i'm working on my indoor staircase. the plan is to assemble red oak into individual treads,and finsih them in the garage where the mess can be held to a minumin. once a few finish coats are on and hardened, they will be fitted,glued and nailed down onto the existing treads. the new treads are made of of manufactured 3/4" tounge & groove "strip" planking. and a few edge peices that i'm making in my shop.for these shop produced peices i had to make the tounge n grooves with onhand tools -so the mateing surfaces aren't quite ideal. does anyone know of an off the shelf construction glue ( idealy caulk gun dispenced- & bounus points if it can be bought at a homedepo) that will fill gaps under 1/16" AND dry over night? to the point where it can be taken out of the jig and worked on? my self imposed schedual is to glue up one a day, in a jig/mold.
 
Either Liquid Nails or the PL line (PL 200, 400, etc.) are fine products, and available at Home Depot. Just read the labels to see what each flavor does best, but wood is pretty easy to glue. Any wood glue (Tightbond, etc.) will bond overnight as well, and is easier to work with, but may not fill the gaps the way you want. It will hold very well though, even with voids. Personally, I'd use wood glue and fill gaps with filler or a sawdust/glue mix if necessary.

I would use the PL Polyurethane based construction adhesive (don't remember the number but the label is yellow and black)
One thing to remember about the polyurethane based is that it will expand while drying, I mention it because it's important to have the pcs. clamped over securly fastened during the drying process. if it should happen to squeeze out during curing, it can be trimmed with a razor blade once dry. It WILL NOT accept a stain, so neatness will be a plus.

A few advantages with this product over wood glues, especially with stairs, is that it won't dry out and crack with age, (as with say Titebond or Elmers) and will remain a little flexible. Once set I feel it's as strong or stronger than a yellow wood glue.

Good luck, Pat
 
I am not a big fan of Liquid Nails - PL, GE, or LocTite products are much better IMO.

I am not that experienced with finish materials but I would suggest a polyurethane product and maybe even the gorrila or loctite brand poly glues?

Good luck!
 
I have used for years Elmers wood glue,light or dark, never a call bck in over 26 years. Mike
 
thanx pat n pooh...i tryed a few sugested approches, an ended up with pl pollyurethan. it's propably the easyest to use and sets up in about 12hours( in a well heated garage). when i can remove from the glueing jig and trasfer to my dinning room table, where it continues to set up. thanks for all the replies
