Drywall
Drywall has several common names, such as gypsum board and sheetrock. It is mainly used in the construction of walls, but also has other uses. A plaster is made of gypsum, poured flat and smooth, and then wrapped in paper. The pieces are joined with strips of paper, and cemented down with a compound known as "mud." After the mud is dry, it is sanded and the wall is finished with paint, texture, wallpaper, or a variety of other creative means.

How do you waterproof drywall?
To waterproof plasterboard or drywall wall linings, cover them completely with a waterproof material. Materials that can be used include:
* Acrylic or fibreglass sheet: ~4mm thick stiff solid acrylic/fibreglass sheets that need special jointers and/or sealant at all joins and are glued to the wall lining. Use details provided by the sheet manufacturer. Sealant will need replacing after some years, and can be a mould problem. Sheets require careful cleaning to avoid scratching. Many preformed shower cubicles are made from these materials.
* Pre-coated fibre cement or oil-impregnated wood-based fibreboard: These are also ~4mm thick stiff sheets that need special jointers and/or sealant at all joins and are glued to the wall lining. Use details provided by the sheet manufacturer. Sealant will need replacing after a some years, and can be a mould problem. Sheets require careful cleaning to avoid scratching. * Wall vinyl :~1mm thick vinyl produced specially for wall use. Joints need to be welded to seal and all details must follow the manufacturers instructions. Welding is solvent rather than heat based and these joints are critical so this skilled job best done by experienced tradespeople. Special jointers are available to join wall vinyl to thicker floor vinyl. Cleaning is similar to floor vinyl. * Waterproof membranes with protective covering: Sheets of membranes are lapped and glue or tape sealed. They can be self adhesive or glued on to the substrate. Liquid applied membranes are painted on to the substrate. The liquid applied membranes can be applied to complex shapes. Glass fibre reinforcing is applied between coats, to the joints and corners of substrates to strengthen the membrane. These membranes are then covered it with tile or vinyl as a protective layer as the membranes are not a durable wearing surface.
Note: Glazed ceramic tiles are not waterproof. The glazing is waterproof but the tile is porous. Fully vitrified or porcelain tiles are waterproof, but no grout is truly waterproof, and grout will also get microcracks over time.
Tiling over thick, dense, reinforced cement plaster is a system that has been accepted as water resistant by some because the tiles shed the bulk of the water and the cement resists further water penetration. It is an adaptation from systems used over masonry, where water penetration is not as critical.
Any waterproofing over timber framing must be reliable because any fine cracks or broken seals will admit water to the timber and the rot will not be noticeable until it is well advanced. The substrate for the waterproofing must be as rigid as possible to resist any movement in the flexible timber framing.
Some plasterboard or drywall products are oil-impregnated to resist water penetration. These are not waterproof, and are a backup rather than a waterproofing system.
Some waterproofing systems cannot be used over walls that have a vapour barrier. Check with the supplier.
Should you drywall a ceiling or a wall first?

How do you take off sticky residue without damaging drywall?
Try using a product known as "Goo Gone". It can remove the residue left by tape and various other sticky, greasy, and oily inconveniences. You will find it in most hardware stores such as Lowe's and Home Depot, and it can probably also be found in the cleaning supplies aisle of most grocery stores. Check out the website link below.
Why do you find cracks in the drywall above door frames?
if it's an older home it is probably just settling, although it could also be something serious such as door header size being too small. if the cracks are serious i would consult a contractor about it.
Trim around a window just as a door is meant to cover the gap between the window frame and the wall material.
Usually trim is 2 to 3 inches wide so it should cover the bad drywall job fine.
Cut the trim at 45 degree angles at the top and terminate it at the sill. The small or thin side of the trim will overlap the window frame but not extend into the window area ( flush ), the thicker side will cover the space and should nail into the same wall studs as the window frame.
when you hang drywall, you have to tape off the seams with paper tape and "mud", then "float" the mud smooth.
the drywall float is a flat metal tool on a handle that you drag across the mud to smooth it out, like when you smooth out the icing on a cake

Did gunnite contain asbestos in 1964?
It's hard to say for certain, but most of the research that I've done indicates that gunite probably did contain asbestos in 1964, since it was used for internal insulation in many places (ships, shipyards, factories, etc.) until the mid-70s.

How do you know how far apart to put your trusses?
Most truss systems are spaced 24 inches on center. Depending on the length, or load applied they will sometimes need to be spaced 16 inches on center. Trussed Rafters as advised by TRADA are now spaced at 600mm c/c.

How do you resurface damaged dry wall?
What I usually do is to first cut off any loose paper or dry wall that is there. Then I spread joint compound or spackle (depends on the size of the damage) over the damaged area. After the area is completely dry then sand the area with sandpaper and make sure the patch is flush with the surrounding area. If not keep filling in and sanding until it is. Then I usually use a textured roller with paint to blend the area with the rest of the wall. I hope this helps you.
How far apart should you place your herbs?
It depends on the plant and what you want to accomplish with them. "Herbs" can mean little bitty ground-covers like thyme or great big hedge-size plants like lavender and rosemary. Are these herbs hardy in your area? If an herb isn't going to overwinter in your area, there's no real harm in crowding them in a bed to get a fuller look. On the other hand, if you're making a hedge out of plants that are hardy, you'll want to plant them according to the growers recommendation because eventually those plants will get so large that they'll fill in the gaps naturally. Long story short, there's no one answer to this question. For best results, talk to a nursery owner in your area.
What is the patching compound used to repair drywall?
Plaster will do the trick. I always buy the one that is ready-mixed.
