There are some homes that are impossible to sneak in and out of. Not because of the latest in high-tech security or an iron-clad exterior; these homes have squeaky subfloors and noisy stairs loud enough to wake the dead. I also read somewhere that the new layer of plywood on top should straddle 3 of the sheets undernieth, I think it was Armstrong years ago. Nails should go through the face of the boards and nails should be long enough to penetrate the sub floor by at least 1 inch. There are ways to raise a floor lever more than 1/2″ but not necessarily with cement board.
As we now want to convert it to a bathroom, we want to put tiles with it. The floor is concrete so we don’t have much problem with it. The problem is the wall. It isn’t, but you’ll need a dose of common sense to execute the job of installing an attic floor properly. I also noticed there is no moisture barier beneath your floor which could damage and warp the wood if water or moisure pushes through the concrete.
The biggest thing for starters is to make sure your subfloor is level and your floor joists are strong enough to handle the weight of the wood, especially if you’re laying it down over an old floor. Loose or damaged subfloors can cause squeaking and affect the performance of the finished flooring that is installed over it. However, for glue-down applications, you may need to remove vinyl or other floor covering, because they could affect the bonding of the adhesive, or they themselves may no longer be wellbonded with the subfloor. If you follow all these steps, you’ll have a stiff, monolithic, crack-free floor.
Use 1/2-inch spacers along the base of the wall to provide an even expansion gap between the flooring and the wall (this gap will be hidden by the base molding after installation). BTW I have used construction adhesive to glue pressure treated sleepers to a concrete basement floor. You could refinish the floors yourself or if you are concerned the floor is unstable and needs replacing I would indeed call a local professional to inquire not only if the floors can be refinished but if a new floor can be laid over the old floor.
After each sheet of plywood is layed down, I went and marked the open edge, with a mark centered on the open floor joist. If your sub floor is uneven we recommend you use a good-quality latex self-levelling compound, alternatively smaller uneven spots of more than 3mm can be filled with a rapid-drying deep-fill compound. The sturdier your subfloor is, then the less problems you should have with your hardwood that you install.
It also is now the current height of the oak flooring in the living room and the hallway that adjoin the kitchen/foyer that I’m tiling. There are unique challenges in every plywood subfloor installation, including important building codes specific to your area that no single article could completely address. I just used the 80 grit in the big flooring sander, but if you wanted a bit smoother finish, I’d recommend going over them again with a 120-150 grit.
Proper selection and installation of underlayments and subfloors is crucial to the proper wear and stability of any flooring. Install subsequent rows using the hardwood hammer while respecting the rules for alignment joints and expansion joints. To be fair, my floor was for a home office-the workshop remained concrete until it became carpeted as we moved recently.
A friend of mine said that the people who laid one of her floors used glue on the stairs, but it took days for it to dry, even in dry climate. Check for cracked or loose tiles and grout — these could be signs of a poor floor condition caused by settling which could cause problems for your laminate floor, too. The only way to do the job right is to vapor tight the areas and float it out for a true install that will live longer than most people will own the house.
You also need to make sure the floor structure is strong enough to support the weight of both the tile and wood. Starting against the longest continuous wall, roll out the vinyl flooring face up and lay it in the space it’s going to cover, taking care not to twist or damage the surface. Once the joints are filled, turn the float at a 45 degree angle and begin working across the tiles from corner to corner, removing any excess material. Chemically treated plywood is available for constructing porch decks because it resists moisture better than standard plywood.
Not only can this lead to mold/mildew between the concrete and your new floor (in the carpet), but the dampness will ruin your new floor. The sleeper system that entailed fastening 2′ X 4’s to the concrete laid on their side has faded from use. Because this floor may be exposed to weather before the second floor and roof can be installed, we covered it with Zinsser Shellac Shellac helps temporarily prevent water penetration on the surface and sides of the plywood. It aids during installation if the joists are installed exactly 16 inches on center throughout the floor.
