Okay so I have been looking into my options for underlayment and am in need of further guidance.... (Installing nail down 1/2" strand woven bamboo from Home Legend)
I understand it is recommended to use an APA Rated Sheathing or a Strurd-I-Floor. With that said these are the options that I have found are available to me in my area (@ HD, Lowes and local lumber yards):
@ HD:
1- 3/4" straight edge A/C APA Sheating (in-stock $35/sheet)
2- 23/32 4 ft. x 8 ft. DryPly Sturd-I-Floor (
23/32 4 ft. x 8 ft. DryPly Sturd-I-Floor-439058 at The Home Depot) $34
3- 19/32 in. x 4 ft. x 8 ft. Rated Sheathing Syp (
19/32 in. x 4 ft. x 8 ft. Rated Sheathing Syp-166081 at The Home Depot) $22
4- APA 15/32 A-C Exposure 1 Underlayment Southern White Pine $29
I can special order Georgia-Pacific Sturd-I-Floor yet I would have to purchase a whole pallet which is not an option as its three times the amount I need.
@ Lowes:
1-Plytanium 19/32 x 4 x 8 Pine Sheathing Plywood (
Shop Plytanium 19/32 x 4 x 8 Pine Sheathing Plywood at Lowes.com) $22
2- Plytanium 23/32 x 4 x 8 Pine Sanded Plywood (
Shop Plytanium 23/32 x 4 x 8 Pine Sanded Plywood at Lowes.com) $34
@ Local Lumber Yards
1- 3/4" Sturd-I-Floor $31
2- 1/2 CDX 5 ply $17
My current subfloor appears to be 3/4 plywood (picture attached):
I have a 5/8 dip in the kitchen that I plan to correct with 3 tap roofing shingles and the plywood.
I am looking for professional/experienced opinion on which of the above options would work and/or which options are a definite bad option. Everyone I talk to at the stores say any plywood would be fine. I would also prefer to use 1/2 or 19/32 rather than 3/4 if at all possible.
Thank you in advance for all the help as I just want to make the correct choice.
