Hi Gents,

I am a customer who is looking at the best solution for me....

I have an area of 40m2 that was originally pebble dash render. It has now been knocked off back to brick.
It has left an uneven surface and also pulled fair amounts of mortar out of joints, some brick faces are also pulled off slightly.

The question is what is the best solution? Do I (proper tradesman is doing job but offered various solutions!)
1. Use fungicidal treatment on bricks, then prime it with R7
2. Do i use fungicidal treatment on bricks and use SC scratch coat to get rid of uneveness
3. After Fungicidal treat do I use R7 then basecoat H12 with Polymesh then Silicon FT
4. Or R7 SC scratch, mesh, H12 then Silicon RT

I have rung both Weber aand K Rend Tech lines (K rend seem much more knowledgable) and Weber keep saying we cant guarantee our system on your substrate?

Any advice please
Cheers
Dave
 
what are those guarantees worth anyway? has anyone on here known the manufacturers to rectify when the jobs fail?
 
No, I have read that on many posts and replies, suppose I just want a bit of security and not go to the big outlay to get back to quare one with a crap product.

I can only go on your recommendations as i don#t use the gear and the tradesman has used both K Rend and Weber Pral M and says he hasn't had problems BUT Weber Tech say doing it with SC Scratch will cause problems or is that a con to get you to buy their base coats aswell?

I just hope some of you guys can give me a bit of expert advice to put my mind at rest and make sure the person that does it has the best chance of doing it right and doing it to last
 
Cheers, so you reckon SC scratch with mesh embedded then backing coat H12 plus top coat of Silicon FT??

Thanks for your help

maybe they wont gurantee it because youve proposed to go over it on sand and cement as a base.
to be honest id be doing it with a parex system, but your going to get different feedback from different renderers, depending what product they use on a regular basis.
ive used most different pre bagged renders about and found parex to be at the top for usability and technical specifications.
they will both be knowledgeable including weber as there part of one of the biggest groups in the world, whether you got through to a numpty.
The only way they would guarantee it if you were to use all of there products as part of there system as a whole, granted more costly but for 40 metres its not a massive area.
id be using some sort of alkaline mesh incorporated in your base coat, as its only a minor additional cost
k rend r7 is just there primer, whether you would need r 7 and there hp12 is questionable or are they saying to add the two together as a diluter?
 
We have several options that can be used for this project. Feel free to give me a call on 07807495304 i can then gauge what materials would be needed for this substrate.

PS. Thanks for the comments Owls
