How do I Plasterboard Walls?

Question

I have some questions regarding plasterboarding, hope you can help:

1) Is plasterboard joining tape for use with square edge plasterboard and tapered plasterboard or just tapered edge?

2) Is it to stop cracks appearing between sheets of plasterboard?

3) Do I have to plaster over this tape or use some type of filler? If so, what?

4) Do I use beading for corners or can I use tape? Does this need to be plastered over or can I use some time of filler?

5) I've also been told that the two sheets of plasterboard would meet to make a corner and the beading would go on top of this to make it strong and perfectly straight. However, this would obviously need to be plastered or filled, put wouldn't that make the corner slope out cause of the plaster that would need to be added to cover the beading??? Surely the plasterboard wouldn't be flat anymore cause of the plaster on the corner edges?

Any help appreciated!

Thanks

Answer 1

1- Tape is for tapered edge boards.

2- Yes

3- Bet to use Quickset or similar with a wide taping blade,

4-Tape on inside corners, THIN metal corner bead or Flextape on outsides.
same filler.

5- If you have a cut at a corner and its not a tapered edge, once you fill with a wide blade you will hardly detect the thickness of the tape. 1mm

Use nylon self adhesive scrim tape.

Flat edge or non taper Sheetrock is very common, but used mostly for Fire Wall protection. I can be easily Taped also, its just treated like a Butt Joint- Taping is done to make the wall even, but should be final finished with Drywall Primer, Corner bead for outside Corners is the norm, but in some places, (Texas) they use tape, and they also make a Tape with metal edges, Use Drywall Mud, Taping and Texture mud, 3 coats is the norm, and the 3rd, is reduced, as a skim coat, and thinned for easy sanding,

I've never come accross Square edge, but then, I do live in France. Tapered is all I know, this relates to Q2 - Yes. Just use standard tape and jointing glue, PVA glue can be used..... Q4. Use what you like. Beading is easier, but is up to you Use the tape and jointing filler for all gaps and difficult to get to holes, after sanding and painting, you can't see it. Q5 Presuming the walls are straight and internal, you don't need two sheets. If external, get the polystyrene waterproof (depending on your needs) insulating type. Run some tape up the corner, joint it once, sand then joint again smoooth, sand gently and paint.

Answer 4

Joins between two pieces of sheetrock is taped and mudded to provide a uniform flat surface for paint.

To tape joints you put mud in the joint then lay tape into the joint, you need to run successively wider layers of mud across the joint.

If you've never finished sheetrock It looks like hell if you don't go through the finish process. It looks "unfinished".

You apply mud on the joints, nails/screw connections, and do it in 3 layers, sanding between each layer.
I've been wet finishing with a moist sponge rather then sanding.
It still takes time.

Answer 5

when plaster boarding walls or ceilings the boards should be bordered like brick joints there is on two sides sealed ends and two chalk ends the chalk ends always fix on the timber joints and the sealed end across the joint to help stop cracking when boarded you then put scrim tape on the joints you can get a selfadhisive one and on the corners or angles you need to put plaster board beading the you just need to skim the walls
