Summer Sun and Painting the Roof

When we had the boat built we only had a holding coat of paint applied to her by the builders. We were't even sure at the time what colour we wanted the boat to be, so on a whim, and due to location, we plumped for Oxford Blue. We're really happy with the colour, but in the height of summer when the boat is sat in full sun the heat the colour holds is unbearable. During the last heatwave I left a thermometer on the gas locker on the back deck and it read 51.9C. It felt a tad toasty inside the boat too. So, we took the decision to paint the roof a more suitable colour, one that wouldn't soak up the sun's rays so readily. We ventured vaguely into this territory with The Green Man, but the red shade we chose wasn't really very effective. This time we decided to go all out and do it properly.

I sanded out all rust and primed where I had taken the paint back to bare metal. I then meticulously sanded the roof of paint drips from the original blue coat and tried to remove the drips of solder left over from when the boat was constructed. This was a fair old job, and after three hours I wished the boat was 50ft smaller and 10ft narrower. I had a little help, though.
There was a lot more rust spots than I was expecting for such a new boat, and the heatwave kicked in just as work started. The roof became too hot to stand on after 10am.
My friends over at the very lovely Green Boat Services recommended Jotun Marine Paints to us. Jotun have a much larger colour palette than International and are more affordable so we thought we'd give them a go. First we applied an undercoat of Vinyguard 88 primer/tiecoat (I exchanged kitty help for human help).
We're not sure which paint the builders originally used. I'm sure it's in our paperwork somewhere, but because we intend to paint the entire shell again (eventually) we thought a slight variation in the blue that we chose would be okay. We decided that it would be nice to keep an Oxford Blue border and use a lighter colour for the main part of the roof. The Oxford Blue Jotun supplied turned out to be a near perfect match (Jotun Pilot 2 BS381c Oxford Blue 105) and we thought their Silver Grey would compliment it (Jotun Pilot 2 Ral 7001 Silver Grey). The photos of the boat do not do the colours justice so here are the colours from the paint charts.

We painted the blue border first. I think we did two or three coats in the end. Another coat will be applied when we come to paint the sides to tie the sides and roof together, and to hide the silver paint I accidentally splattered onto the handrails!

The Jotun paints used in conjunction with their thinner was easy to apply. On the hottest days we were limited to painting only in the mornings. This caused my two week paint schedule to go completely awry, but with Rob's help we eventually got a couple of coats of silver-grey on too.
 Rain stopped play on a couple of occasions. It was lovely to see the high gloss finish repel the raindrops.

Our lovely high gloss finish was not to last though. It was beautiful to look at, but slippery as hell. Our roof is used a lot for access to the solar panels, the lawn, taking the water hose across, to sit on, and to lie on. I took the hose across in the rain to fill the water tank and it was like trying to traverse an ice rink. We always planned to make it non-slip but was originally going to use sand in conjunction with the paint. A fellow boater mentioned he had problems with his boat roof when the previous owner had used sand. It had cracked and rain had got under the paint coats causing rust patches to bubble up from below. In lieu of his experience and advice we decided to opt for International's Non-Slip Additive. It looks and feels like talcum powder (I don't know whether talc would be a cheaper alternative) and leaves a lovely non-slip surface.

The roof isn't completely finished as I'd like an Aegishjalmur painted onto the sliding hatch (and a Vegvisir on the bow locker), but we're sneaking ever closer to a nicer looking boat.

  1. THE TRUTH VERSUS DOCTRINAL POSITIONS BY STEVE FINNELL

    When the truth opposes doctrinal positions, men reject the truth. If Scripture is contrary to long held denominational teaching most men either reject Scripture outright or explain it away. God's truth, found in the Bible, is the first casualty of denominational rules for faith and practice.

    God's Truth: 1 Corinthians 13:8-13 Love never fails; but if there are gifts of prophecy, they will be done away; it there are tongues, they will cease; if there is knowledge, it will be done away.........13 But now faith, hope, love, abide these three; but the greatest of these is love. (NASB)

    Opposite of God's Truth: Gifts of prophecy have not been done away with. Tongues have not ceased. Knowledge that is God's revelation to men has not been done away with. Faith, hope, love, tongues, prophecy, and special knowledge from God, these six abide with us today.

    God's Truth: Mark 16:16 He who has believed and has been baptized shall be saved; but he who has disbelieved shall be condemned.(NASB)

    Opposite of God's Truth: He who has believed is saved immediately. Water baptism has nothing to do with being saved. Besides that, Mark 16:16 should not be included the Bible away; because it is not included in some manuscripts. You really cannot trust God to give mankind an accurate translation of the Bible.

    God's Truth: Acts 10:25-26 When Peter entered, Cornelius met him, and fell at his feet and worshiped him. 26 But Peter raised him up, saying, "Stand up; I too am just a man."(NASB)

    Opposite of God's Truth: The apostle Peter should have permitted Cornelius to worship him; because the apostle Peter was the first Catholic pope. Cornelius should have kissed Peter's ring and feet. Cornelius was correct, he should have treated Peter with awe, reverence. adoration, and veneration. Peter was the first Holy Father on earth and deserved to be worshipped.

    God's Truth: Revelation 3:1-6 "To the angel of the church in Sardis write:..........5 He who overcomes will thus be clothed in white garments; and I will not erase his name from the book of life....(NASB)

    Opposite of God's Truth: Jesus was not talking to Christians. Christians are once saved always saved, there is no possibility of having their names erased from the book of life.


    The first casualty of God's truth is man's opinion.

    3. Zhoen - I was going to give it a day to make sure Blogger received the complaint. I'm sure it's not the first they've had about him. His comment will be deleted though.

  2. Wow, that's a big, long job. I completely sympathize, as I'm stripping all our door frames and several doors and window frames. Don't have to worry about slipping, though.

    1. This maintenance malarkey seems never ending - just the rest of the boat to go... I'm not a good painter (it makes me grumpy) so I don't think I could cope with stripping doors and windows. That has to be a painstaking job!
