has cured dry to the touch and is no longer tacky (refer to cure rates listed above as a guide) repeat all steps of application listed above. Planning, masking, mixing and handling, and application are identical for Finish Coat.
If Top Coat has cured beyond 12 -24 hours or if dust or debris has settled into it as it cured, it must be screened with a rotational floor machine equipped with a 100 grit sanding screen. Follow screening with vacuuming. Follow vacuuming with a micro-fiber wipe with a solvent such as xylene, acetone, or denatured alcohol.
For specific directions on finish coat refer to the appropriate spec. sheet.Sacrificial Coat
A Sacrificial Coat is not required, but will add further protection to the finished product. The Sacrificial Coat may be applied at any step following a “stand alone” Primer Coat (see the ladder chart above.) SureFinish provides a protective Sacrificial Coat, a measure of slip resistance, and is available in gloss and matte, as a simple mop on product.Read More
