Weber rendaid

[dai dog]

Hi guys, render technical state they're rend aid, goes about 7.5 m2 @ 2-3 mm thick.
Has anyone got experience of it going over brick & black mortar joints? If so, in you're experience, how far will a bag go? (The walls hacked off aren't the worst, nor the best!) regards Rhys.

About that I always prime the wall first with sbr @4-1 just to help it along that stuff is quite chewy then troll on tight then stipple

You will probs get 3-4 mtrs a bag over old brick

I was finding about 3 to 4 m a bag on brick so asumed I was putting it on too thick I endedd up putting on a bit like acrylic thin coat "lay on scpape off" and and that gave me about 6m2 per bag, when pointed flush you get around 7 same as block work @madmonks info could be useful never tried this.

I get about 2.5m2 a bag but that is about 3-4mm thick, fully meshed and scratched.

The only time i got cracking is when i meshed in the rendaid ,never done it since ,always mesh in the mono now ,i think in the rendaid is to close to the substrate ,not saying right or wrong ,just a thought

you can put it on tight ,then take a roller to it ,that does get more out of the bag ,and let the rendaid give a very good key [video=youtube_share;hRlo7YWsbyE]http://youtu.be/hRlo7YWsbyE[/video]

Weber told me not to mesh the rend aid either although that was from Felix the Caribean cat. Makes sense but since I have meshed the pre rend never had a crack.

I dont like meshing mono as I am dubious about the top coat being sat on a sheet of plastic. Maybe if the mesh was 5-6mm but the 4mm is a bit small for me. I have got quite a variety of meshes from 4mm to 8mm.

we all have to go with what works best for us all ,weber guys read from the book ,we work out in the field day in day out ,they are always moving the goal post mate ,as you know

Over the rendaid i spray about 10mm first place and then mesh ,we bed the whole mesh in the first coat until you see no mesh ,then top coat ,so it does not sit on the mesh ,it is embedded in it ,if you know what i mean

Same, put on tight then stipple with a roller, make sure you roller when its wet.:RpS_thumbup:

mesh as further away from the substrate as possible what ever render you use.

not teaching you how to suck eggs or owt :RpS_laugh:

 

[owls]

bit of an onion theres more strength in mono if the outer layers meshed less chance of movement resulting in any cracking.

The problem with stipple is the peaks can come to the surface and you have to flatten the peaks where mesh is going to go or there is a risk of the mesh coming to the surface.

Agreed, you do have to be careful for that not to happen, you do have to scrape down the odd area when dry.
