Hi, applied my base coat today with mesh coat and then topped it all of with a final coat of base coat 5mm total and it bounced it down, full scale downpour!
( weather forecast was predicting dry all day !! )

It made it very difficult to trowel up and has left very faint trowel/ spatula lines.
Will a 1.5mm silicone topcoat cover that or is their any other little tricks before I use the primer in 5 days time.

Thanks in advance, first ewi job on my own and it's a mates property, so trying to make it look mint.
 
1st coat 3-5mm, buttercoat 2-3mm max..depending on the system used.

Your second coat is way to thick and liable to crack now at that depth...its call thin coat render for a reason...your depth on the wall should be on the 1st coat if any where, with the mesh towards the outer layer of the render

thats a sleepless night then and its his mates house!
 
Sorry you mis understood my original post. It's 5mm in total, 3mm and 2mm butter coat but the butter coat got saturated and then made it difficult to remove the odd trowel lines.
I'll try and post a pic !!

Sorry alpine but there not faint trowel lines !well maybe from the next street lol!am sure one of lads on here can advise you failing that your mate wont be happy !good luck
 
To be honest I've only ever done a couple of ewi's as part of a gang and mainly did the top silicone top coat.
The friend of mine initially wanted render and tyrolean finish but then changed his mind at the last min to have eps ewi with 1.5mm silicone finish.
I didn't want to take on the job but had forced on to me !!
It's the top half of his property and both the back and front are nice and flat using my spat, the side elevation got absolutely soaked and I couldn't trowel up as the picture shows!!
I,m just after any tips or tricks for what I can do next with the gable?? I have 2 bags of base coat left but don't really want to add any more weight ect.

Can I removed the high spots anyway?
I have all the time in the world with it, so i don't need a rush solution.

thanks in advance
 
Do they work rub down the high spots and lines??
I'm not bothered if it takes me a week of rubbing down. I just want it to look right even though I'm not that experienced with EWI. Your only as good as your last job is my motto.

I've been a spread for 16 years and I've always just stuck to what I know and not bothered with jobs I know little about, but as said earlier I was forced into doing this ( on mates rates as well ) and just the gable looks shocking in my opinion due to the torrential downpour.

Thanks for your help with this matter.
 
Well cheers for helpful advice!! But when he has borrowed the money to afford the extra for ewi and I'm doing 80m2 for £400 labour to help him owt, ripping it off ain't an option!!
Found a few samples of other's basecoat's. Are these bad examples??

You can shave those lines off after it has first set but still a tad green. Just use a flexi or summit.

Those pics there. The second one looks bad you can see the board squares. You will see that in the sun eve after texture.
 
No need to worry about putting some extra weight on the system! You haven't applied the right thickness of base coat anyway! The best move in your case is to apply thin coat of the base coat adhesive over the silicon top coat,wait till is dry and then apply the silicon top coat. If you try to apply the top coat over existing top coat ist a nightmare ! The surface is grainy ,not smooth, and is twice hard work to achieve some good quality. And there is a reason for the size of the grains in the top coat-it's telling you how thick you have to apply it! 1mm for 1mm thickness , 1.5 for 1.5mm thickness .......
hope this helps

If that's the case, this is too thin! Total system make up to most BBA thin coat systems are 7-10mm!

Browsing with a tablet its a pain keeps clicking on links like & dislike...sorry mate nothing wrong with ur post me being a donut
 
Tell me about it! And if you have bulky fingers you can express your self in a way you have never expected:RpS_biggrin:. And then people are calling you with names only your mother had when you was young:RpS_biggrin:.No worries mate!:-)
 
Listen to daddy brown.

Use a stone or the toe of an old trowel to get rid of the worst lines and then mix yourself a wet slurry mix of basecoat and apply to the wall as tight as you can putting more pressure on the heel of the trowel so you are leaving no lines.
Any lines you have left just go back the next day and remove with an old trowel.

It'll be fine mate.
