Any joint that can 'work' butts, scarfs will break integrity and
promote loss of adhesion.... no matter if varnish, acrylics, and the ever popular orange boat paint. Honey Teak, etc. will be fairly dark when you first apply, but will fade over a short time to an amber glow - similar to oil based varnishes. If the teak darkens too much, you can bleach with oxalic, etc. to lighten before large scale applications and with apparently no adhesion problems later on. I have acres of Burmese teak and 'everything' that I put on will darken; therefore, I bleach it first with oxalic. I also before *any* coating cover with saran and let the sun 'develop' the color and hue for several days/weeks before bleaching and coating. Additional comments with Honey Teak, varnish, etc. .... I usually do a hand-rub finish step to develop the irridescent 'patina' of the wood. This is essentially a frictional heat process done by a bare hand that deveops the 'warmth' effect in high quality varnish, etc. Plus, a hand rub will provide a totally flattened surface onto which further coats are easily laid down. .... Hand rubbing is usually only found on mega-yachts with unlimited budgets, Hinckleys at boat shows, museums, etc. If you only slap on successive coats and dont hand rub, all you get is coated wood; if however, you also hand rub then you get perfection that 'glows. |

Do you rub with an abrasive polishing compound like pumice or rottenstone? |

First flat sand with 1300 or 2000 grit wet and dry to get a FLAT
surface; then, .... Rottenstone and water for gloss, rottenstone and oil for semi-gloss, pumice and and oil for satin. For a 'perfection' surface final coat with an airbrush. The modern acrylic/urethanes can be power buffed (with super fine diotomaceous earth etc. as the 'grit') to make this whole hand-rub process very fast. If you ever have the opportunity to look at the wood trim in top of the line type of private jets or mega yachts or even automobiles.... all the finishes are hand rubbed to a super brilliant surface. A benefit of a flat hand-rubbed surface is longevity. The only finish that is more brilliant than a hand rub on varnish is a 'french-polish' using alcohol and shellac .... but that is NOT for any wet locations. |
