A good grade of Varnish, (boat builders use), and/or the \"Ready Fix\" product, (both about P1,000± per gal), works for us as a stain blocker here in the Philippines.
Forget the varnish that come in the pint size booze glass bottle, AVAILABLE EVERYWHERE.........JUNK!!!
BTW, buy ready made bamboo stuff, that\'s what it\'s coated with..........the CHEAP STUFF and one coat!! Do yourself a favor and re-coat over with some good stuff and it will last longer!

Ive tried to find a decent stain block many times but to no avail.. In the UK we use gloss paint which is cheap and blocks everything..Here most stains goes right through local gloss paints and varnish..
The paint trade here is 50 years behind and many paint products are basically useless..
My opinion as a Brit decorator.
We used some used oil on the timbers that our ceiling is connected too..The oil has penetrated the plywood and nothing so far has blocked it..I must have tried every brand of varnish available in the P.I!!
Im glad I did now as at least I have discovered Hudson polyurethane two part varnish.. This is the best decorative product that I have found in the Philippines period..Gives a glass finish that is hard wearing and does not easily scratch..Its really for wood flooring but I am now using the stuff everywhere.
