Replacing lath and plaster with drywall modernizes your home, improves insulation, and can be a more stable option.
We renovated an older house. Short answer, if you intend to stay there a long time, it is worth it to remove all the plaster and lathe, down to the framing, in the entire houe. You do not know what (shoddy) framing and modifications are there, and it will make the insulation, wiring, and plumbing sooo much easier.
Additionally, there are some advantages to traditional lath and plaster construction. Most importantly are its sound-proofing properties and ability to delay and deter the spread of fire.
Unfortunately, there wasn't a regulated or realistic way to ensure that all older buildings using plaster walls were asbestos-free. Asbestos was commonly added to plaster until the late 1980s, as it was seen as an inexpensive way to add to the plaster's insulation and fire-retardant properties.
When deciding whether to remove the existing plaster or not, the key question is what condition is the existing plaster in? If it is cracked, covered in residual coatings, or has lumps and bumps, you should remove it. Trying to plaster over these problems could cause structural issues with the new layer of plaster.
Generally, a plaster should stay on until the wound is sufficiently healed, usually within 1 to 7 days. It's important to check the plaster regularly for signs of wear, such as looseness, soaking, or infection. Adjust the plaster as needed and follow any specific instructions provided.
The cost of professional plaster wall removal and replacement with drywall typically ranges from $1.60 to $3.80 per square foot. You'll also need to factor in the costs of materials and disposal, which vary by location.
Reproductive problems, high blood pressure, nerve disorders and concentration problems have all been linked to lead poisoning. Most American homes containing traditional plaster were built before World War II, meaning they are candidates for lead-based paint.
Asbestos has been used in a variety of other building materials, for example, in decorative coatings such as textured paints and plasters. These are still widely in place but supply and application has been prohibited since 1988.
Lath and plaster methods have mostly been replaced with modern drywall or plasterboard, which is faster and less expensive to install. Drywall possesses poor sound dampening qualities and can be easily damaged by moisture.
Lath and plaster walls have an irregular surface that are a problem for stud finders. As a result, your stud finder can show a false positive (a stud indication when it is actually not a stud) when it finds an increase in density, even if it is just a glob of plaster.
A gravity toggle is a strong fixing for plasterboard or lath-and-plaster walls. Basically, it's a screw with a swinging metal bar (toggle) attached. When you insert it, the toggle swings down and grips the back of the wall. The toggle is lost in the cavity if you remove the screw.
If you're removing plaster and lath from both sides of a wall, do this: Completely strip one side of the wall, then attack the other side from behind. I like to stab at the lath with a square shovel, right next to studs. As the lath loosens, the plaster breaks away and falls off.
While they may sound concerning, most plaster cracks are extremely common and normal.
N95 masks do not protect against gases, vapors and cannot be used for asbestos, and they do not provide oxygen.
Your older home probably did not come with an inventory of all asbestos containing materials, but if the house in which you live was built before 1980, there's a good chance that you'll find asbestos containing materials in the walls, ceiling, roof or floors – or all of the above.
Popcorn ceilings contained asbestos for its resistance to heat and corrosion. Asbestos is no longer added to popcorn ceilings because it's a known health risk. The chances of your ceiling containing asbestos are low for any installations in the late 1980s or after. Newly constructed ceilings don't use asbestos.
As long as they're in good shape, it probably makes sense to leave them alone. For many homes, plaster walls are a big part of their appeal. If this is true for your home, the best way to ensure they stay in great shape is to regularly inspect them and have any cracks repaired as soon as you notice them.
Because they contain high levels of sulphate, you must separate plaster, plasterboard and other gypsum products from your general wastes. You must dispose of non-hazardous gypsum-based materials in landfills for non-hazardous waste, in cells where there is no biodegradable waste.
It will cost more than $10,000 to drywall over the walls of a 2,000-square-foot home. Let's say you've researched replacing lath and plaster with drywall and are confident in your ability to do it. The average cost to have drywall installed in place of plaster, if done by a professional is $1,020 to $2,800.
Removing lath and plaster can expose you to dust and potential allergens. Mitigate these risks by ensuring good ventilation, wearing protective clothing, and conducting lead or asbestos tests if your house predates 1978. Anticipate structural integrity risks by consulting a professional when in doubt.
Instead of tearing out an old plaster wall, you could save quite a bit of mess by hanging drywall over the existing plaster wall instead. Removing plaster does produce significant dust and loose chunks of plaster and lath. However, by placing new drywall over your plaster, you won't have to deal with a big mess.
It is likely that if lath and plaster exists already, then it will need to be replaced like-for-like. If listed status is not a consideration and overboard is seen as a solution, care should be exercised to avoid damaging existing pipework and/or electrical cabling within the ceiling voids.
