Glue
I am finishing up my first table. I made the top by gluing together
several pieces of wood. I made the legs out of 1X2 glue together to make a right angle. One piece of the leg was ripped so the total leg was the same length on both sides. The legs were together with 1X3. Now the table is nearing completing, I have a concern. I have attached the top to the leg assembly with cleats dadoed in to the sides of the leg assembly (1X3) The cleats securely hold the top to the legs, but I would like to glue the cleats into the dado. Alse since this will spend some of its time outside I would like to seal all surfaces of the table by varnishing it before completion. Will titebond or any glue make a satisfactory joint with a varnished surface? |

@speranza.aioe.org: Will titebond or any glue make a satisfactory joint with a varnished surface? Typically, no - the glue may stick well to the varnish, but then the varnish will pull off the wood. Typically what's done in cases like this is to tape over the area that will be glued, then varnish (or whatever), remove the tape, and glue up the joint. If it's going outside, you'd want to use Titebond III or epoxy. Also, you'd probably want to use spar varnish. Spar varnish is softer than regular varnish, and tolerates thermal expansion due to sunlight better. John |

John Your best bet is to epoxy coat all parts before assembly, use epoxy for the glueup then varnish after assembly with a GOOD brand of marine varnish (i.e one sold in chandlrys not DIY stores). Even so, most boat owners revarnish brightwork every year or two, unless they have fitted covers for it to prevent UV damage, so dont expect your table to be maintenance free. Dont stand it on grass or bare earth and add plastic feet on the bottom of the legs so they aren't in direct contact with the ground, or you will be stripping and refinishing the legs long before the rest of the table. -- Ian Malcolm.

OP Thanks for the comments. The outdoor stone-patio use would be occasionally during the summer. It would spend a lot of time on a wooden floored covered porch. The rest of its time would be in my wife's studio. I planned on putting some sort of button feet on the legs so they are not in contact with the ground. |

I planned on putting some sort of button feet on the legs so they are not in contact with the ground. I assume the porch has one side open to the elements? If so, its going to be subject to significant humidity and temperature changes that make epoxy sealing the best option for long term stability, especially if you haven't allowed for wood expansion/contraction due to varying humidity in your design. If not its effectively indoors so dont worry about it apart from a table cloth to keep the sun off it in the porch, as indoor finishes and glues are fine for occasional outdoor use in fair weather as long as you never leave it out if there is any risk of rain or dew. -- Ian Malcolm.

Will titebond or any glue make a satisfactory joint with a varnished surface? -------------------------------------------------------------- Let the cleats float in the dado. Do NOT use spar varnish, this table is not a spar. Do use epoxy. I'd use a slow hardener so you get about 30 minute pot life at 77F. Jamestown Distributors and System 3 are good sources for epoxy. Assemble everything then apply a marine coating. Epoxy requires UV protection, plan accordingly. My choice would be Epifanes marine coatings available from Jamestown Distributors. SFWIW, Jamestown Distributors is in Rhode Island and I'm in LA which puts them about 3,000 miles from me so I just drool when I look at their web site. They have good engineering data. As far as button feet are concerned, make your own. Get some 1/2" PVC sheet. I had access to a lathe to make mine, but a band saw or even a disc sander will allow you to make round buttons 1/2" thick from sheet stock. C'Bore each button to accept a pan head screw recessed into button. 17/64" dia thru hole in plastic, 3/16" pilot drill in the wood to attach button to wood. Use stainless #14 x 1" coarse thread self tapping pan head screws. Better figure refinishing every 3-4 years along the coast of the Carolinas. More frequently as you go south. You might get 2 years in Miami Beach. Have fun. Lew |

You're contradicting yourself. Epifanes is spar varnish. So is Pettit Z-Spar (my preference) or Interlux. Now, if you mean "do NOT use MinWax brand spar varnish" (or any other brand sold at Home Depot), that I could agree with. The label notwithstanding, I don't consider MinWax to be a true spar varnish. (btw, beware that Epifanes, et al, also make interior varnishes which are not spar varnishes, and are not intended for exterior use...read the labels). John |

: A few years back Practical Sailing did a test of 54 finishes. After two years the coating integrity of Epifanes, Helmsman, and Z-Spar Captain were Fair-, Fair, and Fair+ respectively. There was no single-component product in the test that got better than "Fair+". Now, you may think it's worthwhile driving across town and spending twice the price to get a product that is "Fair-" but I think I'd go with the cheap stuff. I wonder if they tested any Home Depot grade products, or if the comparison was strictly on marine finishes. In my experience the Petit is markedly superior to Minwax, altho it's not a head-to-head comparison since the little boat sits out in the weather, and the Minwax coated stuff is sheltered on the patio.

John Is that the same Petit that I knew when I was a kid. They made great model airplane dopes, and glues. I thought they went out of business. I don't see them around NJ, NY or PA -- Jeff |

I don't see them around NJ, NY or PA Don't think so - I typo'd the name, should have 3 "t"s: Pettit. I don't think they've ever done anything other than boat paints and varnishes. John |

: In article , says... I wonder if they tested any Home Depot grade products, or if the comparison was strictly on marine finishes. "Helmsman" is the "home depot grade product" that was under discussion earlier. Ah, missed that. A little surprised by that result. In my experience the Petit is markedly superior to Minwax, altho it's not a head-to-head comparison since the little boat sits out in the weather, and the Minwax coated stuff is sheltered on the patio. Have you ever tried them side by side on the same surface with the same prep? No - based on my experiece with the Minwax in a (somewhat) sheltered location, I have no reason to think it will perform better in any other location. John |
