Kitchen -- wash nasty wall and windowsills, and repaint
Kitchen -- wash nasty wall and windowsills, and repaint
unit 24 -- plug/fill hole in front door where camera was
hoover/clean loo floors -- this will give good impression to landlord for very little work.
outside -- make sure our balconies are clear when we're done
tidy everything up inside, remove rubbish -- junk left behind will probably be removed by landlord at our expense
unit 24 -- remove doorbot and patch hole with wood, then fill edges with wood filler (brown stuff). This should be done as late as possible, but you can make the wood patch by taking doorbot out temporarily, and only put it in as the last step.

how to split breeze blocks

For irregular / thin shapes, use the big saw with the red handle, as it's already dull. Most splitting, however, can be done with the cold chisel and hammer. First,carefully go around the entire block along the line where you want it to split, only chiseling 1-2mm deep. Then keep going deeper each time and eventually it will break, leaving a nice rough surface for the mortar to stick to.

how to prepare for laying breeze blocks

  • Plan out the sizes, including mortar space, and split the blocks ahead of time. You don't want to be stuck with rapidly drying mortar and no blocks to lay.
  • Put down drop cloths/plastic sheet on either side, so the mortar doesn't go everywhere.
  • It may be worth trying to make a frame out of a sheet of wood and some planks to ensure levelness on one side, so you can place the blocks against it. Don't forget to go back and fill in the gaps in the mortar joints before it all dries. This would really help with the divider wall.

how to mix mortar for laying breeze blocks

  • WAIT! Get everything else ready first, so you have the maximum amount of time to work with it.
  • Wear gloves and a dust mask. Cement is really irritating to skin and lungs.
  • Use the white dish to measure out 1 part cement, 4 parts sand onto the large plywood sheet. Mix a little bit while dry.
  • Clean the grey bucket, and fill it part way with water. Mix in about 1/4 - 1/5 of a sachet of plasticizer.
  • Make a hole in the center of the cement/sand mix (volcano!) and pour in the water a bit at a time, folding it over, and using the saw flipped over to pull/chop it. You'll probably need to refill the grey bucket again before it's smooth enough.
  • When you can make an indentation that will hold its shape, but it is wet enough to slip off the trowel easily, then it is ready.
  • You can keep mortar covered in plastic so it will take longer to set.
  • Once the mortar starts to become difficult to work with, don't add more water, it should be thrown away.
  • Clean the shovel, and scrape off the board!

how to lay breeze blocks

  • BE CAREFUL! Take your time, and use the level to make sure everything is straight. You can't go back and fix it if it's crooked. It's harder than you'd think.
  • Lay a line of flat mortar, making sure that it is thick at the edges of the blocks, not just in the center.
  • Put lots of mortar on one side of the brick to be laid, just like the last step.
  • Carefully place the brick, keeping it in line with the rest of the wall. It must be vertically and horizontally level, as well as not twisted or offset. The most important thing is that it is not sticking out of the wall on either side or tilting side to side. To adjust, you can tap the top of the block with the butt of a hammer or the trowel.
  • Fill in any gaps. It's easier if you put the mortar on liberally and evenly in the first place.
  • For bricks at the top of the wall, or that have mortar on both sides, just do one side, then fill in the rest with the trowel or your fingers (WEAR GLOVES).
  • Scrape off excess mortar with the trowel or wood.
  • Scrape with the end of a bit of plastic drain pipe to make the nice rounded indentation in the mortar joints. Vertical joints first, then horizontal ones.
  • Clean everything off! mortar comes off with water, until it dries.
