Hi ppl I'm new to forum and been on the trowel for about 8 years, been taking my skills outside to build some rendering muscle here and there over the last few years and got a nice scratch coat on a few weeks ago

my question is this, in the past I point blank refuse to render when the the sun is a shining, but am on a bit of a dead line here and against my better jugment am thinking of going for it and bashing on the top coat.

anyone with some serious render skill set like to throw some advice into the mix would be welcome ?
 
Welcome to the forum Skimadim.....

What type of render you talking about?

Can you put up any shading?

Bit more info and I am sure you'll get some help and comments (good and bad... LOL)
 
hi runswithscissors thx for quick reply mate , just doing basic two coat cement,lime,sand render 1:1:5 for the scratch 1:1:6 for the top and float to flat .

had a browse round forum and seen some of the good and bad lol
 
Hi Skimadim

sorry mate - S&C and Lime not really my speciality....... I'm sure you will have loads of guys along later to help.....

They are all out in the sunshine getting beered up!

Good luck
 
Try ans work in the shaded areas , follow the sun round or try n get a tarp up , then mist spray with water as it cures, good luck n welcom to the forum Dim
 
Thanx for the replies, by the sound of it this may be possible to get away with will get a tarp up and keep wetting down , if anybody tried this and failed don't be shy to let me know
 
As above, get on it first thing or early eve depending on when the sun hits the wall then float up, get paid and down the pub for a few ciders :RpS_thumbup:
 
i tend not to bother in the sun really but recently i also had a deadline to meet and had no choice so i just did exactly what warrior said and followed the sun round, still cracked though cos the builder insisted i do scratch and top straight after eachother and i mean straight after id finished scratch go back and top haha, in retrospect i should have just let the sun kill it and worked on my tannage instead
 
Always work in the shade and cover up against the sun and the breeze. If the sun is on the wall in the morning then cover it up the night before and wait until the sun has passed otherwise the wall will have absorbed the heat and the heat radiating out will rapid dry the mortar and it will go to dust! I use scaffolders debris netting. Doubled up for the sun/wind. Tarps flap too much in the wind and keep people awake.
 
well, got up early, tried to follow the sun and stay in the shade, kept misting the render and hung some wet sheets about an inch from the wall to keep it cool, all looked well when I left so i will let you guys know tomorrow .
 
Round the edges of and have a good go at the sides with a bit of sandpaper just in case, there mint mate plastic trowel might do the same it just keeps the surface from going too sandy
 
A poly float puts a rough texture on the surface, so increases the surface area to allow for air drying, something we need most of the time. That Draper float looks like it will close the surface in and therefore reduce the area being dried by [warm] air :RpS_thumbup:
 
Doesn't really bubbles you cant float a wall till it's ready it's got nothing to do with opening it up to let the air get to it that's what a straight edge does or a Darby if you don't want it too, by the time its floated it should be ready all the draper float does is pull a bit of moisture to the surface so you can sponge it
 
Dave is that the blue float? I was trying to help churchy find a larger one of them a couple of year back he said they're the nuts.
 
He told me about them I ended up sending him mine, there the balls mate it leaves it like you've sponged it even if it's gone a bit far

So you could just use the steel before sponging then? Or does that draper float bring more water to the top?
 
I sponge asap after floating depending what it's like I doubt the floats got anything to do with the setting times
 
well all went well no cracks anywhere , seems this approach works well. But if anyone is going to hang wet dust sheets close to wet render make sure the wind cant blow the sheet so it can stick to the wall . Not that I would let this happen to me :RpS_biggrin:
