Could you confirm how long is needed between coats? Is it necessary to wait 24 hours or can you put a second coat on once it has tacked up slightly to eliminate the need to flat with p600? Thanks
If you are spraying with our ultraspeed, you have a 20 minute flash off time, so you can wait 20 mins and re-coat! If you wait longer than this you will need to wait the full 24 hours to denib and then re-coat. If you are using coach enamel it is recommended you wait the full 24 hours.
Also, I've learned the hard way, ensure you have sufficient flow rate for your gun measured in CFM. HV is high volume and that means air volume delivered to the gun to atomise the paint. Without this you'll likely get orange peel. If it requires 14 CFM at the gun you need to account for loses from the compressor through the valves, oil/water separator, line and connectors - go for the high flow connectors. Or, go for a LVLP spray gun designed for small low capacity compressors.
Thanks Paintman, really useful 👍
Glad you found it useful! :)

@@paintmanpaint perfect thank you 👍
Is it 24 hrs between primer and first coat of enamel too?
It is yep, so it is dry enough for you to key before your top coat :)
Hello. What psi do you recommend, is 1.3 tip hvlp gun ok. Thanks
Hi! You want around 40psi, you would ideally want a tip of 1.4 - 1.6. We use a 1.5 tip here! :)
