With the recent heavy rain I have found a few drips inside which I have traced to deck fittings and the towing ring on the bow.
What should be a straightforward job,on removing carpet and shelving,I found some previous owner had fibreglassed the back of all the fittings,doh!!!
Anyway,my question is,does anyone know the make of mastic to use?
When I replaced my windows,the mastic sealing the frame to the cabin was grey coloured and had the consistency of putty.
When I replaced my window frames,I used guttering mastic,but because of the smaller grip area of the deck fittings,I think the stuff that originally sealed the window frames would be better.
I have now got to cut away the matting behind the fittings to get at the nuts.
Many thanks!!! some previous owner!!!
Any advice about the mastic to use gratefully received. |

Butyl tape as used on caravans, commercial roof sealing, glazing etc is ideally suited for marine use too. You can buy it from e-bay https://www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p2380057.m570.l1311.R11.TR12.TRC2.A0.H5.Xbutyl+tape.TRS0&_nkw=butyl+bedding+mastic&_sacat=0
What they call tape is a strip of the sticky rubbery mastic with a waxed paper protection on it - cut with scissors, peel off the paper, you can actually mould it if you need a bead rather than a 4mm thick flat strip. Comes in black, grey or white. Stick it down, put the fitting on top, push through the bolts, bolt up and later trim off the excess with a sharp craft knife and keep to mould for the next fitting.
Finally living the dream!

Many thzanks Fred and Cliveshep for the info.
Been to the boat today to decide how I am going to tackle this job and on trying to remove the shelf under the side windows I found that not only had the inside of the front fittings been glassed over but the bottom of the shelf has been glassed to the hull.
This glassing over the inside of the fittings has obviously been a quick bodge for leaks which has worked for a time untill water has percolated through the matting.
I will sort it in the fullness of time, but I have often thought that buying a boat is rather like taking up with a new woman,in that you don't really know what you have got untill you have lived with them for a year!9 |
