How to mount TV in old drywall or plaster wall [duplicate]


If any type of drywall anchors are failing me, I immediately switch to toggle bolts. The down side being that if they also rip out they're going to pull off large sections of plaster. Finding the studs is always better.

To find a stud without a stud finder, try 3" screws every inch or so until you find one and then try measuring to help find the next, usually they're on 16" centers. If it's a small section of wall, there might just be one in the center or they might have split the difference and used two. It's also entirely possible that on a 32" wall there isn't one.

If you're willing to poke a hole, 20 little pinpricks should be no problem and if you're lucky the mount will hide them...

How to Install a Wall Mount on a Lath & Plaster Wall

Installing a wall-mounted unit of any type on plastered walls is different than installing a wall mount on drywall. If you do not use the appropriate anchors, your plaster will crack, and your unit will come loose or fall. This is particularly true i[More]

How to install the TV mount on the aluminum studs

Flat-screen televisions can be mounted on a stand or on the wall by using a bracket. Most wall-mounted brackets are secured to the wall with screws that go into the wood studs. However, some walls may not have wood studs and instead use a metal or al[More]

Mounting an LED, LED & Plasma TV on Plasterboard or Partition Walls.

To see our full range of flat screen TV wall mount brackets, please CLICK HERE

We’re often asked if the newer lighter weight large flat panel TVs can be mounted onto a plasterboard wall.

As we’ve covered in the past, mounting a TV onto a partition or plasterboard wall can be perfectly safe when using a flat or close fit wall mount bracket secured to two or more wooden studs behind the plasterboard.

As large screen LCD and particularly LED are much lighter weight than their older Plasma counterparts, it’s becoming more possible to mount them on extending arm brackets, or those that allow the TV to turn left or right, onto a plasterboard or partition wall.


If you’re able to strengthen the stud-work behind the plasterboard and add an MDF or wooden mount plate, supported by...

Once the surface is covered, go back over it, smoothing the plaster to an even thickness. Do not try to achieve perfect smoothness yet (Image 1).

Leave the plaster to dry for another half hour, until it is harder, but still slightly damp (Image 2).

Sweep a clean, dampened trowel blade across the entire surface, smoothing the plaster and redistributing any excess to fill small indents. Hold the blade at a slight angle with only one edge on the plaster to achieve a smooth finish (Image 3).

Leave the plaster to dry for at least half an hour, until the surface is firm enough to touch without moving the plaster, but is still damp. Repeat the smoothing process, again using any excess surface plaster to fill small depressions. If necessary, use a wet brush or garden spray gun to dampen the plaster as you work. Aim for a smooth finish at this final stage; it is more effective than trying to sand rough plaster when dry (Image 4).

Use a small, damp brush to finish...

covering a damaged rendered plaster wall with plasterboard or drywall

Renovating old homes with rendered plaster walls can appear quite difficult. Patching up a rendered plaster wall, like shown here, with sand and cement, will not gaurantee a great finish.

The answer is to stick plasterboard or drywall over the wall to cover up the render, all gaps and cracks.

Where you have un-even surfaces, it is neccessary to glue plaster blocks on the wall to even out the surface before you stick on plasterboard or drywall.

To stick plasterboard or drywall sheet to any masonary surface, you need to use either, cornice adhesive or masonary adhesive. The adhesive needs to be mixed to a fairly stiff but not dry consistancy

Daubs of adhesive should be a uniform size, small in area, but very proud of the wall. This helps to get the sheet level.

Care must be taken when placing the sheets, so that they don't slide on the adhesive daubs. The sheet should be...

Removing plaster from walls is not a difficult job but is time consuming and messy. Behind the plaster walls are narrow strips of wood called lath. The lath, nailed directly to the wall studs, supports the plaster wall coat. After you have removed the plaster, you can leave the lath in place if you wish. The lath provides a solid, stable foundation for the drywall boards. If you intend on snaking electrical wiring, pipes or insulation between the wall cavities, however, remove the lath for easier access to the cavities.

Remove the Plaster

Strike the top center of one of the walls with the hammer or crowbar, punching a hole through the plaster coating until you see the lath beneath. Insert the claw end of the crowbar into the hole and drag the claw through the plaster in a downward motion. Create a vertical gash from the ceiling to the floor into which you will insert your spade.

Position the large trash can beneath the gash in the wall. The can will catch a...

Many people believe that "plaster wall repair" is an oxymoron. They feel that plaster walls cannot be repaired.

It is true that plaster walls can be difficult to repair--especially if they are too far gone. Like rust on a car, you need to strike at the first sign of problems.

Fortunately, you do not need a special plaster repair kit. All you need are simple drywall tools that you can easily and cheaply obtain at a home improvement store.

Why Plaster Is Harder to Fix

With drywall, it is often more expedient to rip out entire sections and replace with large sheets.

As difficult a material as it is, drywall does offer some advantages over plaster when it comes to repairs. It is possible to remove only the section that needs fixing (plus a few inches beyond), without the entire wall collapsing. The other advantage is that drywall has no backing. Once you cut through drywall, there is nothing behind it except for studs and insulation. It all removes...

I know you're worried about how the top coat/finish will look but you should consider what's underneath that, first.

Plaster is rarely one coat, almost always two, or even better, three. Each applied separately and left to dry before the next is applied. The different coats are made of slightly different materials as they have different purposes, too.

But the first thing to think about is the lath. I assume you are talking about wood lath?

You said you have bonding stuff, but that's not going to be sufficient to stick the plaster to the lath. It's really intended to stick plaster to plaster, at the edges of the repair, which except in really small repairs isn't enough to secure the plaster to the wall.

Plaster works largely because it is mechanically held to the wall when some of the first (deepest-in) coat is squeezed through the openings in the lath and blobs of it form behind it within the wall cavity. When you tore the old plaaster out, you no doubt...

Plaster is an ancient building material, used for centuries, and once was standard for most house walls in America. It has largely been replaced by drywall or plasterboard, which was originated by U.S. Gypsum Co. as Sheetrock. Drywall is much easier and cheaper to install than plaster; but plaster conveys an aura of elegance; many homeowners like to add plaster for a distinctive look. You can plaster a ceiling in the traditional way or you can short-cut it by putting plaster over a drywall ceiling. The look will be similar.


Cover the ceiling with oriented strand board fastened to ceiling joists with a hammer and galvanized nails. Staple a waterproof membrane such as polystyrene over the OSB with a construction stapler and nail metal wire mesh lath on top of the membrane, as tightly as possible.

Mix plaster in a large container; use a type called "scratch coat" and mix it so it spreads easily but will stand on its own. The consistency is...

The texture was first applied, and then partially trowelled flat. The process is in three steps: 1-finish coat plaster the wall, and produce a smooth surface. 2-apply a slurry of finish coat plaster, and pull the texture, with a trowel. 3-trowel the textured surface enough to smooth out the peaks, but not enough to fill the valleys.

I don't know why the texture layer is separating from the smooth plaster underneath. Usually the texture sticks very well to the substrate.

If you are patient and persistent, you will be successful at duplicating this surface texture. You might have to scrape off the first few attempts, and get back down to the substrate. There is a learning curve. The finish coat plaster is thinned a bit with water, to make a slurry. It will take trial and error to get the viscosity...
