This answer to this question is obvious, but one of the many things I’ve learnt in life to date is that the obvious isn’t necessarily true, so here goes…

I don’t much like using “neat” finishes – be they oil or varnish, so I always thin them, and apply more coats than specified.
If my tin of varnish says, for example, something like “apply 3 coats for outdoor use”, and I’ve thinned it to 50%, does 6 coats do the same job? Are there any issues I should be aware of in doing this?

this issue is complicated by a lot of things including the viscosity and volatility of solvent added (and that of the neat finish and whatever solvents it might already have added) as well as the type of finish you have (curing – like poly, or non-curing – like shellac).

Your deposition technique also plays a role: do you brush or spray it on? wipe it? do you apply it and then wipe off the excess after a short period?

that said, all those factors are pretty subtle. you’re probably pretty safe :-)

Have your say...
