I have just done another small job using LW1 used 10mm beads , 4 to 5 mum serrated scrim coat and them second pass 3mm over the beads.
Again it was 15 hours later when I put the I bar over it, temp was around 6 .
The material mixed well and I thought it was easy to apply.
This was applied to EPS.
K Rend LW1 .
Small area 5m2. Applied over EPS.
Materials mixed well and consistent and very light.
Allowed material to set for 5 minutes and remixed for 5 mins.
Laid on 6mm and used 4 foot serrated Darby .
Laid in a scrim.
Allowed first pass to pick up (maybe 1hour).
The mixed reviews you read are mostly down to poor application rather than the materials .
I have been using K Rend for years and never had a problem and I have used Weber , Sto and other renders and never had a problem.
Choose a render and then choose a good applicator , look at...
If you are using K Rend the spec says you can spray both coats , I guess it depends on the amount of area you are spraying and how you manage it.
You could spray the brick face coat onto the mortar coat and flatten with a speedskim rule or similar.Dont mess about with the brick face coat too...
Hello Harry I have been using K Rend for years , HP12 HP14 with mesh and TC15 acrylics and silicone.
I have also done miles of Render Only using the standard base coat and fibre coat never had a problem.
I have used there dashing mortars and brick render mortars with great ease
I have been...
Ok so you have a Weber spec , K Rend would be the same using HP12 render mesh and 3mm over the mesh and finish with TC15 and you can use that over the masonary areas if you use R7 acrylic .
You don’t have to paint the TC15 just pick a colour
Omoeko,we need a bit more info.
Is this an EWI enquiry or Render only.
What sheathing /carrier board will you be using over the timber frame ie plywood or a Cement particle board to install insulation or a render only board.
It’s the new lightweight scratch render used it a couple of times .
Can be used on Insulation and masonry with mesh applied between 2 / 9mm coats .
Scratched back to 15mm beads
Laid it on in the afternoon and scratch it of in the morning.
Also can be dashed
Hand applied or spray
It’s a good starting point , Cembrit Knauf & Euroform are popular and are always updating materials.
Remember these are for Render only ,if you are fixing insulation a different type of carrier board should be used but the company’s named can provide details .
Here is a BBA certificate that states you can use Hp12 and TC15 over a CP board but it does not specify which CP board .
If you look in their literature there is a lot of info that will assist you when you are specifying jobs .HP14 can also be used .
Watch countryfile on a Sunday ,watch the weather on the BBC on Sunday night,Monday morning before I go to work,Monday night Tuesday morning etc etc even my granddaughter calls me when the weather is on .
Hello, is the house private or on a council estate and where is it .if it is social housing the house type will be listed and the local council or the Bre report will be able to identify the house type and what materials were used to construct it.
K Rend FT has not been assessed to be used over a timber framed structure you would be better advised to use HP12 or HP14 with silicone TC15.
K Rend will also provide you with a list of render boards that you can render onto.
Hello,boarding over the existing could possibly be an option, would save a bit of time and mess rather than hacking it off.
You could use a thin EPS or phenolic foam board if you are not concerned about the thermal value and scrim and dash it or texture.
Markla the KRend TC15 is tinted in Northern Ireland,did you buy it direct from them or through a builders merchant.
Did your customer pick the colour of a sample card , you can get a 5kg sample tub from KRend and make a sample before you buy the materials.
Hello , is there a specification.
Have pull out tests been done to confirm that the fixing you are using is sufficient .
Which system are you using they would specify how they would install boards to a soffit
The 120mm could be specified to reach a certain u value target on a particular construction.
Building regs say that the target should be .3 it's a different target in Scotland and some housing associations request .28 or lower even.
To achieve this target the type of fixing and how many...
Baumit and Parex do an additive but there is a lot of ammonia in them so be careful mixing and disposal of materials,they would have to write it into their spec which would then allow you to use it,they can also change the colour of the texture so if your doing a a street of houses you would...
