Directions For Use
Before you start:
- StoneLok "2K" requires skilled application. Practice your application technique on sample projects before use on a "Real" project.
- Read all of the RJSC's technical data sheets, application instructions and follow all of their post-application instructions.
- Parts "A and B", the concrete to be sealed, and the site temperature, when mixing, during application and during cure, must be between 65º and 85º F.
- Site humidity must be below 60% and have good air circulation.
Product, substrate and site temperature, when mixing, during application and during cure, must be 65º- 85º F., with humidity <60%, and with good air circulation (typically box fans are required) for normal cure.
One Unit = 3 Containers. Identify the bottles. (They are shipped in correct mix ratios.)
- A = Resin Part “A” [waterborne resin] larger bottle
- B = Catalyst Part “B” [curing catalyst] smaller bottle
- C = Water
Directions must be followed exactly.
- Pour Part "B" bottle into Part "A" bottle.
- Shake vigorously for 5 minutes. The mix must be totally blended!
- Wait 30 minutes for Gloss, Wait 15 minutes for Accelerated Product, then after this 30 or 15 minute wait...
- Add 1 Bottle supplied Water. [NOTE: If product or air temperature is over 80°, contact RJSC for induction times].
- Shake vigorously again. Pot Life is about 2 hours. (1 hour for Accelerated).
Apply as a thin, even coat --- typically less than 4 - 6 mils wet film thickness [~30 - 35 sq.ft. per 12-oz. unit. Application looks like a thin layer of no-fat milk, the appearance is “foggy-hazy”, never white.
Use HVLP sprayer with minimum 50% overlap; or use paint pad or short-nap roller (3/8” or less) as follows:
Visually measure off an area about 4' X 4' (2’ X 2’ for counters)
- Load roller and create a "V" OR “W” in the above area.
- Do not pour product onto surface.
- Working in a pull/push mode (away from you and towards you), quickly spread the material. Work with a free hand. The idea is just to spread the material evenly.
- Lightly back-roll. Do not overwork.
- Repeat the above adjacent to the first area, overlapping the new "V"/”W” slightly into the old.
- You want to work very fast so that overlaps are wet to wet.
- You want the look to be "hazy foggy" -- like no-fat milk -- never white. If there are any white spots (from drips, too heavy application, etc) immediately roll out. White spots that are left will cause the C02 produced in the curing process to become a white, crispy styrofoam on the surface. This can sometimes be sanded down and retouched --- but it’s better not to make the problem.
Cure conditions: The water must leave the film for cure. Movement of air speeds cure time by removing the pillow of moist air that forms as the water leaves the coating. In closed, "air-off" jobs, or if the air will be turned off within the first 12 hours of cure, it is very important to have box fans blowing about 2' - 3' up and across the surface to maximize the cure speed and final resin density; and to ensure finish gloss as specified. [Significantly extended cure times due to lack of air circulation will result in higher gloss levels].
The material is typically print-free in 10 - 12 hours (6 - 8 for Accelerated). If needed for ongoing construction or transport, sealed surface can be covered with Kraft paper and Masonite about 15 hours after coating. However -- if covered prior to final cure (3 – 4 days) and especially if there is potential for humidity build-up or turn-off of air, you must uncover for the first 2 - 3 nights to allow for final cure; and re-cover in the morning.
NEVER COVER WITH PLASTIC!
It’s best to keep everything off the substrate for 24 hours (48 if possible) and final strength takes 3 - 4 days. For counters, it is best to allow 72 hours before exposure to chemicals or cleaning. THEN, clean only with RJSC cleaners.
Typical dry times above are temperature, humidity and air circulation dependent.
Notes on Multiple Coats: A second or third coat of StoneLok “2K” can be applied in 8- 24 hour intervals for high-use areas.
