Drywall

Sheetrock, drywall or gypsum are insulators.

Ethyl mercaptan is known for its strong odor, which can linger in porous materials like sheetrock for an extended period, potentially weeks to months. Proper ventilation and cleaning with odor-neutralizing solutions can help speed up the dissipation of the smell.

Fire-rated sheetrock is designed to provide protection against fire. Although it may char or be damaged by fire, it is designed to resist burning and reduce the spread of flames, allowing for more time to evacuate a building in case of a fire.

To remove a soda stain from drywall, start by mixing a solution of warm water and mild detergent. Gently scrub the stain with a sponge soaked in the solution, being careful not to damage the drywall. Rinse the area with clean water, then dry with a towel. If the stain persists, you may need to repaint the affected area.

Drywall mud typically weighs around 8 to 12 pounds per gallon when it is fully mixed and ready for application. The weight can vary slightly depending on the specific type and brand of drywall mud.

A standard sheet of drywall typically weighs approximately 50-80 pounds.

It's calcium sulphate dihydrate, or 'Gypsum'.

To clean muriatic acid off drywall, you can neutralize it by sprinkling baking soda over the affected area and then wiping it clean with a damp cloth. Make sure to wear protective gloves and eyewear during the cleaning process to avoid exposure to the acid. It's important to act quickly to prevent damage to the drywall.

By passing an electrical current from one pin to the other. The greater the moisture content, the higher the resistance. By measuring the resistance, it gives an estimate of the average moisture content. I think.

2009/03/14 - Correct, but exactly backwards .... Moisture (water) can be a conductor. Dry wood is an insulator. The higher the moisture content, the lower the resistance and vice-versa. Wood with a high moisture content gives a low resistance to the tester and conducts the test voltage better.

No, drywall installers do not inhale carbon dioxide from drywall. Drywall is primarily made of gypsum, a mineral that does not release carbon dioxide when installed. However, drywall dust can be a respiratory irritant, so proper ventilation and personal protective equipment should be used to avoid inhaling dust particles.

To remove liquid nails from drywall, you can use a putty knife or scraper to gently pry it off. If it's stubborn, you can try heating it with a hairdryer to soften it before scraping it away. Once removed, you can sand the area to smoothen it out.

hello, i'm an apprentice carpenter, so to say the least.. ive spent a fair bit of time doing this tedious job. i find that some of the best methods to remove dywall mud from concrete depeneds on two things, how much mud is on the concrete as well as how porous and gritty the concrete is. -->try using an abrasive pad along with a vinegar/water mix in a spraybottle.(half/half) -->use a putty knife, etc to scrape off the large chunks of mud -->razor scrapers work very well, however it will still need to be cleaned with either water or a mixed solution. -->sometimes just an abrasive pad alone will remove the mud -->sanding sponges work great, just dont use them in wet conditions (after spraying a wall, etc, it will clog the sponge..)

Pre Work is the key and sometimes that is not enough sometimes luck is your best friend,If there is no access to get above,or if you are between floors, 1st it is best to know wich way the joists are running even then contractors but boards in for stronger support, they can be a problem themselves, 2nd use a stud finder to locate the joists you need to how to use this tool or have someone do it, who works with one a lot, I am sure you have an a plan where you want the lights to go, put electrial tape on the ceiling where you want the pots to go, then from the farthest distance use the stud finder to see how much wood will be in the way and start working toward the wall where the switch will be installed to control the lights, getting the wire from the ceiling down to the switch a lot of times you have to make a hole there. then you should have drill bit extensions to allow you to drill into the joists for the wire to be fished thru it is not uncommon for the bit and extenstion to get stuck in the joists and they are left up there. The goal is to go from pot to pot without putting holes in the ceiling, however it is not uncommon to have to make a hole, if you have plaster ceilings, you are going to make a mess, just a heads up, drywall can be fixed, if you have textured ceilings they can be matched a lot of times however the whole ceiling has to be repainted. One other item to remember is this is not a one hour job plan to be there quite a while just getting the wire from the pots to the wall could take hours. Depending on how many pots you are putting in sometimes it is eaiser to run two cables rather than one cable to the wall.

Common chemicals used to clean up drywall dust include trisodium phosphate (TSP), vinegar, and dish soap. These chemicals are effective in breaking down the dust and helping to remove it from surfaces. It is important to follow safety instructions and proper dilution ratios when using these chemicals.

No, eating gypsum drywall will not get you high. Gypsum is a mineral commonly used in building materials, and ingesting it can be harmful to your health. It is important to avoid consuming any non-food items.

Homeowners, contractors, inspectors, and real estate professionals may be aware of Chinese drywall issues. Manufacturers and suppliers of building materials may also have knowledge about Chinese drywall due to the recalls and lawsuits linked to its use.

Very little drywall from any era contains asbestos it is actually much more common 75-90% depending on the region in the texture and applied joint compound which folks often confuse with the drywall. Visually it looks no different than non-asbestos containing texture or drywall. The only way to confirm asbestos content, if you don't know precisely what product was used (manufacturer and model, etc.) is to have the proper number of samples collected by a qualified asbestos inspector if required by local regulations and submitted to a lab to be analyzed by polarized light microscopy.

You prime it with drywall primer.

Yes, it is as toxic to animals as it is to humans.

Carpenter ants do not eat drywall or wood. They hollow it out to nest in it.

That's the standard size available in almost every building products store.

There are no real 'dangers' because it tastes awful - so I think it would take extreme effort to eat enough to even make you sick. I have heard of dogs liking to eat it and this should not be allowed.

The glue and paper will make you sick. The gypsum board will do nothing but fill you up; gypsum is a natural filler used in a number of foods.

I have seen a crew do it in one day for $700 here in CT. (and they were working with fire code sheet rock). This was strictly to hang it, taping was not included.
