Wet dash

[JackofAll]

Getting closer to plastering stage now, will be getting a crew in but am wondering which mix is better white sand, white cement, white chip (10mm) or grey sand, cement, any 10mm chip and lime. Looking for a bright white finish. If going the 1st mix is there need for lime? I know that whichever crew we go with will most likely know but would like to know for myself, thanks.

With the first mix the lime won't make it much whiter but it may be a better consistency / easier to work with.  Can you make up sample batches?

Good idea, though would require buying a bag of each(tight git I am 🙂 )

I’ve wet dashed ours with K Dash 

Ive several pumps that spray the dash but my wife wanted it more random Like I used to do 30 years back in the Lake District White cement Silver sand 

3-1-1 

The silicone renders keep there colour better

Thirty quid for a couple of grands worth of render.

You used the white cement in the scratch coat too? What size chip did you go for Nod, it's a fine looking house.

No. This is K dash

But no You don’t need white cement or silver sand in the scratch coat

Chatting to plasterer re wet dash, he asked how many coats the were specified. My understanding is scratch coat and butter coat, the dash is then applied as the butter coat as it is going off(though not exactly sure when that is) am I wrong? He said its alot of extra expense whereas if he applies a thick scratch coat then dash onto that. Any advice? Also what is the idea of the butter coat?

Run a mile 

He’s clueless 

[JackofAll]

Got that impression, just needed confirmation, so is it correct to dash onto butter coat as it's going off?

Scratch coat If sand and cement leave for three days Then a tight coat and dash
