44 ft monohull needs blasting down to epoxy barrier coat. How much would you expect to pay?
Northern England. Just been quoted £2k. Last time I had it done 12 years ago it was £350. I need to find an alternative blastmanDepends on where you would want it done.
I think it could be a lot cheaper in the third world like where I live than in UK south coast
That would have been my guess - maybe a little high. Lot of area to do. Quote for my 33' 4 years ago was £350 for just the keel and same again for the hull.Northern England. Just been quoted £2k. Last time I had it done 12 years ago it was £350. I need to find an alternative blastman
No, none of that. This is Northern England. None of that HSE stuff upp norfI suspect that at least some of the difference is environmental controls. 12 years ago it was less often a problem to create poisonous dust and let it get into the environment. Now I'm sure it not only needs to be fully captured but probably logged and audited as well as a licence to operate. Possibly a couple of extra days and material to create a sealed environment to do the blasting in and £2k would sound about right with some inflation thrown in.

I was quoted £2.5k to do a 31 foot boat last year.Northern England. Just been quoted £2k. Last time I had it done 12 years ago it was £350. I need to find an alternative blastman
We have osmosis on the keel. Lolts of small blisters. It needs blasting to open up those blisters. The boat was osmosis treated some time in its distant past. There is no gelcoat. The hull only has a small number of blisters. None of it is deep blister. The hull needs a different approach to the keel. How deepmthr blasting needs to go will only be know when we take off the coppercoat so we can get some sensible moisture readings. We did a trial area and the reading were not horrendous even though we did the trial on the bit with the worst blistersCrucial to get a blast operator that totally understands how to get the old AF off without damaging the underlying layers.
Yes. Test sample removed it easilyRight. Makes sense. Is removing coppercoat feasible using blasting?
Ok that’s useful infoYes. Test sample removed it easily
I have used 2 blasting contractors and in both cases we discussed the finish required for the treatment/coating planned and they both adjusted the blasting to meet that. Both are very experienced so I guess you have to find a contractor that knows what they are doing. Not difficult down here because of the volume and variety of work they do.We have osmosis on the keel. Lolts of small blisters. It needs blasting to open up those blisters.

Yes, we planned to go back to the gel coat and re-apply Coppercoat but at circa £2k for a 38' mobo plus numerous other maintenance whilst ashore made it too expensive. The operator came down to do a test blast and the results were encouraging.Right. Makes sense. Is removing coppercoat feasible using blasting?
