Most producers of pavement sealers recommend a minimum of two tenths of a gallon of sealer per square yard for two coats. Simply multiply the square yards of pavement to be sealed by .20 to determine the mixed gallons of sealer to be applied. Your mix design will determine hhow many gallons of concentrated sealer, water, latex and sand you will need. Please check out the product calculator on this website, or you can go to our website, gemsealinc.net for assistance, or feel free to call me if you have any other questions.

I think all manufacturers now have websites you can visit to check out mix designs. You can find our mix suggestions at gemsealinc.net. Most producers will recommend standards that are within the ranges you listed in your message. The mix designs you mentioned are good but you may want to include applicatin rates in your specifications. Is the contractor going to apply one coat or two, or a third coat in the drive areas, and at what application rate on each of the coats? Remember, two thin coats are better than one thick coat and the more time you can give between coats the better your coating will perform. Also, you may want to ask to see some of their jobs that are a year old and actually go and check these jobs out.
Mike , some oil stains are so heavy the only way to handle them is to cut out and patch or treat with an ifrared box. Typically if you can take a screw driver and penetrate the surface easily your sealer will not bond. If the pavement is sound try cleaning with soap and water to remove as much oil as possible just remember to flush the surface really well with clean water. All soap must be removed or you will be creating another oil spot. You may also want to try flash burning (very, very llightly) the surface with a propane burner, then apply an oil spot primer that is recommended by your sealer supplier. If these things don’t work you will have to patch the area.

Unlike parking lots and driveways, highways are constantly re-compacted by continuous traffic. Highways are also not subect to the continuous attack of petoleum derivatives in the same areas.
Slurry seals, chip seals and micro seals all have their proper applications, but parking lots and driveways, in my humble opinion, are not the place for these applications. On parking lots and driveways use only coal tar or asphalt emulsion seal coats.
The info you are asking for could take awhile. Can you call me and we can spend as much time discussing this topic as you would like? I can be reached at 404 234 7102.
Give me a call at anytime if you are still having problems. I can be reached at 404 696 7660. ask for Harry Carter.
Several things can cause thte surface of your coating to develop this chalky appearance. Landscaping chemicals washing from the gras is possible as well as water staining from sprinklers, it could also be concrete staining from curbs and gutters. If your sealer had a slow cure from lack of direct sunllight or was applied in cool or cold weather you can also get a graying of the coating. A simple test of the surface will tell you if the staining is on the surface only. Wet a cloth with clean water and scrub the surface. If the surface turns black then you know somethling has stained your coating.

You may want to try a product called OIL-FLO, most manufacturers and distributors carry this material. When you are trying to remove sealer from a surface make sure you first apply a small amount on an out of the way area. You want to make sure you don’t compound the problem.
Make sure you check with the manufacturer for their recommendations but I think you will find that all emulsions, coal tar and asphalt, should have sand added.
I think all producers of asphalt and coal tar sealers recommend the addition of sand. Any coating that is applied without sand can be slippery when wet.
I have never seen RS90 applied, but apparently this is a rejuvenator type sealant that has an asphalt base. I would not feel comfortable commenting on a material I am not familiar with. It might be a good idea to ask for job locations where this coating has been applied and if you can inspect a few locations that are a couple of years old you can make a reasonable comparison on wear.
