How to screw into veneer plaster wall without breaking plaster

What’s the Real Difference Between Plaster and Drywall?

There are a few things that make the two different, especially related to attaching things to your walls.

  • Drywall is usually 1/2” thick, compared to historic plaster, which can range from 3/4” to just over 1” thick.
  • Plaster is much harder than drywall
  • Plaster is more brittle than drywall
  • Plaster has lath (wood, metal mesh, or rock lath) behind it that supports it, whereas drywall has nothing behind it

All these differences mean that the two require different fasteners and fastening methods for decorating.

Can you hammer screws?

A hammer can be used to start a screw in soft wood in much the same way that an impact driver can start a screw (into wood) without a pre-drilled hole. Simply tap the screw a couple times until its point penetrates the surface far enough that it will grab when you turn the screw with a screwdriver.


How Damaged is Your Plaster?

Failing plaster creates a tremendous mess, which is why so many people throw up their hands and call a drywall contractor. If your goal is to save as much original plaster as you can, first identify how deep the damage goes.

Clips beacons plaster

Plastic mounting-clips for lighthouses KDM-2 is used when performing the rough plaster walling (basically, ceilings and walls). Consisting of 2 parts (clamp and base) structure is made of environmentally friendly and allows the polypropylene any variants beacons (A-frame, T-shaped and other). The base of the clip is mounted on the cap of the screw. The total thickness of the plaster layer should not be less than 12 mm (6 mm lighthouse and the same plaster).

Unlike beacons for plaster walls of metal, requiring a sufficiently large amount of time and appropriate temperature conditions, KDM-2 installed much easier. consumption of plaster much less – an average of about 24 kg per sq. m. BUT, so, attachment of this type can not only be mounted beacons, but also to save material and time, improve the efficiency of plastering work and get result fairly level surface, not using self-leveling mixture. = kKUIQPsWcyE

Proper installation of rails on the clip

To install beacons for plaster walls should be:

  1. Prepare a place for mounting rails, drilled for each six-millimeter multiple holes (usually quite 5 or 6) depth to 6 cm;
  2. Insert the prepared hole size dowels 6 x 30;
  3. Screw the screws in length 4,5 cm (or more, if the plaster layer thicker standard);
  4. With line and construction level hold alignment screw heads thus, so they were in the same plane;
  5. Wear on the screws, plastic clips;
  6. Fit the beacons, fixing plugs.

The ability to move the already installed guide ensures maximum accuracy of work. While no need to strictly control their position more and faster installation. The average consolidation takes 3-4 times less time compared to other fastening options. And due to the minimum thickness of the plaster, even when repairing an ordinary apartment, you can save 2-3 cu. m. plaster mix. More detail of plastic clips and how quick installation guide.


Two Methods for Filling a Crack

There are two methods for filling in the crack once the wall is anchored. They are:

The Inverted V Method

  1. Dig out the crack along its length in an inverted V shape and vacuum out any residual debris. This should create a toehold for the patch.
  2. Provided the crack survives without crumbling into chunks, fill and tape it much the same as though it were a drywall joint.
  3. First wet the lath and plaster around the cleaned crack to help the patch adhere (the old, dry materials tend to suck the moisture out of the new plaster before it can fully cure).
  4. Then fill the crack with a coat or two of stiffly mixed joint compound to raise and level out the crack.
  5. Also, take care that the new plaster attaches firmly to the lath by pressing the material through the openings in the slats. Otherwise, the repair will fail.
  6. Float the crack out with two thinner coats of joint compound, sanding between finishes.
  7. Finish with a final layer of joint compound or Easy Sand and touch up sanding.

The Bonding Method

Use a PVA (polyvinyl acetate) plaster bonding agent around the edges of the failed plaster and on any exposed lath before taping the crack. The bonding agent acts as an emulsifier to bond the new plaster to the old without the hit-or-miss method of wetting the old lath and plaster. Then fill in the hole as above. Allow each application of plaster to dry and sand between coats.

