I have just finished planking the deck of my Missouri, and going to the paint shelf, found I had run out of mat varnish, but I did have a tub of Sadolin extra, which is a exterior joinery finish, now this is a serious exterious finish, as it says on the tin, Extremely Water Resistant, has any one tried this as a planking finish, it sounds just the bees knees for decking, any thoughts ?

Used a lot of it in the building industry,

You might find it a bit thick when you put it on.
You might find that it fills all the gaps and you end up with the same sort of finish you would have got if you used ply { all flat ,all one colour}

As for being waterproof you will have no problem there. It lasts for years outside.

I suggest you try some on some of your waste timber and see what you think. ???

Bear in mind the more coats you apply the darker the colour will be. :-\

Hi

I once used a 2-part clear finish which was made by Sadolin , and specified for bar tops and dance floors
where an extremely hard and waterproof finish was required.  It wasn't cheap and I had to buy 5 litres
(from Brewers at about £15 if I remember correctly).

I used it on the sanded veneer surface of a period coffee table, and whilst in drying the surface has to be kept on a perfectly flat / horizontal plane, it could have been applied with a tooth brush - the result was phenominal with a satin finish as smooth as glass, and not a brush mark in sight.

I used 2 pack epoxy, stuff used for laying up fine fibre on model plane wings. The finish is very smooth and the shine very deep as well as adding strength and waterproofing.

i second the two part epoxy use the slow setting stuff 3hr is good gives you 45 mins working time ,sets hard it will water proof and strengthen and if you use a credit card or similar the finnish will be smooth as glass.the more coats you add the smoother it will get.
