Roklin's Pavement Repair Frequently Asked Questions
Friday FAQ 3
In our 18 years in business we have had some questions that get asked on a regular basis. Below are some of those questions (and answers). For other questions, please contact Brett Barnett at email@example.com or 877-FLEXSET.
Q: Is there a minimum depth required?
A: You want the product to be applied at least 1/8 of an inch, preferably 1/4 inch. If using topping sand (as recommended), please allow room for sand placement so as to keep your repair flush.
Q: You recommended that FloMix or FlexSet should be applied above 60 degrees. Figuring I'm spreading it to 1/4-3/8 inch, how long would it take to set up at temperatures below that?
A: FloMix or FlexSet would take about 40 minutes to set up at a temperature of 60 degrees. A 50 degree temperature would give you approximately 1 hour to set up. Catalyst can be purchased to speed the cure time in cold temperatures.
Q: I have a low spot just inside my garage doors. Can I just build it up a little and screed it level, or would you suggest roughing it up with a masonry blade first?
A: You can buildup your low area with our FlexSet material. FlexSet is self leveling and you can use a concrete trowel to feather out the material to meet the surrounding concrete. It is not necessary to use a masonry blade. FlexSet will adhere to the existing concrete, if dry and clean.
Q: how much does a 5-gallon bucket of FloMix weigh?
A: A FloMix bucket weighs 54 lbs.
Q: I have a depression (birdbath) in my driveway that I just sealed. I poured a five gallon bucket of water in it to see how much FloMix I would need to order. It looks like I'll need approximately 6 gallons. I'd like the repair to look as neat as possible by blending in to the existing driveway. I have two questions: (1) If I buy 2 3-gallon buckets, is it ok to let the first one cure and then apply the other the next day? (2) Can I tape off the birdbath to a neat square and successfully float the product, then remove the tape or is there a better way to achieve a neat finished appearance?
A: Keep in mind that FloMix comes in 3-gallon and 5-gallon kits. That means that the kit arrives in a 3-gallon or 5-gallon bucket, not that it fills 3 or 5 gallons. I see how this can be misleading. The coverage is approximately .4 cubic feet. You can use aggregate and fill it in lifts, but there is no need to wait between buckets. You can wait if there is some kind of constraint, but it is not necessary. The material cures in about an hour. You can tape the project off with duct tape and it will look much neater.
Q: We live in New Mexico where the concrete does get hot enough to fry an egg. In the summer months the concrete also remains quite warm 24/7. How do your crack repair products hold up to the heat? We have some large cracks in the driveway and right now we do not have the money to replace it.
A: Our crack filling material has been used in the southern California desert, where temperatures can get upwards of 120 degrees. It has held up for three to five years in this extreme heat and on highways with heavy truck traffic without any problems.
