Another huge problem...can tile go over an uneven wall??


A million things going wrong with remodel right now. I have a huge concern...The main plumbing stack has been relocated and is running behind where our cabinetry and backsplash will be. There is a part of the piping that is thick, where they connect 2 parts (forgive my lack of proper terms), and it ...

Lemme guess, bathroom originally didn't have a shower, and a previous owner added one on the cheap?
Before backer board, a wet-area tile job was done on a mud bed. Basically like plastering, but with materials similar to outdoor stucco, including the chicken wire. Tile was set in the final coat of mud, over the chicken wire. Tile over plaster was rare, simply because tile was seldom used in non-wet areas back then, other than by rich people.
As long as you have wall open and bathtub out of commission anyway, I'd strip the entire surround and get it over with. Odds are the plaster isn't quite flat, which will make the tile look funny, and a tile wall will be more prone to leaks than the nasty sheet-good stuff you tore down. It'll only be a few hours more work, and a few bucks more (Backer board and mud is cheap), but it will look better, and you will never have to mess with it again. And if this is an outside wall, stripping to studs will...

You won't have to mix mortar or learn how to apply plaster mud to the wall, you'll only need some hand and power tools along with a sheet of drywall. In just hours, your even plaster wall will be restored, looking like new.

Clear everything away from the uneven plaster wall and put a drop cloth on the floor. Put on goggles.

Strike a chisel against the uneven plaster wall with a hammer until it penetrates the wall.

Insert the blade of a reciprocating saw into the chiseled hole and cut out a square, a few inches larger than the uneven portion of the plaster wall.

Measure the square cut with a tape measure. Measure, mark and score a drywall sheet with a utility knife to create a patch the same size as the cut out square.

Insert the drywall patch into the square cut and fasten to the exposed wall studs with a screw gun and drywall screws.

Tape around the seams with drywall tape, then use a putty knife to spread joint compound over the...

Prior to the 1940s when drywall use became fairly widespread, homebuilders typically relied on plaster when constructing walls and ceilings. Builders erected slatted wood walls known as laths, which supported several layers of lime-based plaster. In many areas, installers added horsehair to the plaster mix to reinforce walls and ensure the finish would last. Before painting over traditional horsehair plaster walls, take the time to properly prepare the walls to maximize your results.

Major Repairs

Perfectly applied horsehair plaster is rough and rustic by nature, so the last thing you need is cracks and holes that add to these imperfections. Taking the time to prepare your plaster walls for paint helps ensure the paint will last for as long as possible. To fix major cracks and damage to the wall, you must first repair any structural problems contributing to the crack. This may include repairing floor joists below the damaged area, replacing missing or broken sections...

I have a plasterer in plastering my bathroom. (He is due to finish tomorrow (Saturday) and will want paying!
I don't know what I'm looking at, but even I can see the mesh joint tape showing through the ceiling and walls, even where ir is supposed to be finished.
It has been expensive to get done (old lathe and plaster completely removed, new board and plaster/skimmed,
but I am really concerned about the finish and he is going to expect payment tomorrow when he finishes off. I just not know what to do?

Dear John,
I don't know how you reply to answers, but you can see the mesh and it feels rough too, there are also 2 mil gaps between the new plaster and the architrave round the door, plus it now looks like two of the walls have nettle rash (lots of little bumps) I think I will phone another plasterer and get them to look at it, as I just don't know what to do with it, it was a proper plastering company, but the guy was a bit scary, the only good thing...

Many walls are somewhat uneven. They may have settled or bowed over time, or the plaster may be rough and uneven. If you're tiling over an uneven section of wall, the corners of the tiles may stick out slightly from the rest of the tiles; this is known as "lippage," and it can diminish the most professional of tile jobs. Lippage can be eliminated on most walls by hanging new drywall or backerboard before tiling. If you're tiling directly onto the wall, however, leveling clips and wedges will force the edges of the tiles together and create a smooth, even wall tile installation, no matter how uneven the wall is.

Measure the wall where you will place the tiles. Find the midline of the wall from ceiling to floor and mark it with a chalk line. You will lay out your first tile directly on this line, and your next tiles evenly out to each side to get a balanced installation.

Chalk off an area of equal width on the floor nearby and lay out the tiles in this space to practice...

Given that it’s a difficult job to do well, plastering or re-plastering an entire wall is not something to approach lightly.

First you must be sure that it really is necessary. And then you should check that there isn’t an easier alternative — drylining for instance.

Why re-plaster?

Patching a plastered wall is a great deal easier than re-plastering it from scratch but often the job that needs to be done needs more extensive work. Because if the patches are large or extensive it simply isn’t worth doing — you’ll never get a surface good enough to paint or wallpaper on.

Large scale DIY jobs present the same problem: if you have hacked the plaster off half a wall it will probably be better to replaster the whole of it rather than simply making good the damaged area.

Walls which are intact but have a poor surface because of previous patching could be another candidate. But in this case you need to assess whether it’s worth the trouble....

Working out how many tiles you'll need

Most modern ceramic tiles come in packs that cover one square metre. To find how many packs you need, just measure the height and width of the area you want to tile, then multiply the figures to get the area in square metres.

It's a good idea to allow 5-10% extra for cutting and breakages. If your wall has doors, windows or fixed cupboards, work out their area and subtract this from the total area you'll be tiling. It might help to draw a rough sketch of the wall and mark all the dimensions on it.

Setting out your tiles

Because of the clear grid pattern that's formed by the joints between tiles, it's really important to find the best starting point for your first row. It's no good starting in one corner and working your way across the wall - the corner might not be completely vertical and you could end up with tiny slivers of tile to cut at the far corner.

It's much better to centre your grid on the wall....

Swimming Pool Plastering Do-It-Yourself Project They said it "couldn't be done".
They said it was a job for "professionals only".
They refused to sell me the "tools of the trade".
They said only licensed contractors are allowed to buy "that kind of plaster".

I had Lowe's. I had Home Depot.
I had a wife and eight children to conscript.
I took the ultimate do-it-yourselfer's challenge.
