so on this one and we want to show we finish sand and cement render on the
previous videos I showed how to mix sand cement render how to scratch coat how to
coat up your your final coat and how to straighten it so if you want to see them I'll drop
links in description and I'll also can put them all on playlist I'll put that
in the description also but so basically what I've done here I've start started
at the top coated it all on and I've got it straightened then I have went to the
bottom I coated it along the joint got it straighten then coated the whole
wall and straighten it all up and so then obviously it should be setting
from the top down basically roughly from where you coat it first it should be
tightening up there and going down to here where the stuff hasn't been on as long
also the moisture from the top will be dropping down in the wall as moisture
would tend to fall other than climb so that's something to think about as well
when you get more towards the bottom as the bottom will be possibly at least the
last sort of block and a half will be a bit wetter but i will show you the way I
pull it in so you can see I'm actually pressing with decent bit of
force at the top here as obviously the top will have picked up it's been on
longer and on first like I said in the previous video the way I've left the
render open just a help let it dry that but more so you get onto it and rub up so
all them holes guys is they're all when its rubbing and you see the
gritty sorta marks or any divots any dents or trowel marks or or marks
from the straightedge you gotta get them filled in so you'll always want to have
that a little bit of mix leftover even to be half bucket so should get you
off a wall this size so what you'll do is I just usually use it off the trowel as you
can see and just just pick up we bits as a need with the float and place them in
the holes any misses and then float smoothing you at this stage as well if
you do feel anything that's bumped out too far you make one I just check it
again with your straight edge just to be safe but you can see here as there was
quite a bit of a hole there and you can see how just add a little bit just
helps fill it in and smooth them out but on the most straighter you get your wall
previous this stage this is the finishing stage so you do want to take
your time as the straighter you get the wall the quicker this stage will go but you
don't want to be tear and tearing your wall till there's nothing left all you still
have to leave a good good coat on the walls well otherwise you will have
straighten it back to the scratch coat but again that's that's all in the
previous video there i'm finding it be a bit tricky here at the top of the
soffit it's quite a hate soffit and just about get the float in and i could just a
about get the trowel and stuff into it as well but for the likes of them details you'd
want to spend time on them and there are the Bits that do count up around
soffits down the angles and you know that they they still count people will
still look at them need to make sure their nice and finished and
clean down afterwards and you can see I'm actually up on
trestles here just to get the top off so once you get your top all rubbed up the
next stage will be the sponging so I recommend that if you're doing something
with a split level such as this wall or a big long wall bit of area I do
recommend that you try when you float it up you do try and finish it as you go
especially when you're up on trestles as you can see I'm finished it
off now but it will save you a bit of time jumping up and down off the
tressels and basically you'll have to pull them back and forward and climb up
you risk getting dirt on the wall from the tressels doing it that often or
taking a chunk out of the wall with the planks or with the tressels so I
definitely recommend trying to get it sponged to try and get the whole top
we're here at the high area or the first where you'll get it done and dusted out
of the way so again and keep your sponge clean as you're gone and you do wanna
have a big pile of water in it and but a moist sponge to me is the nicest helps
you finish of, it is quite warm here and it's a bit overcast and cloudy
there but to me that's not as the perfect conditions because you don't
want the sun beating off it and when you're trying to get it finished be a
better bit trickier in my opinion to get it done when it's just drying to
quick to me you'd keep cloudy days is the best way and you can see and the way
I'm finishing off after it's all floated up with the plastic float just basically
I'm sponging in underneath the soffit up there im going sort of long ways with
it and then if I didn't drop the sponge what I am doing is just just
sort of going up and down long enough strokes guys you can if there is a
couple of a divot you can work it in with the sponge slightly as well will tidy it up nicely don't forget the
eye ball it left right up down especially before you take away your your trestles
there so back down into the bottom again you
can see it is a bit wetter as you might Find this when you're starting to rub up
and that you starting to catch up with it a bit and that's that's actually a
good thing if you find that you're going too fast finishing you can you know you
can grab yourself a cup of tea or clean up tools and stuff as you may not want to
rub it too early I don't mind rubbing it when it's wet but don't likerubbing it when
it's too wet my mix here has sbr and so it does
tend to be a bit stickier and so when it's wet that really does be sticky to
the float but I tend to like it you know there's a stage of
rubbing it when it's wet and it's just sort of tightening and this
stage I like to catch it and I don't like rub it when it's too hard either that
that's actually a lot more hard work and with this one when you rub the bit so
it's a bit softer you have to be a bit more patient and don't apply too much
pressure you might find its a bit more difficult at the start but as you pick
it up as you learn more you will you'll get you'll get into the rhythm of it
and again we're I'm Rubbing here from is left to right and the reason being I
started that side so I'm still following the fresh coat around won't from you all
the oldest stuff to the new stuff and just showing is here it's talked about it
earlier the bottom tends to be a lot wetter and don't be afraid if you rub it
up and if you know what I'm saying is when it's wet you don't want to you
don't want to work holes into the render though you don't want a dig in too much
with a float and you don't want to leave too many lines so
if you feel that that's happened let it sit you know 10 minute come over touch
with your fingers press it press it and get a feel for it give it a me Rub the
float and is it to wet give it another five minutes you know
it's a time in game plastering all timing preparation and timing and get
your mixes right and that's definitely what the game is all about
and with rendering here sand and cement render
the bottom will always be a wetter you have moisture from the
ground but you've also like I said the moisture of the walls travelling down
the way just follow its natural path but if you have rubbed it and you you know it
is Rubbing in smooth and you know you're not dis shaping it still staying
straight and but you still see they odd line what you can do is you
can actually rub it all again don't be afraid to give it another pass and
there's nothing wrong with Rubbing the same wall twice there's a you know as
long as it's staying in shape you're not pulling it outa shape you can always give it a
second pass and then sponge it up but so basically I think I've covered
everything for now and I'll do a quick recap here and go through all the stages
from the very start and that'll be in a playlist below as well
particular render was the three to one scratch coat
how to to prepare the block walls clean off preferably with the
floor scrapper clean off all lumps and then obviously get it soaked down if
it's an older wall whenever it is if it needs a splash maybe do test but
getting thinking about the suction and controlling your suction
so after that then obviously i showed you is how to give it the undercoat a
scratch coat render there and then I showed you previously how to coat the
render this coat is 4 to 1 sand and cement again how to coated it so first
things first you gotta get it all on as neat as possible and make your life
easier when you're straightening up so the next stage after you get it coated
is getting it all straightened up taking out any humps and bumps and making sure
you fill any slacks and then after you have the wall straight down the only
things they have to do is the final touch which is running up with a float
and give them a little finish off with the sponge and I find the car sponges
work grand but there is obviously also rendering sponges magic
sponges so hope is enjoy these videos guys subscribe for more hit the like
