I have a an old teak swim platform (boat is 1988) that I have tried to bring back to life. I have used teak cleaner, teak brightner, and teak oil but what I am left with a brighter grey wood. What I would like is to get back to the original look of the teak.<br /><br />Any suggestions? Would stain work well?

Re: Refinishing teak

Just finished an 88 Thompson swim platform that was badly weathered, it looks great. I originally tried all the easy stuff but they worked about as good as it seems your try did. I ended up sanding it. Was well worth it. I used a random orbital sander on the surfaces and by hand in-between the slats. You will be surprised on how well the color comes back after sanding and oiling.

Re: Refinishing teak

Jack,<br /><br />The original finish will affect re-finishing.<br />As Sandpaperman suggests the sanding block will always work, but depending on the original finish, and the finish you want to go back with, a chemical strip may be more advantageous or even necessary.<br /><br />The grey you are seeing is most likely UV damage to the surface of the wood that has not been completely removed in your cleaning process, or than has been trapped beneath some unremoved bits of old finish. Either way the next step, before you can re-stain, is to either restrip or sand the project.<br /><br />After you get the wood fully clean, you will want to apply the highest quality oil based stain you can find. I have preferences, but am not sure whether I can name them without violating BBS rules (I'm still a rookie here)<br /><br />Feel free to give me a call if you like. I'm in the Metro Atl and would be glad help.<br /><br />770-318-1032 (mobile)<br /><br />P.S. - Leaving for La. on Mon. am, so won't see any replies here till next week.. <br /><br />Cujo

Re: Refinishing teak

A little confused on the statement of unremoved bits of old finish. I thought teak did not have a finish on it. (By finish I am thinking of varnish or some coating like that.)<br /><br />What kind of finish are you referring to?

Re: Refinishing teak

Jack, I just refinished my teak last month. I used some bleach,( alot of people will say no to that) and a nylon scrub brush all the grey stuff came right off like a thick paste. I dried it with clean rags, let it sit for about 2 days to let it dry, did some lite sanding, and gave it watco teak oil "per directions" of the manufacturer, let that dry, and then gave it 3 more "very light" coats. I mean after the first, I just tipped the brush in the oil, and brushed it on till it all disappeared into the wood, I didnt wipe those coats off. And it all looks beautiful.

Re: Refinishing teak

I scrubbed mine with detergent and a brass brush, scrubbed some more with lemon oil and same brass brush, sanded the fuzz and raised grain off, soaked it in lemon oil for a few days until it wouldn't absorb any more, then coated it thick with paste beeswax (Snoseal, for boots etc). Looks beautiful even after a few seasons, the wax paste is quite oily and soaks into the wood.

Re: Refinishing teak

Jack,<br /><br />It could be true that your teak is unfinished. That is to say that it has never had any type of stain, sealer, etc applied.<br />I just assumed that it had been finished at some time in the past and that you were refinishing the wood.<br />I apologize for the confusion... My Bad...<br /><br />If the wood has been previously finished it will need to be properly cleaned and/or stripped before refinish, but as Mark points out, untreated wood can be cleaned with a mild bleach solution, (no more than 4 parts water to 1 part bleach, unless you are experienced in using bleach on wood) a garden hose, and a stiff nylon brush. <br />The only additional thing I would add is an oxalic acid based brightener bath afterwards in order to neutralize the bleach and its detrimental effects to the wood.

Re: Refinishing teak

Thanks everyone. As I said, I had gone through the clean/brighten/oil treatments and all I had was a cleaner, brighter, more protected (the oil) grey. <br /><br />Does the lemon oil bring out more color than teak oil? Which is better?<br /><br />My thoughts are after 20+ years of not TLC whatever stain or color was in the wood is gone, and that a stain would be a real help here.<br /><br />Any disadvange to the stain? If not, any reccomendations for a good one?

