Parking Lot striping on older worn asphalt: On these surfaces striping can be done all the way up to 100-115 degrees.  There is a very low chance of any kind of failure due to extreme temperatures.  However humidity is the big striping paint killer.  If humidity gets above 80% there is a good chance failure can occur.  Check the weather before working in humid conditions.

Parking lot striping on freshly sealed asphalt: There is a relatively low chance of failure on this type of surface due to high degree temperatures.  However be cautioned that the sealcoat it self can become very unstable when applied at temperatures over 105 Degrees.  Our experience has shown us that sealcoat starts to become unstable when applied at temperatures above 110-115 degrees.  It may be smarter for sealcoat to be applied at night in desert like areas throughout Southern California.

Parking lot striping on freshly laid asphalt: When it comes to fresh asphalt you have to be careful as to when you stripe it.  Fresh asphalt is a surface that is curing out oils and chemicals to the surface and because of this you will get some odd side effects.  If you do parking lot striping on asphalt that has just been laid, most times you will get a brown marking that occurs on the white lines or yellow lines you stripe down on it.  The best solution to avoid this is to stripe the asphalt after it has had a few days to cool down.  Most contractors however don’t do this because the parking lot is typically needed as soon as possible.  One solution to this problem is to stripe it once and then return a week or two later to re-stripe it.  This is a good solution mainly because new asphalt is porous and requires two coats of paint to get a good finish on the lines.  So the first coat of paint will get the markings down for traffic and pedestrians (though stained brown in some cases ).  The second coat of paint will hide most if not all of the damage caused by painting the lines over the fresh asphalt and at the same time the second coat of paint will give a nice even and full finish.

So there is your summer time striping tips for the Southern California area.  If you have any questions or comments please post below.  If you have a project coming up in the near future then just shoot us a call.  We would love to hear from you today.
