IT depends on the ambient air temp as to how fast it will evaporate after wiping it off. The key is to wipe it on then with some clean paper towels wipe it dry. DO NOT just wet it down and leave it to evaporate, you will have problems. Wax and grease remover ( if it's PPG brand) will not remove the base if you do not rub it excessively.

Don't use the standard Bounty or home paper towels to wipe it down. Some towels have inks in them for printing and others will leave lint and a residue. They do make a paper towel that you can get in packs from your local jobber for using the wax and grease remover. As far as a time frame. I have shot base anywhere from 15 minutes to a half hour afterwards. Just make sure you tack off the area before you spray your base but after you use the W&G remover to get rid of any possible lint debris.

 

Here is a little "Basics of Basics" on surface cleaners ("wax and grease remover")

I wrote this a few years ago so the part numbers may have changed but the info for use is still the same.

Degreasing

I just wanted to ask why you would want to degrease before you apply your base coat? I'm not sure what you are painting but I have found through experience that using a degreaser right before painting always gave me some sort of problem (I use a brand called Tumbler). Usually as Martinsr says this is done before anything is sanded to begin with. Now again through experience I found it best to clear over base before you tape, using something like DBC 500 blending clear seems like the glue on the tape and fresh base coat collide, sometimes I would shoot a coat of 2021 depending on what I was doing, especially with flames as I wanted a good base. Anyways hope this saves you some time.

 

Thanks, I am spraying 2 colors and didn't want any (sticky) from the tape to be left behind. I thought I could use wax and grease remover to completely clean the surface after the removal of tape.
Thanks !!

 

WHOA there Rodder1, you are planning on applying base, then taping and applying more base, then removing tape and clearing? Depending on the base, you MOST CERTAINLY don't want to touch that base with wax and grease unless it is water borne. It WILL attach most bases.

Yes you clean before you sand, but cleaning after you sand and before you base is needed as well. That is where you use a weaker, faster flashing cleaner. If you had problems with it, it was likely because you used a slow flashing or too strong cleaner that stayed behind on the surface and you buried it under the base.

I am not shooting Base on Base, I am shooting base on old sanded ppg 2021. I was always taught to keep the surface as clean as you can, I have always in the past painted one color, I was just wondering if I should clean the area where the tape was, or not using wax and grease remover.
Thanks !!

 

If your substrate is the clear, or any other cured film such as the clear then yes use a wax and grease remover. I thought you were asking about cleaning an un-cleared basecoat.
