Right guys so i am putting expiation joints on here ( control joints )
try and Minimise cracking
and hopefully try and stop them all together
i will show you how to fit them
so you can nail them on but i like to stick them
so i am going to bed mine in
tapping bead in
tapping second bead in
you are going to want to plumb them up and make sure the are level
both ways
plumb that road to
once you have them in
trowel off all the excess
make sure you still have enough room for another coat
just like the rest of the wall scratch it ( key it )
like so
so just completed the scratch coating the wall and we have chosen to put an expansion
joint at either end of the wall so that the wall is broke up into 4 sections
so we put one to the far right and one to the far left
so it keeps it even looking
it looks well
and also breaks up the wall
expansion joints can also be called (known as ) control joints
as the fact is you are trying to control the cracks
the expansion joint then becomes a crack
and allows some movement if there is any movement
the wall will be back filled
it will have weight on the wall and mortise
i will be giving that one coat to try and protract it from moisture to stop it penetrating
right though to the from side
that is how to fit expansion joints
not 100% needed but it will keep the wall looking good for longer
