You need to make a frame out of wood, put gyprock on it, then tiles on the gyprock.

Say the frame is 1700x800mm

After cutting the first length, but the second one beside it, mark the first one at the same length, and cut it - you don't need to measure it
- Make a small cut at the mark by pulling the saw backwards
- only
- , so the saw doesn't slip out of where you're cutting
- Measure twice, cut once
Get the width of the wood (~45mm), mark that long from the end, divide into 4 even squares, then mark with X's half-way to the sides of the beam - this is so you can put screws in at the X's
Pilot drill holes for screws so they're easier to screw in - drill them all the way in
Then use a countersink to make an indent so the screw is flush with the wood
Put the short beam at the end of the long one, lined up with the screw holes
Screw in 4 3-inch screws
- Do it a little bit at a time, don't push too much
- Push a little bit on the end of the drill to get the screw in
- Make sure the drill's the same orientation as the screw
- You can make the drill go into reverse to get the screw out, and try again
- The drill bit should be slightly bigger than the screw if it's gripping, smaller otherwise
- Sometimes you need to make the drill longer if the screw doesn't go the whole way through the wood
Screw in both short beams to one of the long beams first
You'll need a middle beam, ~800mm long
Mark 600mm down - where the bottom of the middle bit goes
Mark 4 squares above the 600mm line, like before

It has a tapered edge, so when you join 2 pieces together, it looks like 1 continuous piece

Cut at 1200mm with a stanley knife - it's easier if you cut against a long beam
- Pull the knife against the beam so it doesn't slip the wrong direction
Cut that piece at 600mm
Cut that piece at 890mm - the width of the frame + 2 * the width of the beam
Drywall screws are a bit smaller than normal ones
Screw in in the corners and middle, a bit, so that the screws are stuck in the gyprock
Put the frame in a vice, screw gyprock in - make sure the screw heads are past the gyprock, it needs to be flat
Put more screws in until it's secure

Put the closed end against the gyprock, make sure it's not against the frame
Draw a box round it tightly
Hammer a hole in the center of the box, then paddle saw from the hole to the corners, then round the rectangle - it's better to stay inside the lines, you can sand off extra bits, but you can't get pieces you've removed back
Rasp edges if you need to
Push the yellow sides of the box in, push the box in, then pull the yellow bits back, so they're behind the gyprock

Mark a box round the hole, like with the socket box - use a spirit level
Cut with a paddle saw and rasp, like before
Cut another piece of gyprock that's the same size as the hole - it should be slightly bigger, you can rasp it
Cut a length of wood a bit longer than the hole
Put drywall screws on each side of the hole like before
Put the wood behind the hole, then screw the screws in
Push the extra piece in the hole, screw more screws into the wood
You won't see the repair once it's filled in and sanded properly

You need a strap of wood at the bottom for the tiles to sit on
Cut it, put screws in the wood a bit - make sure they'll go into the wood & won't hit the screws you've already put in the frame
Screw in against the gyprock, make sure the wood's level
Measure a tile to work out the gauge, and mark the lengths against a gauge rod (can be just another beam)
'Tile' the tiles (like a desktop background) against the gyprock, leaving 2mm between them for spacers
If the tiles leave a big bit on one side not covered (a cut), find the middle of the wall and tile from the inside out, so you'll leave an even cut on each side (if you're tiling a floor, imagine it's a square)
Run silicon round the corners of walls - you don't need the anti-mold one, it doesn't work
Use flexible adhesive on wooden floors - joints will crack with movement on the floor otherwise
use ordinary adhesive on walls
use waterproof adhesive in a kitchen/bathroom
powdered adhesive's better for grout
When putting a bath in, seal it first, half-fill the bath with water, and let it sit for a day, then tile
Double seal to stop leaks

Put adhesive on the wall or the tile - hard to do it on brick walls, tiles are easier
Push tiles hard against the adhesive, aligned with the lines you drew earlier
Put spacers between 2 tiles
If a tile's below another one, put a spacer between them
use 5mm spacers in bathrooms so you get grout in the gaps properly
Wipe every 3 or 4 tiles with a wet sponge
Squeeze tiles flat so they're against a flat surface - check with a spirit level
Bob Marley died in 1981
Wash the adhesive trowel with a wet sponge, not in the sink - it'll dry out and clog the sink - then throw the water in the bin
Make sure there's on adhesive around the tiles - you won't be able to put another tile ontop/beside it; you can chisel off the adhesive

Draw lines on the tiles where you want to cut them - you can draw on the back if you can't see lines on the front

Drill holes before grouting the tiles - drill dust will break the grout otherwise
Let the tiles settle for a week after drilling before grouting them
make sure to clean them
speed plug cavity wall anchors are alternatives to wall plugs
if putting a TV on drywall, cut out some gyprock, find out where the wall studs are, put a horizontal strip of woof on the studs & replace the gyprock with MDF - the TV definitely won't come off the wall now

draw a circle in one of the screw holes
with a spirit level, draw a line across so you know where to draw the 2nd circle & draw the 2nd one
very gently, with a tungsten tipped bit (looks like an arrowhead), drill a hole - press gently against the tile 1st, don't go the whle way through, you'll think it's not doing anything
go the whole way through with a normal drill bit - you might need to go through more with the tungsten bit
put wall plugs in the holes - unless the hole is in the wood the whole way through, no need for them then
gently hammer the plugs in if they're tight
put screws in the TL holder & that in the drilled holes, turn by hand a bit so it catches, screw in with a drill, in intermittant bursts

cut the top off with a stanley knife
squeeze the trigger until a bit comes out
run along the tile edges
lock the trigger so silicon stops
clean the extra stuff with a wet finger
can take it off later with a razor or masking tape - leave to set for 24 hours & peel off

get a rubber grout float
clean the tiles 1st
take holders & spacers off
put grout in the spaces between tiles, not on the tiles themselves - it's awkward to clean off
do a few tiles (2 or 3) then clean off the extra with a wet sponge - it hardens quickly
make sure the grout's properly in the gaps
wait for a while, it'll turn dusty, then clean again
clean 24 hours later again
coat gyprock with PVA to protect it from water
