Spraying help pleeease - again!

Thanks Steve - would you say it's too cold for the Chestnut Melamine Lacquer too? What problems do you get with lower temperatures on the non- water-based stuff so I know what to look out for if the temperature gets lower? I'm spraying in the shed I built recently - so indoors - but no insulation or heating and have the door wide open.

Bit puzzled why you're all thinning the Melamine Lacquer - it's much less viscous than the water based stuff? Is there another reason aside from the viscosity?

Will try Osmo or Chestnut equivalent at some stage but spraying is quick when it goes well!

Robert - hand cream! My wife saw that and laughed! But I do need to be careful with contaminants - thanks. Now sanding the shop counter and am also concerned that perhaps the patchy'ness may be due to heavy sanding on the delicate veneer?? Perhaps these bits don't take the lacquer so well?

Well even though I had success with the spray gun and compressor yesterday on the counter shelves my Earlex HV5000 arrived today and I gave it a go. Wish I'd gone this route in the first place - what a doddle! Very impressed so far. Got a perfect finish off the acrylic lacquer straight off - the controls are so straightforward compared to using a compressor. The only negative I can see so far is the constant noise! But will give a further report when I do the big spray - a nice SATA RP gun could be for sale shortly!

Cheers

Glad to hear you like the melamine lacquer - its a great product.
And also pleased you got on with the Earlex, a lot of machine for the price. And an idiot can use it - I'm living proof :lol:

The problem with low temp and high humdity is that of "blooming". As the solvent evaporates its chills and any water in the atomised finish (now on the job) condenses and forms a white bloom, which is virtually impossible to get rid of.

You need warm and dry.

I'm glad you are getting good results, but rather surprised in this weather.

Thanks Steve - don't think that's what I was getting although reading up on it it does sound a worry. I've got to do a big piece today - so too early to say I'm getting good results yet!!

. Yes the Earlex has only really has one control other than fan shape (fluid control) - compared to the compressor / SATA gun which has at least 4 others! Plus length of hose, possible contamination in hose (water, oil), power of compressor, capacity of compressor ...
