    Dear All,

    Having got a bit more time on my hands now I have started to look at the wood in the cabins.

    I have had some great results restoring water stained veneer panels using Owatrol/Netrol
    Marine Strip Paint, Varnish & Antifoul Stripper and then Net-Trol Wood Cleaner & Colour Restorer. These are both water based and I have found very effective on the varnishes used by Nauticat. I’ve used Epiphanes rapid clear varnish once I’ve stripped and then restored each panel. I’ve found sanding to cause too much stress, but a stiff wire brush sparingly applied can be effective.

    However, I’ve now got a large number of panels that look like the attachment below.

    What would people best advise on how to sort out this problem ?

    rgds,

    Richard

    1- Owatrol/Netrol
    Good to know you had success. I had some difficulties coping with water strains (condensation) on veneered wood. I tried oxalic acide with no success. Sanding hardly restore the original colour and each sheed of wood are so thin … I’ll follow your track.
    2- restoring discoloration
    I’ll give a try to Net-Trol Wood Cleaner & Colour Restorer
    3- varnishing inside
    After some sanding veneered wood inside (400 emery wet paper is more than enough) but leaving some old varnish (eg, not to bare wood) I apply International schooner or schooner gold with 30 to 50% international matting additive. Still, under some light conditions (sun lignting parallel to the surface) the result appears very slightly dull. I have been advised to try some light “steel whool”. Alternatively I’ll try some 1000 or 3000 emery wet paper. I’ll let you know.
    Varnishing massive wood is no problem : very light layers and some light sanding (400, wet)
    4- difference in colour on picture 20161004_135719.jpg
    I refer to the change in colour on the solid (eg not veneered) wood at up and left angle of left window. I faced that change in coloration when revarnishing wooden frame of dinette table in the helm house. I feel the difference is due to a difference in absorption of varnish by the wood, I think old varnish remains prevent absorbtion and yeld lignter colour. I’ll have to redo the varnish after deep sanding to homogenise the absorbtion which is no problem with solid/massive wood.
    Wood framing(massive) of the staircase to the galley has the same symptom. I’ll do some deep sanding and wait for monthes before varnishing, to dry out. I’ll keep you informed.
    I also suffer from dark dots or stains here and there, especially on outside veneers covered with Cetol. Probably some fungus déveloped where water penetrated. Found no solution, oxalic acide not being satisfactory. Was advised by old sailors to extensively sand to remove dark parts, which is not a solution with veneered wood.

    Most of the condensation under the windows and rubber frames stopped appearing since I keep here permanently under tarpaulin in winter. No more condensation.

    I liked your idea of using the Colour restorer on the darker patches. I have had quite a bit of success today. I used a few coats of Netrol stripper, then the colour restorer. The advantage of this is that you get no dust everywhere in the boat from sanding, which I think is a major plus.

    I think I will proceed with this first, then resort to sanding only if I have to. It also means the same approach can be taken for veneer and wood surfaces.

    I bought my nauticat 33 3 years ago. The inside was done with owatrol. By moisture there were many weathered spots. I have the whole inside of the boat with cleaning solvent, light polished and 2 times painted with Sikkens Cetol tgl satin plus, color teak (085 int. Woodcolours) Almost all places are nice now. Drying after the first lay took a long time.