Re: Refinishing teak

I don't think there's any point to staining teak. Just sand off the grey, ultra-violet bleached fibres to expose some fresh wood. Normally it doesn't take very long at all with a random orbit since the greyed wood is so weak. On really bad teak I've even used a very sharp paint scraper to start with. The natural colour of the wood is very appealing, and the teak is loaded with oil anyway.<br />Once you've got it exposed, you need a plan on preservation: perpetual oiling, spar varnish, or Cetol type products. I think you can rule out the spar varnish given it's location and function. Cetol is a possibility, but it changes the teak tone & colour quite a bit. Oiling is a huge amount of work since you need to re-apply frequently or you're back to square one. But that's probably the most sucessful plan.<br /><br />Some people simply live with the silver colour or even learn to like it! :)

Re: Refinishing teak

Jack, I snagged this from a diff boating forum a long time ago. Maybe it is helpful?!?<br /><br />Regarding teak care and maintenance, here is what I do. For 15 years now I have used the Amazon brand of teak care products. I have tried many others, and keep coming back to Amazon. Do not confuse teak OIL products, such as Amazon, with teak SEALER products, which are a mix of oil and cheap varnish. The sealer type of products will last longer because of the varnish/resin content, but they have a slick looking surface, yellowed, appearance. Use of the Amazon products is a three step process - one-step cleaner, a prep product to eliminate moisture, and the teak oil. <br /><br />I only use the one-step cleaner, as the two step is too harsh on the wood and the soft grain. I have tried other brands, but Amazon's is the best! Put the cleaner in a spray bottle, and spray on the wetted wood, let sit for a few minutes, and scrub with a plastic handled non-abrasive PAD. These can be found in boat stores. A tooth brush is good for tight, hard to reach spaces such as the louvered doors. But don't use scrub brushes. They take too much of the soft grain out of the teak and leave you with a raised grain surface that will become increasingly hard to maintain. Then rinse with a hose, and re-apply the cleaner, scrub pad, etc. You will have to do 3 or four applications, and you can tell when the wood is getting clean becasue it will turn a darker, richer color on each application. When you're only rinsing off clean foam, you know the dirt and old oil residue is gone. Then I use one of those foam cored sanding blocks, and lightly wet sand the surfaces before the wood dries, to smooth out the grain and get rid of any cleaner residue. Unfortunately, any teak cleaner exposes the harder grain, and some sanding is necessary.<br /><br />If there is still black (soft) grain showing, the wood is not cleaned deep enough, and you will have to continue to sand down to it. When the wood is thoroughly dry, it will look like new sanded teak. Now, at this point, if the teak is several years old, and has never really been restored, you should ORBITAL power sand to cut through the raised grain and bring back a factory new surface. The hand sanding block simply cannot restore a weathered surface. I do this about once every four or five years, and it basically gives you brand new teak ready for oiling. (or varnishing). Next, follow Amazon's directions, and apply the intermediate teak prep product. Then I use their top-of-the-line teak oil, called "Blend 55" (sometimes hard to find and requires a special order) and rub on four coats of oil, per instructions. Every month or so, an additional coat of oil keeps things looking great. Many people have commented on the teak on my Whalers, and this is how I do it. <br /><br />Regarding durability, if your boat is stored inside, and used in fresh water, the teak should look great for about 2 years using this method. However, if the boat is under a cover, but outside, and used in sub-tropical sun and saltwater, you may have to re-clean and oil in four months!

Re: Refinishing teak

I restored a 77 cruisers 4 years ago. Plenty of teak that had been neglected for years. The swim platform in particular was nasty, gray, and as rough as old, weathered barn siding.<br />Used a belt sander (100 grit, with the grain) and finished it with a product called Teak Guard. Looks great and holds up well. also, if it does wear thin in high traffic areas, you can touch it up without sanding - blends in great with the old, and dries in about 10 minutes in the sun. The interior teak still looks great after 4 years although I did re-finish 2 of the 4 teak panels on the deck.<br />BTW, am currently restoring a 87 Searay - lotsa fun...

