Hi Dawn, this is correct. Usually underlayment will float under the floor without any need for adhesive. Hi Seth, thanks for the question. We do not do installations, so I am not sure what a rate would be.
Hi Karen, the adhesive you use should protect against water damage. You will not need a vapor barrier if you plan to glue your vinyl. We are putting the floor on concrete with a 6 mil vapor barrier. I want to put us all over the floor but will need to place cabinets on it as well.
I know that it is recommended not to place cabinets on the floor due to buckling. If we glue it down then we can. My question is, still use the vapor barrier and slur on it? Thanks for your assist! Hi Gary, thanks for reaching out.
When installing on concrete, we recommend using a moisture barrier to prevent moisture from seeping up from your subfloor and sitting beneath the flooring. We are in a situation similar to An August 11 post.
The subfloor was glued and screwed with 3. The floor was not finished but was in like new condition, before it was lightly sanded last week, to eliminate high spots.
It is very dry and always has been. Checking with an 8' level, it is fairly flat in all directions, including circles. Finish flooring will be 4" wide, random length White Oak planks nailed with L shaped cleat nails and tarpaper underneath the oak flooring. The underlayment will be laid in the same direction as the subfloor, perpendicular to the floor joists but with long edges offset halfway across the sublfloor panels and the 4' wide underlayment ends offset from subfloor ends by two joist bays plus 4" to prevent any seams from lining up and for max floor stiffness.
The insulated crawl space is very well vented, exceeding code, and there is a 6 mil vapor barrier in the crawl space. All wet work is done and eaves troughs are in place. Our big problem is if we should glue and screw the underlayment to the subfloor the same way the subfloor was installed, only with more glue, so the underlayment acts as an extension of the subfloor? There may be a small amount of tile near an entrance way to control mositure at the entrance.
No more than sq. Not in both rooms. Comments and suggestions are hoped for. It is a big problem for us right now and is holding up the flooring installation. Worried about squeaks and movement of the underlayment. I'd fill the low spots with a self leveler and then put on the plywood with screws and glue. Disoriented strandboard needs all the help it can get and you can never have too stiff a subfloor. Tarpaper really does nothing structurally.
You certainly don't want any between the two subfloor layers. You don't want them to MOVE relative to eachother. Hi Ronnatalie, Thanks for the reply and the advice. Would you screw the underlayment through the subfloor and into the joists? Would that help prevent movement of the panels? Also, what glue would you use? I have heard you can't use Titebond II or III because it is a brittle glue and it makes "crackling sounds" when you walk on the floor.
Is some other kind of glue recommended? Please help! How can I make my bedroom look cosy and just better! Cabinet cracks on screw holes: acceptable? Sound proofing our floors. I use heavy duty construction adhesive, nails and special purpose screws for the subfloor.
If you need access below, you can't pry it apart, but have to cut it out. Glue and screw the underlayment as well. Use professional quality hd adhesives. Here is a link that might be useful: Professional quality construction adhesives. You guys are great. This is a wonderful site. I really appreciate all your advice and I might be able to get this done yet. How would you apply the adhesive? Is there a less expensive way? Can we just use pro adhesive in a large caulking gun, like from Home Depot, and make zig zag patterns, then screw the underlayment down, or will that cause air spaces where there is no glue?
Could those air spaces allow the underlayment to move slightly when the floor is walked on? How have you guys applied the glue? Just a thought. This was over 20 years ago and the floor is still tight. However, the underlayment we just screwed not glued to the subfloor and into the joists. We are glad because now 20 years later we are removing rugs, underlayment and putting down solid oak flooring. Allow to dry completely about 30 minutes.
Can you glue plywood to concrete? Plywood can easily adhere to concrete. Plywood is often used as a sub-flooring. It can be installed on top of concrete before hardwood flooring or another type of material is installed. One way to attach plywood to a concrete surface is to screw it into place with concrete fasteners. How do you install plywood underlayment? To avoid damage to the surface, install underlayment immediately before laying the finish flooring. For maximum stiffness, install underlayment with the face grain perpendicular to floor joists, and offset underlayment panel ends from subfloor panel ends by at least one joist space.
Can you glue vinyl flooring to OSB? Most flooring vinyl flooring manufacturers do not allow direct glue down directly to the subfloor. Is tongue and groove necessary 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. Once the adhesive dries overnight, the material will be ready for use. The adhesive will reach its complete strength within 7 days. Actual drying time may vary with temperature, humidity and materials used.
A thicker subfloor takes a 3-inch screw. Use a heavy-duty drill to drive Phillips head wood screws through the subfloor into the floor joists. Drive the screws approximately 8 inches apart. To make the job easier for you and the drill, we suggest that you pre-drill holes before screwing the subfloor down. Plywood has been a standard subfloor material since the s and remains the preferred subflooring for many builders.
It held pounds on the wood block and 92 pounds on the PVC block. Does subfloor need to be glued? Category: hobbies and interests woodworking. The answer: Glue. Although using a subfloor adhesive is not required by code, it is a standard practice that can help prevent floor squeaks by reducing the chance for movement at the panel-to-joist connection. A quality subfloor adhesive will also increase the overall stiffness of the floor.
