Teak Refinishing
1.) If 150 grit paper will work , use it, but i wouldnt go coarser than 120, nor finer than 150.2.) I wouldnt worry about color matching for several reasons; a.) If the teak has been sanded down to bare wood plus a hair, the final color will be about the same as the wood itself dictates ( more or less ) without too much regard to age. b.) Carefully observe all the wooden furniture in your home and you will notice that the individual boards that make up a side panel or table top NEVER really match in color. As a matter of fact, if you go to a quality lumber yard and look at the really fancy expensive imported woods, one end of a board rarely matches the other.It is the slight mismatch in color AND grain that gives wood that unique look. c.) To the non believers... try this experiment: bleach one half of a board and leave the other half unbleached. When dry and ready, apply any "clear finish" and you will notice that you DONT notice a difference. This is because all clear finishes have a slight ambering affect and will re-amber (if there is such a word) the wood. The only time you will see a difference with bleach is if the finish is classisified " water white " which i have never see in any non comm'l stores. And since water white finish leaves wood looking very lifeless, you will apply water white first then a tinted color finish on top . Will look like s**t if you dont know what you are doing. d.) Most importanty, like most natural substances, wood ALWAYS matches wood. That is , if you have a room or boat full of wooden furniture or things, you can have oak, walnut,mahogany, teak etc. and they will all go together just great. It is not like matching colors in paint or fabric.3.) If you can spray, more power to you.Finish goes on better and faster. Fot thr interior panels and bulkheads, any middle grade varnish or eurethane will last for many years. I always opt for the eurethanes because they are much tougher. Be sure that what ever you use it is a marine grade. Not just for UV protection but also for chemical resistance. As for the parts you removed, i would assume they are the grab rails, table and counter edges, fidle rails etc. you might want to consider a more bullet proof finish. The auto industry has always been light years ahead of any other industry when it comes to finishes. Go to an quality auto paint store and get a 2 part clear euretane finish for auto's. It will also work great on wood...TRUST ME ON THIS ONE. you will be very impressed with results. Only need 3 thin coats and wood will look like it is under an inch of glass and will NOT look like plastic. Ever notice the finish on expensive new power boats? especially the wheel and accesories.4.) Whenever working with teak or any naturally oily woods, ALWAYS wash area down with LAQUER thinner ( not paint thinner ) prior to painting or glueing.This will remove a small amount of the oil from the surface and give you better adhesion.5.) thanks for the opportunity to let me grandstand. I used to build very expensive custom furniture with exotic woods and have some experience in this area.
