• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

I am faced with a humungous painting task in the house and thought about spraying. No furniture. No problem !

The paint manufacturer site says



and so what sort of kit do I need, please ?

Hire or buy ?

TIA
 
I would be looking at a HVLP set up with a large cap and tip set... Around 1.8 to 2.0mm so you can get more (solid content) through the gun without thinning, especially with emulsion and waterbourne finishes. It might be worth hiring (or buy and flog on) an industrial set with a large capacity as with the standard guns you'll be filling the quart cups a lot and this could become frustrating and you'd be likely to get in a mess quickly... or at least I would. (Gummed up seals, pressure cup valves, etc)

I use a Fuji HVLP, though I hear good reports on the Earlex sets which are very affordable.

It's certainly a good idea if you've plenty to do and you're unfurnished.

Fuji HVLP here too. Don't think I'd try it indoors but it is certainly better than high presssure spraying for overspray/ fine airborne paint mist. I have sprayed large areas with it when giving the shed its treatment, way faster than with a brush but you do cover evertything.

The turbine supplies hot air which is another factor that help you spray thicker paint than conventional spray.

The knack with spraying is knowing when you have a full coat and not going so far as to have runs. White on white comes down to guesswork / experience on the second coat.
 
You Pros out there wouldn't consider a Wagner outfit for us DIYers as a one off investment within a DIY job.

Rebuilding my kitchen extension, I had to get emulsion behind the floor standing boiler in an alcove and the 'squad' of vertical pipes behind it.

I dismantled all the boiler casing, masked the boiler gubbins and flue, and used a Wagner to spray everything. I had tried a brush, but missed loads around the back of the pipes, and rubbed painted stuff with arms and hands. The Wagner didn't and it was an even coat all over.

British emulsion needs thinning a lot. Watching the Wagner vids, the continental emulsions are much thinner to start with.

Mission Control was well pleased with the result!

I might be using the Wagner to paint the inside of the 'shop! Well, actually, I will!
 
I would also go the HVLP route.

My set up is a high pressure compressor which is lots of overspray and a fine 'dust' that gets in everywhere - everywhere and oh yes everywhere! :oops:

Just from a coverage/number of coats.

With spraying you can apply a number of light coats building up to a final finish with no runs 8-)
Just keep the gun moving all the time.

I have got a monster graco setup for painting and spray plastering. It is seriously quick for panting large areas but the amount of prep and masking is hard work plus you need to be able to deal with over spray and watching edges to other colours.
To be honest if you are just doing a couple of rooms you might as well just hit it with a roller.
 
Thanks, mj. It's the whole house...over 1000 sq m to paint. Any room is all the same colour. Nothing on the floor worth worrying about so just the windows.
 
You will use more paint in the sprayer than by roller. The graco takes 5 litres just to prime the machine. Watch the tip size to get a wide fan without getting tails.
 
I used one of my dad's Graco 1395s to do mine and the finish was incredible.

Again as above masking is crucial as it's very high PSI, but overlapping fans mean double coating in one. also the 'bounce back' is more or less dry if it falls more than a few feet. I loved it and for large areas wouldn't use anything else.
 
I recently bought one of these HVLP units,

for spraying smaller stuff, it is such a hassle firing up the compressor and the cleaning up afterwards.

I have now used it for spraying some of the cupboard and bedroom doors with a PU (mixed in pre-cat) and the finish looks good. (Son & DIL house)

Less mess than the compressor, easier and faster to clean up.
There are 2 spray nozzles, one for thin stuff like a PU and one for thicker stuff like wall paint.
It also has an airflow adjuster, and the front turns to change the spray pattern.
(not suitable for spraying cars)
