please forgive my ignorance here but can anyone explain the "tipping off " during the painting procedure for me.
 
Ideally done by a second person following behind (esp if the paint is applied with a roller) using a brush to produce a nice smooth finish. Just rolled on an left will tend to have a slight stippled appearance

Tipping out is a very light brushing out with a really good quality brush (ideally used a few times before to really smooth out the ends of the hairs) to get rid of the stippled effect a roller on its own produces, or the lined-grooved brushmarks putting paint on with a brush leaves. Very very light pressure when "tipping out", use tip of brush only, brush at maybe 30 degrees to surface.

You do this whether you first apply paint by brush or roller, and it flattens and evens out the paint film to get a better finish. Can only be done within a minute or two at most, preferably within seconds, of the paint being put on the surface. Leave it too long you'll make the finish worse, hence the ideal being one person with roller, another following with brush. Done reasonably well you get a good finish, real experts (not me) can make brushed on paint look like a spray finish.
 
Let it stand for 20 mins after mixing, that should eliminate the bubbles.
Use mohair type rollers, the white plastic ones just rot awat immediately.

Hi, I am about to paint my deck/cabin roof with International Perfection and the guy on the Internation Paints technical helpline said use the white dense foam rollers that you can get in B&Q etc. that push on a mini roller handle. He did say that they will only last 20 mins before disintegrating and need changing!

I have also found a cheap source of good quality short pile (4-5mm) mohair rollers that can be cut in two to fit a smaller 1 1/4" roller frame.

Will the mohair leave a reasonable finish that can be tipped off using disposable foam type brushes?

P.S. A search on ebay will find foam brushes for as little as 30-40p each in bulk, as opposed to £2 in the chandlers! Quality is the same.
 
I have found tipping off with bristle brushes to still leave marks. I have always used the exhausted roller, before re-charging, to just ghost over the paint I've applied in a downward direction.
If you've thinned the paint correctly for the temperature and humidty it should remove roller marks and contine to flow out to a nice gloss finish.
I suppose the foam pads do the same really.

The mohair rollers are fine, however the cheap foam brushes are useless, the bubbles in the foam are too large resulting a jagged tip; look for the high density foam brushes and keep a rag with some thinners on it handy to wipe the foam clean.

Worth while having a play with Jenny Brushes to tip off. With the two pot paints, they tend not to leave "brush marks" and are as cheap as chips!

If it's worth doing it's worth doing well.
I will only tip off with Badger brushes ( as recımmended by Awlgrip) or Omegas.
Cleaning is a bit of a palaver but worth the effort.
Still using one 15 years later.

Anything with xylene in will rot cheap brushes and rollers alike. I have found some expensive mock mohair rollers to be next to useless and cheap foams to work fine, it is all in the manufacture. I buy cheap foams, and If they are good, they get used for finishing, if not they get used for oil based paint
 
Hi,
we use Harris small white foam rollers and jennybrushes with a bit of thinner added to the two pack paint. The foam swells up and comes apart after a while so you have to work quickly. Quality brushes can be cleaned with acetone if you want to try that route.

Be careful with good brushes, acetone isn't always the answer.
Use the brush cleaner recommended by the paint manufacturer.
Expensive I know but better than ruining expensive brushes.
Also invest in a brush spinner and use it each time.
Why not use the correct roller rather than **** that falls apart?
Cheers,
Chris