Re: Refinishing teak

I'll tell you what works extremely well... OXICLEAN!<br /><br />No Joke! It may take a few applications on weathered teak, but it really does an excellent job drawing out the old crap and brightening up the wood. <br /><br />Another tip I got from this board... WATCO TEAK OIL, bought at Home Depot, for a fraction of the cost of products at the marine store. Works great so far!

Re: Refinishing teak

I use my pressure washer (1750 psi) to blow all the black/grey crud off. This is a lot easier than sanding & chemicals. Some will say that it blows soft parts of the wood out leaving ridges. That has not been the case for the teak on my 17 year old 23'er.

Re: Refinishing teak

Just started with some small trim pieces. Used a cleaner made by Starbrite (which seemed to work well) and a small brush.<br /><br />I followed this up with a light sanding then applied teak oil and was really suprised at how well the color came back.<br /><br />I may try the other ideas for the larger pieces of wood. The oxiclean sounds interesting.<br /><br />One thing I discovered is that you really need to make sure the wood is good and dry before you oil. I had an area that developed some white spots that I think were due to some moisture remaining in the wood.<br /><br />Thanks everyone. I will try to take some before and after pictures of the results.

Re: Refinishing teak

Jack you are absolutely correct about making sure the wood is dry before applying the oil. In the hot sun, 24 hours is usually enough. Otherwise, it may take 2-3 days.<br /><br />The OXICLEAN will not damage the wood fibers like bleach can. I won't kill out your grass either, should you be cleaning near it. Per ounce, it's alot cheaper than the "marine" teak cleaning products.

Re: Refinishing teak

Thanks to everyone for their help. Just thought I would post what I have found out.<br /><br />1. Teak will come back to life in spite of what it looks like when you start.<br /><br />2. Get all the wood off the boat. In some cases where the nuts/bolts had rusted like crazy this was much easier said than done. (Everything went back on with new stainless hardware)<br /><br />3. Clean and then clean again. I started with dishwashing liquid and a scrub brush. Then tried various cleaners such as Oxyclean, laundry detergent, and the commercial cleaners. <br />I found the commercial cleaners seemed best, but only marginally. I ended up cleaning with the common materials first, then a final with the commercial teak cleaners.<br /><br />4. On some of the difficult pieces I used the commercial teak brightner. I also found that bleach did a good job, but I needed to use the bleach then rinse very well to keep the wood from being damaged. I never saw damage, but I wanted to be overly careful.<br /><br />5. Sand the wood with a palm sander and 120 grit paper.<br /><br />6. Let the wood dry. This is the most deceptive part of the process. I found it too easy to think it was dry and move to oiling only to have the white spots appear in a few days/weeks.<br />I decided to give it more time than KaGee reccomended. 2-3 days just did not seem to do it for me. Could have been humidity, but I found that 1 week seemsed to work well. On small pieces I put it in the oven at 130 degrees for a few hours to make sure.<br />With all the work it took to get this far a few extra days were well worth it.<br /><br />7. Oil, but don't go overboard, I found that it was easy to put one coat too many and end up with surface oil that dirt sticks to.<br /><br />Thanks everyone for the help. Hope these ramblings help the next person.

Re: Refinishing teak

I recently restored some teak that hadn't been touched in about 10 years with light sanding and Teaqua. Not sure if anyone else has tried it but I am interested to see how it holds up this season.

Re: Refinishing teak

This is just a sample...actually...this was one of the nicer peices on my boat...the full teak swim platform and the trim on topside of the cuddy are grey every year...takes cleaning, sanding, cleaning again...brightning..then lots of teak oil to get these results...I have to do it every year though..<br /><br />

Re: Refinishing teak

JustMrWill,<br /><br />Love the picture. I think mine was worse. I don't think anyone had prepped the wood in 16 years.<br /><br />After you clean how long do you wait before oiling?
