hi,this is my first post so dont go to hard on me
getting a lot of enquiries about k-rend mixed feed back from some of the lads and also various application methods and i know ther are verious k rend products
we will be applying by hand if we take the jobs on my query is regarding alkali mesh is this needed with k-rend if so is it fitted in or over the base cote or introduced wile applying the top cotes
one job is red engeneering brick the others are block any usfull advise would be appreciated any other advise will be taken on board thanks, intsol
 
k rend offer this as a complementary product there is no mention in there aplication advise about alkali mesh i think it is up to whoever is doing the job to us there exsperiance on wheter the job needs it or not
i now know it is desiged to strenthen the base cote and bind the substate together so thanks for the advise
still dont think is part of general k rendering ?
 
It depends on the backing structure and how stable it is....... get in touch with K Rend for s proper spec.

Normally if you are goig to use one of K Rend's Basecoats, they will advise the use of a mesh.........
 
Use mesh in base coat and extra pads round door and window stress areas. Others are right.mesh not always needed but i always use over stress areas
 
As said, if you are using a base coat fully mesh it. In the mono coat whether 1 coat or over base coat use stress patches.

K rend is like Weber. They are not up to date with their competitors in Germany. When things go wrong they will then say you should have used mesh. Go full spec or face the consequences.

Avoid the cheap chinese mesh if you are supply and fix. It will bite you in the arse if you give a reasonable guarantee.
 
thanks for all the advise ive learnt a lot of valuble info i think rigsby is wright we will be using it on all rendering work from now on
cant belive how much cheaper k rend has come down in price since we last used it

If you are going to use a system, use what is specified....... any problems you can go back to the manufacturer

The cheaper mesh (accessories, etc), are ok if your making a wall finish to suit your own needs......

Rigsby - I suspect - is speaking from bitter experience.......
 
I dont know if K Rend supply their own mesh but Weber do and if you have a fault with cracking and they find out you have used someone else s nesh they will walk away. But for what that is worth they will end up walking away anyway. They know every get out clause going.

The Chinese mesh is alkaline treated (sprayed treatment) as the maunfacturers mesh is made in 1 factory in Germany and is alkaline proof. The Chinese stuff eventually rots. It takes a while and probably takes longer than the warranty given on your work but you need to know how to write up a bullet proof warranty if you give these silly 10 year warranty's. If you are Ltd then you can stop trading if the costs of come backs could bankrupt you but sole proprietors can be held responsible even if you have ceased trading. A big job like a site going tits up could cost you your home.

Even the cheap plastic beads have a problem built into them. They expand in the extreme cold and the render cracks around the beading. One guy down South West way did a housing site and every house failed in the cold snap from 2-3 years ago. He had to re do the lot. According to SAS technical who was subbed to Marmorit technical.

I suppose it depends what market you are in and your liabilities. Personally after the s**t Weber got me in last year it's quality stuff from now on or get someone else to do the job.

Exactly right

Krend cant "spec" mesh as such until they know what the project and substructure is so it will always be an ancillary product. some jobs may not need any mesh, some jobs with windows and doors will need mesh at the stress points and some other jobs will need a full coverage of mesh.

stay safe and always mesh stress points. TBH it takes nothing more really to fully mesh in the first pass.

mesh should be embedded within the products and always in the front final third of the render build up - so if your job is 15mm thick as most will be the mesh will be 5mm under the finished surface with 10mm behind the mesh against the wall.

This is standard of all rendering work so no need to cross reference manufacturers websites.
 
i must admit i find it a bit mad to think each manufacture has a different way , they should get together as an EWI industry and standardise IT ffs
