Biting the bullet (respray)

[Strathglass]

I have finally given in and have decided to spray the topsides.
At long last my 'home build ' is nearing completion.

I have spent many weeks trying all sorts of renovating materials including Facllasa with a slow heavy polisher but have been unable to get an even colour across the hull.

The original orangy red gelcoat had faded and over the years the strops have battered the hull even although the hull has never been in the water. Also I have found many pinholes through the gelcoat. The white gelcoat is fine and will stay as is.

Can't really blame the poor old hull. It was moulded sometime around 1978. Red is a very poor colour for fading.

The colour will be Bermudian blue.

It has now had three coats of undercoat, the last one with 60% topcoat.

This is a photo of how it is now.

I will post pictures of the finished job (if it turns out ok)

Looks good. Have you been building it since 1978?

 

[Strathglass]

Glad to say no,

But have gone through - redundancy, divorce and remarrage since I started working on her.

Things have only got done when I had the time and resources available.

I moved her into the garden two years ago and since then
over 50% of my time has been spent on her.

I am looking at the same job on my old Halberdier ( 1971 ) ( Except that she has been painted before so I have the joy of removing all the old ..failing..paint).

Are you using single or 2 pot paint?? Are you spraying, and if so do you work from inside a 'habitat' or just wait for the right sort of day??

Regards Nick

Hi Nick

Using two part paint.

Degreased and washed hull fully.
Sanded hull with 240 grade (Random orbit sander)
Washed and dried
Filled visable marks with International watertite.
Sanded and washed again.

First undercoat was 90% International polyurethene undercoat + 10% final colour + thinners + accelerator. Sprayed
Then had to fill about 100 small visable masks (many pinholes)
Washed and dried again.

Second undercoat was 80% int undercoat + 20% final colour + thinners + accelerator.
Filled more blemishes.
Sanded with 320 grade wet and dry (wet)

Third undercoat was 40% int undercoat + 60% final colour
Sanded with 400 wet and dry (wet)

First topcoat International polyurethene Mauritius blue + thiners + accelerator.

Very light denibing with 800 wet and dry (wet)

Mixed up the final coat with all the necessary ingrediants poured it into the spraygun and was about to put the spraygun together when it sudenly turned from a bright windless sunny day to a miserable cloudburst.

<span style="color:blue"> I had to discard a full litre of premixed paint. At least it was not on the hull when the weather changed and the gun itself was still clean </span>

When the weather turned nice again. I had to fully clean the hull again before applying the final coat.

It went on very well.

I did spray all the paint on.

I was working outside without cover.

Fortunately I had seen the forecast for a spell of very good weather and decided the timing was right to take the plunge. I already had all the materials to hand.

The temperature was above 20 degrees all the time I was spraying.

The total task took about a week, but I have sprayed quite a few boats in the past and have the necessary hardware.

<span style="color:red"> Most important being an air fed face mask </span>

I use two compressors one for the gun and one for the mask. This way I can be sure that the paint fumes do not enter the air supply to the mask.
I use a 1.2 nozel in the gun which is dedicated for two part polyurethene spraying only.

The materials I used were.

Undercoat - International Perfection undercoat.
Topcoat - International 900 series two part polyuretyene Maritius Blue (perfection could be used)
Thinners - International YTA810 (No 10 thinners) This evaporates quicker than the brushing thinners.
Accelerator - Interspray 800 accelerator ( Speeds up drying process in colder conditions)

I hope that answers all your questions Nick.
Any more just fire away.

I don't envy your task of removing all the old paint.

My next job is to put on the anti osmosis epoxy and paint the lead keel before antifouling

Cheers

Iain

Thanks for that Ian.I have saved that for the 'day'...looks very smart, well done.

BTW I think I might use Farrow system to get the old paint off !