At 16″ on center, there will be 7 joists under each piece of plywood, and each piece will end in the middle of the next joist. While Dalley and Bath didn’t want to install it in a high-traffic area, it made for an affordable, clean and warm floor for their master bedroom. Nails, I think screws would have split up the plywood (it was really thin plywood) and they would have also taken forever. If I lay the ply do I now need to leave a gap between the ply and the strips of wood around the edges or is that not necessary. In fact just this last year we installed more plywood floors in two of the bedrooms.
We pulled up the cracked tile floor and the cement board that had not been laid properly (using thinset). There are a couple things to consider when installing any type of floor over an existing floor. It made the room GLOW – it made a bungalow bedroom look like a million bucks, and it was mere hundreds of dollars for 400 square feet versus thousands for other type of flooring. My big worry would be dirt and debris falling into the larger and more irregular cracks unlike those of regular flooring.
I’m sure most shop floors being built do not require the insulation value versus those that do. I would definitely be looking at products like this if my situation were reversed. This will help you work out where the other tiles will go. To do this, dry-lay some of the tiles from the centre line to check how they fit at the skirting. There are also other trades between plywood and OSB See that article for more details.
I used BM porch and floor paint in White Dove and sealed it with satin Varathane Diamond, and cleaning with a steam mop is pretty easy. Get an ‘alkali resistant’ mesh tape – similar to drywall tape – and place it over all your seams in your floor. What you want to avoid are narrow slivers of tile around the edge of the room or tiles of differing widths on one side of the room, versus the other. The original floor was concrete over bridged joists in this case all the bridging and sister joists were 3/4″ The concrete was 1 1/2″ thick w/ tile. I’m ripping out ALL the flooring (main carpet, bath linoleum, kitchen laminate, etc).
I used 2” Green exterior screws with T-20 star drive heads to secure the plywood to the 2X4s. Yes, we face-nailed the boards, and no, I’m not going to fill them in. If anything, I think the nail holes will keep the floor from looking too even and perfect, which was my biggest concern putting brand new, smooth wood in an old house. Your vinyl flooring is suitable for use with underfloor heating, as long as the temperature of the subfloor does not exceed 27°C.
When securing cement backer board to a plywood subfloor before tiling, screws provide better holding power and have less chance of working their way out than roofing nails. If this is impractical, however, it is possible to install on top of existing tiles, so long as they are securely fixed and in a good state of repair. Once laid into the thinset bed the floor becomes a solid, fully supported substrate for your tile – that’s what you want.
When I phoned a flooring merchant, he said I needed 9mm ply or is he just trying to sell me something that’s going to cost more. When necessary, sand the subfloor near joints; install extra blocking and re-fasten the subfloor to flatten uneven areas. I used a foam underlayment for my Pergo laminate flooring years ago, and it also squeaked. If you are laying on a concrete floor, the moisture level should not exceed 75%RH when tested with a hygrometer in compliance with BS8203-4; 2001. If you have some handy, put an extra layer of plywood underneath your linoleum as you cut it to avoid gouging your floor.
My thinking was that screws would be overkill, take longer, and might split up the plywood (its very thin plywood). The idea is to get the plywood fastened and take one last look before you fasten it completely. Annoyingly, the plywood sheets had all had several stickers (including a stupid, pointless QR code that NO ONE WILL EVER USE, EVER) on the GOOD side, and no amount of picking, scraping, Goo-Gone-ing or kerosine-ing (!) could remove them.
We stacked the plywood into 2 piles downstairs and continued working on other parts of the house first. In the case of the laundry room floors condition….measuring was reduced to guestimation and aligning the tiles with the entrance which is the most visible area and making sure the tiles would be hidden under the strange green faux grass strip that is on the edge. Snap two intersecting lines over the surface of the floor with your chalk snapline, dividing it into four equal squares. Cork can also be used to raise the level of the sub floor to make the various floors of a home the same height.
