I am about to revarnish light coloured ply decks after taking back to bare wood. Approach at this point is as follows: |
2xSP320 |
Any one speak Italian??!! |
I have just used 3 coats eposeal, 2 of epoxy and 3 of Ultrovar. Looks good. Marineware are very helpful for supply as is Martin at SP Systems. |
Thx for replys so far. |
I think the Eposeal gives a really good seal and base to the subsequent coats. The advantage of going with one system is that you know everything is compatible. One important thing is that you must wait at least 10 days between the Eposeal coat and the SP320 to allow the solvent to come right out as it might bubble up. |
Thanks Garry, |
Trick is to overcoat within the curing period and then you don't have to sand between coats of the same layer. If it does cure then I used 120grit to get a good key. I used this between the sealer and epoxy and then between epoxy and Ultrovar. It seems to be important to use the thiiners of the next coat to wipe down between the different coatings as a de-greaser ie. use the epoxy solvent before epoxy and the Ultrovar solvent before the Ultrovar finishes. Between the Ukltrovar coats I allowed a good cure and rubbed down with wet and dry with a bit of Fairy Liquid. Make sure you have got rid of all slake and bits. Work dust free as possible. A couple of important tips. A) DON'T work late in the evening or if rain is imminent - it will turn horribly milky and you'll have to start again. B) DON'T mix more than you can use in 20 mins as it will start to turn jellylike and the finish will be poor. Make sure that you cover all the surface and skim as you go - if you try to go back and "just tidy it up" it doesn't work!!! C) Use a foam roller to apply and skim off with a light touch of a jennybrush (it removes the orange-peel effect) and gives a great shine. You can get the rollers and the brushes cheap on ebay. Chuck them after use. If you want to contact me off forum use the email. |

I find that a bottle of beer in my left hand whilst rubbing down the boat with the right really helps my balance. |
I did the decks of my smokers this year from bare wood, colron stain & 11 coats Intenational Schooner, 9 with the foam brushes and the last 2 gravity feed spray gun exellent value start to finish 6 days 2 coats a day. |
you've found a spray system that takes marine varnish? |
Hi Mags is is a Prof grade automotive gravity fed gun about £47 + vat can buy a selection of needles and nozels but I find the 1.8 mm ideal for all marine grade paints and varnish, I painted the hull and topsides of my speed boat with Blakes 1 pack, got a great finish and very durable 2 season use already. |
Hmm, not too expensive really, considering the finish you can get. |
SP LEAVES A RESIDUE .Unless you only use SP you will have problems with reaction if other systems are mixed when applying.Two pot does not let the wood breath . Single pot !If you want a really hi gloss, add a smidge of meths and stir into the single pot varnish. |
If it was looked after I would send it for the cost of postatge + a small fee for wear and tear!! |
