I am in the process of lacquering a couple of carbon fibre parts and have acquired a 2k clear lacquer aerosol from Spray Max. Before I start spraying what sensible precautions should I take within reason? I have a P3 nose and mouth mask, gloves, safety glasses and intend to spray in the garage (I plan to heat the garage before spraying). Probably only need one tack coat and two wet coats and each coat should only take a couple of minutes max. Appreciate your advice please. TIA.
Hold your breath. Should only take very short time to spray each coat, get it on not too heavy and then leave the room until ready to do next coat. Assuming that you have no way of rigging up any sort of extractor.
Not sure you can have 2K in a can. It is made up of a 2 part system (resin and hardener). If it's premixed in a can it will just go off to a solid mass. Anyway, when painting 2K you should be wearing a positive pressure air fed respirator. It's dodgy stuff containing isocyanates. It's not for the home hobbyist paint sprayer. http://www.hse.gov.uk/construction/healthrisks/hazardous-substances/isocyanates.htm
^^ @Robarano have to admit I am nervous about using it but it is available as you can see. I have read some scare stories hence asking for advice. This stuff is meant to be the best you can get in an aerosol but I don’t want to harm myself for a nice hard finish (no double entendre meant). Has anyone used this product?
Jack, if you don't have it already this may help a little https://download.kwasny.com/datasheets/TMB-680061_GB.pdf and here is the MSDS https://download.kwasny.com/datasheets/SDBREZ59_-_Aerosol_2K_Klarlack_GB.pdf Edit after Chris' advice on temp from the 680061 advice sheet Optimum application at 18°C - 25°C and a relative humidity from 40 - 50 %.
not sure what a P3 is R but if it's the very efficient one with twin filters that i'm thinking of, then i'm sure it will be fine, just don't stay in the environment for longer than you have to (as said). I think there are at least two professional sprayers on here, but can't remember their "handles". On a less serious note - do you have to do it at this time of year? - even if you get the temp high enough you might still have some moisture/humidity instability issues that could affect the result a little. @Red998 ?
Yup, I have a twin filter mask - P3 I believe relates to the protection level - P1 lowest, P3 highest. I don't have to do it now but I want to - I might wait until it warms/dries up a bit outside though!
Lacquer in cold/humid can keep the moisture trapped inside and it goes kinda foggy. You can clear it with a hair dryer but it's a PITA. Having pissed about like this to many times I now just pay a pro. You can get 2 k masks on eBay.
I do normally pay but my body shop must have thought they seriously undercharged me last time they did work for me, as they are asking what I consider a lot for this small job. And I fancy having a go myself TBH.
CF can be a b*rstardo to prep with the small surface (pin holes) that are full of stuff that reacts badly to every type of spray. When you have cleaned 100 times, do it again.
