Thread: Spray can lacquer

Jovian not sure this will help but my local Bunnings sells Bondall in a spray can. It is marine grade. Monocel Gold Marine Grade Clear Timber Varnish

It is still poly tho.. Hmm.. Thanks anyway

The spraycans of clear for car paint are an acrylic lacquer, if that's what you mean.

To strat with if you want anything serious..forget bunnings or any other hardware chain store.

Mirrotone, an manufacturer of commercial and industrial laquers makes a precatalised nitroceluolose laquer in pressure pack cans.

From memory carbatec and some other wood work shops stock it.

Septone, and automotive chemical company make a clear laquer in a spray tin....not sure if it is acrillic or nitro...seem to think its nitro.

Clear acrillic laquer can be purchased at any auto re-finish supplier..some may still have nitro.

As for compressor and spray gun........the cheapes you could go and still ge something workable would be $200 ish......$100 will buy you a small compressor, $75 will buy you a cheap but not horrible spray gun ther reast you will spend on hose and fittings.

cheers

It's definately an acrylic.

Wonderful reply!! Thanks!!

Anyone heard of 2 parts lacquer? It seems like a damn fine quality lacquer that has this ultimate smooth touch! Just went to wood show today was so impressed with their product

A two pack (or two pac) will be a polyurethane based product with an added isocyanate as a catalyst to kick off the setting reaction.

You don't generally want to be spraying iso-based products without heavy duty safety gear - full face mask, coveralls, pressurised air supply (not just organic vapour filters). To get good off the gun gloss (from any finish) you need a good spray setup.

On the subject of two pack (and without wanting to hijack the thread) there some locally made resin called Glass Coat. Does anyone have any experience working with this?

It looks tempting in theory but I'm a bit paranoid about what would happen if you had less than pristine application and drying conditions and how you'd get rid of any minor imperfections, their whole selling point being it gives a (presumably pretty unforgiving) glass-like finish (hence the name, I guess - their marketing people weren't sleeping in class).

The glasscoat, pourongloss, aristocrat type products are not laquers or varnishes, they are pouring epoxies, or as we would say in electronics "conformal coatings"

They can indeed produce wonderfull finishes, bu yess indeed there are issues you have to address.

They are slow setting epoxies, that is how they can flow out to that smooooth glassy finish.

BUT...OH HELL YEH..dust is a major problem, the guys who do a lot of this stuff have clean rooms or drying cabinets set up to deal with the dust issue.

Some of them are also very finiky about temperature and humidity.

too hot and the resin is too runny and it wont build..it all just runs off, too cold and it wont flow and the bubbles wont rise.

A couple of other problems with the humidity range.

So you either have a thermometer and hygrometer and pour when the stars align or ya set up a airconditioned room with a humidifier.

Then there is the fumes issue......like all epoxies the fumes may not kill you but they will give you a roaring headache in the short term and give you brain dammage in the long term.

Is it the fumes problem is true? I didn't ever realize that!

Fumes are definitely an issue with all epoxies and most two pack products.

Even the best personal air filtration is marginally effective.

Some of the modern epoxies are designed to reduce the amount and toxisity of the fumes, but they all produce fumes.

For the hobbist, the best management is small quantities of material and very strong airflow.

If I'm working with the stronger smelling epoxies I work with my roller doors open and a fan at my elbow blowing across me and the work into the open air.

some of these epoxies will give you a roaring headache if you do not take precautions....similar to you get from welding galvanising with out precautions.

cheers

Appreciate that so so so much sound man!! I was wondering why I got this real bad headache after I'd uses epoxy!!
