    Well I just vacuum cleaner it with a brush end, wipe with cotton cloth (usually old T shirt!) which has been dipped in the solvent used for that paint. Then just before applying wipe with clean bare hand, this seems to take off those last little flecks that even compressed air does not blow off.

    You can actually feel the odd 'bit' with your hand but often sighting along the surface shows little or nothing.

    The oils in you hands can cause issues, though not so much with alkyds, the water bornes can be a real prick in this regard.

    :rolleyes: Vacuuming was so obvious that I didnt do it.

    I did think of double sided tape on a roller, but then worried about leaving sticky goo left on the surface from the tape.

    I have four more doors to do, so I will benefit from the good advice.

    Pars suggestions about sanding afterwards worked well for one door, but it was too much work for just a domestic job, that I didnt tell the missus that it was an option for the other seven.

    You can get a thing called a "tack cloth" specifically designed to remove dust and debris from surfaces that are about to be painted. They are are sort of "sticky" and will attract debris like freshly dry-cleaned dinner suit. Most auto paint shops like Ardens should have them, maybe even Bunnings and Super Cheap Auto. The advantage of using a tack cloth is that it will not leave and oils etc that might effect your finish and it will not stir up more dust like the exhaust from your vacuum will. Also, a tack cloth will probably work better than a vacuum because quite often I find that a vacuumed surface will still have a fine layer of dust - depends on your application whether this is an advantage or not. Tack cloths are pretty cheap and certainly worth a try.

    I use tack cloths and I've never seen a clean hand, well certainly not one that works as well as a tack rag. Admittedly, I'll run my less than clean hand over work, just before I tack, which finds a surprising amount of junk. I think we all can agree, you just have to work neat and clean for paint jobs. The more quality you expect, the neater and cleaner you need to be.

    Yes, the tack cloth is a great idea. My shop vac could be put outside the 'tent', but its not a quality unit.

    I really want a clean room, with insulated walls, oh - and perhaps a fresh air supply ..... oh and some heat lamps would be good ............

    And instead - what you have is a 120 year old shed with a dirt floor....

    Hi Pointer, its also worthwhile trying a "flat" brush they apply paint and tip all at once. get one that is suitable for your paint solvent. They produce an excellent smooth finish very quickly. Peter

    I've built on site paint booths for very little money and effort. Some 1x2's, clear plastic sheeting, some staples if you like, a box fan at one end and an pleated A/C or furnace paper filter at the other end. Tape the fan and filter to an appropriately sized hole and use a slit or flap door. It draws in filtered air and blows out over spray, dust, etc.

    I have a 'plastic and old sails' tent set up that keeps the worst of the dust off, but I might make a better quality effort when I varnish the two kayaks in the near future, along the line of Pars suggestion.

    I have a friend who is champing at the bit to hire the shed for glassing up two boats - so he may need a 'finishing booth' toward the end as well.

    On this recent painting effort, I used the tack cloths - and noticed a huge reduction in those annoying little flecks, as hoped.

    Of course, the local tiny black fly population took exception to that, and sacrificed a few of their virgins on the great white altars so carefully prepared for them. :(

    They thoughtfully deposited three bodies on three of the four door panels, to make sure that the 'shed god' would not fail to notice their offering.

    never mind, a bit of polishing will get rid of the small carcasses , and a new can of flyspray will reward the elite class of small black fly rulers for their efforts.

    I noticed that with a little bit of thinning of the paint that I had to load up the roller a lot more. It would only work on horizontal surfaces.

    Tipping off brush

    If proper tipping off brushes arnt available a good quality chip brush works fine for tipping.
    Foam rollers work best...be sure they are poly compatible if using two component.

    Paint should be very thin...use slow thinners and catylast for long flow, work time.

    Cheap brushes, especially chip brushes are only good for sweeping dust off a work bench. They'll leave hairs all over the work and generally are worth the price you paid.
