Hi Simon and thanks for the opinion and input.
Strange and interesting as I’m a fan of both Rubbol + and Coverstain!!! … and in fairness had nothing but good experiences with both to date.
But I have the luxury as mentioned in an earlier post of having the time to prep in minute detail … the properties concerned being our own or close relatives or kids.
I used Coverstain to do our exterior maybe 4-5 years back. It was a 1920’s place in trad Home Counties bow windows style. Wood was rock solid, paint was also solid (probably lead based) but rough.
I sanded back to flat wood and Coverstained, Kodrined and sanded and reapplied and sanded and reapplied etc etc … then XD’d x 2 in white underside and black front facing timbers with light sand in-between. And bar a problem area on the front elevation Oak timbers it’s still “nearly” rock solid and suffered almost no yellowing or breakage to date.
The problematic Oak timbers I think I filled with some cheap rubbish years gone by. This next year think I need grind it out with a wire wheel and build up with something decent. … que for another post and question!!!
But both have served well. That said have never used on a wood surface not kodrined in it’s entirety. RIP Kodrin … my first tin of Toupret just purchased
I liked the application smoothness of the Coverstain. I have a can of Owatrol but not yet used it. Maybe time to give that a shot and form a valid comparison. I heard good things from the guys on TP about that.
But as you say, Rubbol is a super primer as well.
From my chair it’s fun to try the differing options. Again I guess if you doing it commercially you might form a quicker and stronger opinion
