Applying international paint

slimtim · 25 April 2006, 12:06

I will shortly be painting my console with international brightside gloss paint. I have just been into my local Delux store to look at trays, rollers and brushes but was told by the bloke in there that there may be a chance that the polyurethane based marine paint may react with the high density foam roller resulting in it degrading (the rollers are suitable for use with water/oil based paints).

Has anyone had any experience of using high density foam rollers (delux type or I guess those available from DIY stores) with marine paint...specifically international brightside one pack polyurethane? Do I need a special roller?

Many thanks.

For an area as visible as a consol, I'd personally spray it. With good prep and primer it would look perfect. It depends on what kind of finish you're looking for.

I'm looking for the finest finish I can achieve but don't have the facilities/time/money to spray it. Apparently good surface prep, careful application and "tipping off" can produce very good results so thats what I'm aiming to do...in theory!

Tim, first used a roller for gloss paint at Xmas and now all the time. Put it on thick and it doesn't leave lines like a brush. Used both foam and long haired rollers with gloss and the foam gives a better finish just need to do the final pass slowly or tiny bubbles will remain. Given the cheap cost of 7" rollers and the small area you are doing I wouldn't worry about them.

Do you not want to used the two pack paint which gives a harder finish?

I have just painted a 8ft tender with the same product used fine wool miny rolers from dulux
I have found that the foam ones sometime brake up

Just done the same Tim: painted a console in Brightside with a foam roller. Very pleased with the finish; good prep is the key as is taking your time....

Harris foam roller sleeves last longer than others in 2 part paints for some reason.
A roller will give you the best finish and the highest build of paint per coat if you can't create perfect conditions for spraying .
The foam is eventually efected by 2 pack paints and laquers so just throw the sleeve away after each coat , that is if you even need 2 .

If you notice the foam of the roller starting to swell and feel softer then its starting to degrade.

If you are not happy with the finish wait a few days for it to fully harden then a fine rubbing compound to polish it smooth .

thanks for the replies chaps.

Pete, I'm going to use 4inch high density foam rollers and then get a nice expensive "tipping" brush to gently take out any orange after (international say do this) and to paint the bits the roller won't reach.

I have ruled out using the 2 pack system for the following reasons (feel free to sway my decision if you think i'm making a mistake!):

1. The brightside is half the price
2. The brightside is easier to apply
3. The 2 pack needs mixing (so needs measuring cups etc) whereas the brightside doesn't.
4. The brightside is much easier to touch up if it chips or rubs off.
5. Its easier to get a higher quality finish with the brightside

The only advantage to the 2 pack I can see is that it is harder wearing, but I think the brightside will be ok.

Tim, I would be intrested to know how many coats of undercoat/top coat you used and if you have any tips?!

GRUMPY, I think I'll go for a large pack of foam rollers and chuck em as soon as they start to go odd on me.

Thanks for the help!

I would disagree with using a brush to top off the paint .

If you work the paint well into the roller in the tray before you begin to use it any air bubbles will be pushed out . There is a very slight orange peel finish with a roller but it looks much better than brush strokes and is easier to polish out .

Warming the paint up will also help to get a better finish and most of the orange peel will flow out .

Also don't paint it on a hot day or in direct sun as the paint drying too fast initially will prevent it from flowing to a smooth finish .

As with a brush the last roller stroke should be very lite with no pressure on the roller

Tim, I gave it two undercoats (precote) and tinted it with a bit of briteside to get a better colour. Obviously sanded it between each coats. I then gave it 7 (I think) top coats; very thin, and again sanded between each one. I found it much easier (and you get a nicer finish) if the paint is warm. On cold days i put the pot in some warm water before I started; seemed to work!

On hot days you also tend to get lots of little insects sticking them selves to your lovely paint job....

Make sure you use thinners, the paint is designed to be thinned to the appropriate amount. It's definitely worth using International thinners. I can't remember which one it is for brightside I think its thinners No333 but it maybe 3. Tim M should know as he got his from me! Pretty sure the No.3 is for antifoul off the top of my head. And yes B&Q budget rollers are fairly useless in my opinion

Tim M · 25 April 2006, 21:47

its 333 for brightside. It doesnt need thinning if its nice and warm.

Perfection, Rollered on, 1200 wet and dry, and buffed. No polish, yet.
