Hi guys,
I need a spot of advice. Like alot of us I have a less than ideal garage, which is the usual damp, home resto garage. I am working on the underneath, and doing small sections at a time. I use epoxy primer (lechler 29107).
I have only a few hours to work every few evenings (i.e Mon, Thursday, Sunday) or something like (i.e Mon and Tues (back to back) then Friday, then a Tuesday etc). It changes due to kid duties!!
Temperature and curing/drying....heat panel then heater?
Can I heat the panel before I paint with a heat gun, then use a heater on the panel while drying....but then leaving the paint to air dry afterwards in what is realistically going to be a cold British winter home garage!!! If it matters, my plan is just small sections at a time (i.e 6 inch by 6 inch)
If you read the datasheet, it clearly says 60 deg C for 30 minutes at low bake (in an spray oven) or not less than 15 Deg C for air drying....but if i heat the panel to 60 deg C, then keep a heater on it for 30 minutes after I spray (with the aim of keeping the panel at 60....would that work? is 60 deg C too hot to get a panel with a heat gun, less? more?
Once its lights out each evening, the garage temperature would drop like a stone, the usual British climate we all know....still ok? I am working on the theory that epoxy primer is basically water proof, but I am not sure that will apply after just one coat and possible condensation a few hours later?
Shall I just give up and move on to a different primer, like an etch primer from a spray can or etc? Or shall i just leave it all to next summer, and find something else to do with this winter? I would rather do it now, but if it will be a losing battle, perhaps I need to come up with another idea, like maybe heating the garage for a few days!! realistically this is unlikely
If it matters, I could heat panel with heat gun, paint, heat panel directly for 30 minutes with the paint drying on then put another coat on and repeat....maybe one more based on the air brush idea below....all in one night??? bad idea???
Airbrush?
I have a HVLP machine (apollo 700) which sprays the lechler well. I want to however work on small sections at a time (i.e 6" x 6") as an evening would consist of cleaning the old stone chip then, scrubbing off the old stone chip, rust buster DTS/Chlorex, then MBX and phoskleen B, followed by final water rinse, then heat gun dry and then a coat of primer....which for a 6 x 6 inch section is easily 3 hours particularly if any rust....
So I like the idea of a small gun like an air brush with a 0.8mm tip? So there is not loads of solvent and paint, fumes etc. Just a quick mix up, spray and gun clean, rather than the full set up of the HVLP
Or based on the above (either, all or both!!), shall I just give up on the idea, and stick to either a spray can etch primer, or hand paint with a different brand, etc...?
