Which side of plywood faces up?
This directs the worker on the correct orientation of the board when installing. The side with the stamp is the smoother side. When installed smooth side down, the rough surface will then face up and give the worker traction for safety.
How tight should tongue and groove be?
All it takes is 1⁄8″. The joint should be a firm press fit: If you have to knock the pieces together, then struggle to pull them apart, the joint’s too tight. A tongue that’s a hair too fat for the groove may actually seat, but it will stress the groove sidewalls and may, in time, prompt them to split.
Should tongue and groove plywood be glued?
The tongue or the groove does not need to be glued, although there is no reason not to. Some engineers require it in certain applications, but for standard subfloor applications none will be needed.
Should you lay plywood over plank subfloor?
Take time to make sure your existing planks are well secured in place. Repair any broken planks. Install a layer of at least ½” or preferably 5/8” ply over the existing planks. Like all wooden flooring products, it’s a good idea to acclimatise your plywood before laying it.
Do you have to use tongue and groove plywood for subfloor?
For subflooring, you use tongue and groove plywood. The tongue and groove are only along the 8 foot edges. On the four foot edges, your seams will fall on joist tops, so no need for tongue and groove.
Is it better to use OSB or plywood for subfloor?
The National Tile Contractors Association and the Resilient Floor Covering Institute both recommend plywood for subflooring and underlayment, because it doesn’t have the risk of swollen edges that OSB does. Plywood also has a slight advantage in stiffness, which means that subflooring panels need not be quite as thick.
Does plywood have a good side?
The non-construction grading for decorative hardwood plywood is an alpha character first for the good side, and a numeric character for the secondary side. A good face would be an “A” and a secondary face (the back) may be a 1-4. The higher the number, like “4” indicates plugs, defects of different kinds, etc.
Does it matter which way you lay plywood?
It is exceedingly important that the first whole line of plywood sheets be perfectly straight and square. Each subsequent piece of plywood will depend on the first piece being installed correctly. If you do this properly, you’ll have a beautiful plywood subfloor.
How can you tell if plywood is good?
There are numbers of things you can check in order to examine plywood quality.
- Check whether plywood have wood face veneer or not.
- Check plywood surface is smooth and doesn’t have ups or down.
- Check all four corner of plywood & make sure it has no thickness variation.
- Check Weight of plywood by lifting from one side.
Does the tongue or groove go against the wall?
Which side is the tongue, which the groove, and which goes first during installation? The tongue is the side that you will want to place against the wall as you start your laminate-flooring installation.
Do you nail into the tongue or groove?
For tongue-and-groove flooring, drive a nail at a 45-degree angle through the tongue, then conceal it by engaging the groove of the next board. Be sure to countersink the nail — drive it slightly below the surface of the wood — to prevent interference in the joint.
Where do you start when laying tongue and groove flooring?
Start at the corner of the room and place the first board with the tongue facing toward the wall. Be sure to leave a gap of about a ½-inch so the floor has room to expand and contract. 5. Place the second board next to the first so the shorter ends touch, and pull the second piece as close as possible.