How Much Weight Can Plaster Walls Hold vs Drywall?

Both plaster and drywall can hold roughly the same amount of weight. A screw driven into a stud in both plaster and drywall can hold 80–100 pounds (36–45 kilos). Anchored screws or other fasteners set into the wall where there is no stud can hold up to 20 pounds (9 kilos).

  • Plaster and drywall can hold the same amount of weight.
  • If you screw into a stud in both plaster and drywall walls, you can suspend up to 100 pounds per screw.
  • If you use fasteners that do not attach to a stud, you can hang up to 20 pounds per fastener.
  • Use multiple screws or fasteners to hang heavier items.

You can increase the amount of weight you can suspend from drywall or plaster by increasing the number of mounts you put into your walls. If one anchored screw can hold 20 pounds, you can use two anchored screws to share the load and hang an object that weighs up to 40 pounds (18 kilos).

Tools For Plastering

Following tools are used for plastering:

  • Trowel.
  • Float.
  • Floating Rule.
  • Plumb Bob.

1. Trowel

Trowels used for mixing mortar. Trowels are 150 mm

Trowels used for mixing mortar. Trowels are 150 mm to 450 mm. A few of the above are blunt-ended, and a few are point-ended. A trowel is a small hand tool used for digging, applying, smoothing, or moving small amounts of viscous or particulate material.

2. Float

A float is used for spreading the motor on the surface of the wall. It can be of metal or wood. Wooden float is prepared by fixing the handle on a 10 mm thick wooden board. It is used to finish the coat. It is called skimming float.

3. Floating Rule

It is used for checking the level of the plastered surface between successive screens. Floating Rules are a special type of advanced rule that can perform complicated actions not possible with rules on interface or group tabs. Floating rules can act on multiple interfaces in the inbound, outbound, or both directions.

4. Plumb Bob

It is used for vertically of the plaster. Over and above this, spirit level, brush, set square, etc. are used for plastering. A plumb bob, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line. It is a precursor to the spirit level and used to establish a vertical or horizontal datum.

How much weight can a plaster wall hold

Answered By: Walter Ross Date: created: Jan 11 2022

Originally Answered: How much weight can a hollow wall/ plasterboard wall take? Your wall will be able to take as much weight as you can hang on it. Every 12″x12″ span of 1/2″ drywall can hold 40lb in pull out load, as if you were hanging from a ceiling. The other type of load is shear or pull down load.

Hanging Pictures on Plaster

Hanging pictures on a plaster wall is very similar to hanging them on drywall. You’ll just need some specialized tools and equipment to get the job done. However, you’ll find the job isn’t as daunting as you might’ve previously thought.

How to Hang Pictures on Plaster Using Wall Stud

Always pre-drill a pilot hole before driving any screw, anchor, or nail into plaster. If you attempt to drive a screw directly through plaster, you can cause cracks to spread across your wall. For best results, follow these steps:

  • A standard stud finder won’t work on plaster walls. You’ll need to use this magnetic stud finder.
  • Mark the location of the stud with a piece of tape.
  • Drill a pilot hole through the piece of tape and plaster. This will prevent the plaster from cracking.
  • Drive the screw through the plaster and into the stud.

It’s important to use a magnetic stud finder when working with plaster walls. Standard stud finders simply won’t work. Plaster is backed by wood lath, which will cause a stud finder designed for drywall to signal that there are studs anywhere you place it. A magnetic stud finder works by locating the nails that attach the lath to the studs. It’s the foolproof method for finding studs in a plaster wall.

Can I hang a TV on a plaster wall

Answered By: Aidan Sanchez Date: created: Nov 29 2021

Most mounts consist of two pieces. The first piece of the mount will attach to your wall. Use a drill and the provided hardware to mount it directly into the stud so that the plaster is not damaged. Attach the second piece of the bracket to your TV.
