He believes that sanding leaves a sharp top edg= e on the pore which leads to the problem described below. Using steel wool b= reakes the edge of the pore allowing the finish to flow into the pore. Of co= urse, he's not using water base so he can do that. Is anyone just filling with finish out there? </BLOCKQUOTE>-- Richard Anderson Anderson Piano Service mailto:tknostf@foxvalley.net http://users.FoxValley.net/~tknostf/ <BLOCKQUOTE> From: Jon Page <jonpage@mediaone.net> Reply-To: pianotech@ptg.org Date: Sat, 12 Feb 2000 14:35:31 -0500 To: pianotech@ptg.org Subject: Re: Pianolac vs Enduro or ? </BLOCKQUOTE> <BLOCKQUOTE> PianoLac, The Sealer has components which fill the pores. Arthur has the proper terminology for their function. One of them is a super wetting agent which loosens the tension within the m= aterial. You have noticed that as you spray an open pore finish, the more coats you = put on, the bigger the pores get. This is caused by the tension within the material= (sort of like a meniscus). The wetting agent allows the material to flow deeper into= the pores drawing it in; where before it developed surface tension at the edge of the= pore. Jokingly I said the molecules have a tendency to lock arms and prevent each= other from falling into the precipice but the wetting agent has them acting like = lemmings. </BLOCKQUOTE> </BODY> </HTML>
