Underlayment for laminate


Where is the springy area? Is it along a wall, in the middle, etc......

I had the same situation when I installed some Laminate recently in my own house And the biggest spring was in a couple corners. Normally I would want to do it right but this room does not see too much use so I left it be. If you step directly in the corner it drops a good amount but it is not often that happens.

If it is an area of traffic I would do it right and level it out.

It's not in a corner, more in the center of the room (not exactly the center though...)
It's the family room, and we want to make it a TV room....I would say traffic will not be too high
Some pieces of furniture may put "pressure" on it, then it won't move anymore....Not sure

Underlayment for laminate


Well, I think I will remove the laminate already installed and I will use some self-leveling mix to patch the lowest areas....1 bag should be enough and I will prepare some mix by smaller portions (not the whole bag in 1 shot)
It sucks, but I don't like the way it is right now!!!

By the way, where can I find a long (6 or 7 feet) aluminum rule to apply those patches? I didn't find any at HD.....

I think I looked everywhere at HD: lumber, building material, drywall, paint, hardware...............nothing
I just bought an aluminum angle bar (8' - 1,5" x 1,5" and 1/8" thick)
But it's overprice I think (~$40 with tax)
What do you mean by art store?

Underlayment for laminate


Let’s say I want to make a wood sub-floor based on sleepers + OSB boards
Sleepers being attached to the slab with Tapcon screws, and OSB glued and screws onto the sleepers
Sleepers every 2 feet with some foam in between….
I was thinking to use 1” x 4” sleepers (2 x 4 will be too high)
1) Is it OK to go with 1 x 4?
2) Should I use pressure-treated or regular white pine boards?
3) Do I need the grooved and tongued OSB 4 x 8, or can I go with squared edge as long as there are sleepers under each edge?
4) What shouldbe the minimum thickness of the OSB?

Thanks

Does that mean 1" x 4" is not feasible at all?

I’m from Canada; I don’t know what JoAnn is? If it’s a good art store they should carry large rulers. You should have a Michaels, can try them. I’m just thinking out loud as I have seen them around.

Underlayment for laminate


My idea was to have the moisture barrier (6 mil film), anchor the sleepers (1" x 4") with the foam in between, resting on the moisture barrier, and on top of it OSB or Plywood
Now, do I need pressure heated sleepers or not?

3 more questions:
1) Do I need to leave a gap (1/4") between the walls and the plywood?
2) Do I need to leave a gap between each plywood board (knowing they will be glued and screwed on the sleepers)
3) Is groove/tongue boards mandatory or not?

Thanks
