These times are based on a 3.1 mm dry film thickness
Higher film thicknesses or cooler temperatures will require longer cure times
If the maximum recoat times have been exceeded, the surface must be abraded by sweep blasting or sanding to produce a rough surface and to remove the "scum" layer before the application of any further coating
Remove all dirt, loose paint, spalling concrete, rotted wood, marine growth and other contaminants by abrasive blasting or high-pressure water blasting.
Hand or power tool cleaning methods may be used but are of limited benefit and are time consuming.
Abrasive blasting can be done underwater as the initial air blast will clear a path through the water for the abrasive/air mixture.
When working at the splash zone or in salt water, coat cleaned metal surfaces as soon as possible to minimize new corrosion.
Application Methods
Product Information
Mixing:
Mix one Part A to one Part B by volume. Mix by hand "scooping" a quantity of the "A" component from the can and then "scoop" the same quantity of the "B" component from its can. Mix and knead the two components by hand until the yellow and black colours have combined to make a uniform olive green colour.
Apply this mixture immediately after mixing; no sweat-in time is required.
To assist in mixing, keep the gloved hands and the materials wet with water during the mixing process.
Thinning:
Not recommended. Use of thinners other than those supplied or recommended by Carboline may adversely affect product performance and void product warranty, whether expressed or implied
Pot Life:
Working times at 21°C, below and above water: Golfball size mix: 40 minutes baseball to softball size mix: 30 minutes ½ gallon mix: 15 minutes. Working times are reduced by one-half at temperatures above 27°C.
Do not mix more material than can be applied in the working times listed. The material may still appear to be workable after the time limit is exceeded, but it will not properly adhere to the substrate after application and curing.
General:
Apply by hand, trowel, or broad knife. Spread material smoothly onto the surface in a 3.1 to 6.4 mm thick layer using enough pressure to displace water and air bubbles. Smooth out the area by hand. When starting another mix, start spreading at and away from the previous applied film. This will help prevent trapped air bubbles or leaving an area uncoated. If applying to dry surfaces in dry air, periodically rewet hands, or tools with water to keep the product from sticking.
When used as a patch or grout, force the material into the hole or crack and smooth by hand to the thickness needed. For larger patches greater than 12.7 mm, use a steel or fiberglass plate for added support. Apply to the substrate, then embed the support plate (cut larger than the hole) and apply product overall.
When applied under water or when wetted with water during application, the surface will form an emulsified lighter green "scum" layer. This layer is normal and facilitates application. The film under the "scum" layer remains undisturbed and will cure properly. The "scum" layer will cure and become part of the finish when it is cured above water; however, this layer will remain soft and uncured when the product is kept underwater during curing.
