Jul 16, 2002 · In my opinion the adhesive is overkill for the ceiling. And I don't like to rely on finish nails for this application. My own preference is to use 1/4" crown staples- for the 3/8" ply I would use 1 1/4" or 1 1/2" long staples.

Apr 12, 2009 · Bill,Actually the ceiling will be for the lower level of a two-story building that's 65+ years old. The joists are 4*6s on 16" centers. I am planning on insulating between the joists and using the plywood to keep the critters out. Edited 4/12/2009 8:42 pm ET by smllr

This would create a flat surface to adhere and nail on the double tall 2x6 joist. It would also add some stregth too if you glue and nail the plywood filler the entire length of the i-joist. Avoid the temptation to use 2 pieces of plywood filler on each i-joist. This will align each plywood filler joint right in the center of the 16' span.

May 15, 2006 · Working with epoxy is a PITA. (I can say this with some authority, having epoxied together a kit boat.) Not worth it for a plywood ceiling, and not likely to give a smooth finish.If I had to tape it I'd use mesh drywall tape and cover it with either setting compound or (better) a premixed spackle.But some sort of lath over the joints makes much more sense.

Sep 17, 2011 · They are both equal in strength to hold up the plywood. I think nails are better for appearance myself. 2" or 2 1/2" screws or nails are sufficient. Make sure they are weather resistant because moisture will condense on the heads. I'd …

Dec 8, 2003 · What would the nailing pattern be for a 4×8 sheet of 4ply plywood on an exterior stud wall (2×4) along the edges and in the field? What size nail do you use a 6d or an 8d? Now what if you want to use screws, such as those Deck Mate square drive, what whould the nailing pattern be for the same situation along the edges and in the field?

The Anatomy of a Box Beam. Most box beams are made of pine or poplar and 2x framing material. But those materials can be expensive and labor-intensive to work. poor dimensional stability is another limitation. use cabinet-grade plywood for blocking and MDF for the finished surface instead; both are relatively inexpensive and stable. structural beams also can be …

Oct 1, 2003 · Glue the supports to the ceiling. After carefully snapping layout lines, I install the supports directly to the ceiling drywall with liberal amounts of heavy-duty construction adhesive. (For stain-grade ceilings, I glue finished plywood to the ceiling sections before the crown molding is …

Jan 25, 2003 · Don't use plywood because as what's his name said, it'll warp/ twist. Instead use MDF. If you like the wood look, use MDF with a birch veneer - available in 1/4" and 1/2" thicknesses. Regardless, this wood route is going to give you a hard/ bright/ reflective sound surface. Noises will be amplified. You may find that undesirable.

Tack the ceiling panels in place. Plywood panels cover imperfections in the ceiling, create a smooth surface for paint, and offer a nailer for trim. If the layout and framing was done well, the panels will all be very close in size, if not exactly the same. Take care to locate lights and registers and cut the panels accurately.
