Hull painting with Roller and Tipping

[Rustic Charm]

guys, I'm intending on painting a red stripe along the toerail, similar to this one in this Teleport picture. I'm using two pack Vintage Green and I think the red is called Tolopea or something like that.

Do I put the green on first and then the up higher red? or Do I don the Green last so I don't accidentally put any other paint on to it.

Also, the shop owner told me I need to line up the two colours using tape, because if I put 'red over green', then it will be quite high where the join is. But, can i really line up the tape well enough to make the join disappear?

Personally, I'd paint the whole boat green first then tape off the area you want to paint red and paint it. The difference in height will be negligible (based on two coats being applied).

The last thing you want is to paint the red and green, only to peel away the tape and find you have a nice primer line visible!!!

PS - re: mast height - we've increased our sail area to 100sqm, but that's what a 15t heavy disp boat should have anyway to get even the slightest bit of performance. Our main is pretty small, so we run under jib & mizzen, hoisting the main and genny as needed...

I'm right with you!

White boats are boring.

I love our red boat, but Sally keeps trying to convince me to paint it white. Not a chance!

BTW, it's looking good, and yes, if you fair in any dents you find now, you'll just see the next lot.

That's exactly what I was worried about

I would paint the green first with the 2 coats overlapping on to the red stripe area, then mask with 'fine line tape' (with 1" blue tape over top but set back a touch.
Then wet sand the green before over painting with red

If you do this the water will trash your tape. Dry sand and then scotch brite to the tape line.

You are right Minaret....(i should never post at 3am

What's the dry sanding for?

So the next coat will stick.

Ok, just to take the sheen off a bit

Am I not going to end up with quite a 'lip' with two coats of the red on top of the green?

[ausnp84]

You might not need to sand - check with the paint supplier. I know our paint was good for 7 days before a quick sand was required to give a mechanical bond.

There'll be a slight lip, but not noticeable. When I did the non-skid on my boat, the sections that had non-skid applied (then two thick overcoats) are slightly raised, but it's pretty negligible.

I'm awake now....will try to explain more clearly

For topcoats.....I like to wet sand with 800 so that as you sand you can feel the paint surface for any blemish while keeping the fine dust negligible as you are continually washing.

First and 2nd topcoat green, overlap stripe line slightly and mask with blue tape only before painting. You wet sand in between and replace blue tape.

Same with Red, but as this is your Final Line you add fine line tape to your masking line and replace with new after wet sanding.

From this photo, if you zoom in, you can see that I am only using blue tape while slightly overlapping the Boot Strip.

The danger of keeping a hard line at stripe is the sheer stress on edge that can break down the adhesion and gloss as the boat gets repeatedly washed.

[Reefmagnet]

Car guys use a special scotchbrite style pad for roughing up paint prior to overcoating where the underlying paint is in good condition. Stealing again from the car guys, the edge between paint colours can be covered with a pin stripe if there's any bleed through or raised edge deemed unacceptable.

So, like this ?

wet sand
blue tape
paint

next day remove tape,

wet sand
blue tape
paint

? Was this right?

Is fine line tape a special tape? Is it still blue? and what do you mean with ýou add fine line tape to your masking line and replace with new after wet sanding' ?

What's a 'hard line' ?

[Pelagic]

I remove the blue tape AFTER I have wet sanded the top coat and replace with fresh blue tape before applying a 2nd coat.

Fine line tape is a plastic tape that gives you a very precise and thin edge.
It is narrow so as to take a radius so you use blue tape behind the edge to give you a wider protection.

3m makes it and this video shows what it looks like

A hard line means a raised paint edge.
