Sand and cement question

[2985mark]

What's the best way to sand and cement on a internal wall and and ratio and could you tell me what else you put in with it. As all people are diff envy and want to find the best way thanks

 

[gooner59]

stick fairy washing -up liquid in the mix and it will float -up the walls ......

 

[2985mark]

Thanks for that. Is it the same when you do a dpc or do you put a waterproofer in it

Keeps yer hands soft as well :RpS_thumbup:

Ha

 

[carlos]

Depends on background, and why your using render.

If after DPC you will need to follow the installers spec or you could lose any warranty offered.

 

[2985mark]

Ye it says to use a waterproofer in both coats Do you use 4.1

 

[carlos]

DPC firms usually have a spec to follow something like

reinstate wall plaster using 3-1 salt free washed sharp sand to BS XXXX and cement, containing OUR waterproof additive blah blah blah.

 

[carlos]

The amount of waterproofer will depend on with one you are using. It will normally say on the container.

The amount will be either a ratio of waterproofer to water. So many ml to a litre of water.

Or waterproofer to cement, so many ml to a kg of cement.

Ye seen all that shite they put on ha. Thanks for the comments

 

[carlos]

Normally we use 3-1 s+c and skim with board when cured, but this does alter from time to time.

stardrops are better than fairy liquid by a mile, and also its advisable to urinate in the mixing water at this time of year to stop keens developing, get the labourer to riddle the sand to 0.02 grain size, before adding the dry hydrated lime,

 

[beader]

Don't forget to add some cat **** to the mix .:RpS_thumbup:

 

[beader]

Don't forget to add some cat sh1t to the mix.:RpS_thumbup:

 

[gooner59]

it's the rules the more cat's you want in it the longer you leave the sand out uncovered, lol

3-1 what a load of shite who thought that up , Hmm I know in times past when lime was used for rendering. One of lime to 3 parts sand to fill the voids in the mix, and so they think this is also correct today useing cement.

 

[carlos]

Why is rendering using a 3-1 mix aload of ****?????

 

[henry]

well why would you use a strong 3-1 mix on internal walls ? for what reason.

 

[carlos]

If the makers on the additives you are required to use spec it thats that surely????

 

[Render Systems]

5 to 1 maximum on soft brick for a scratch and 6 to 1 level coat...

 

[carlos]

How do you grade the hardness of the bricks????

 

[Rhys]

Use whatever it says in the specs, no comeback then.
Usually use 5.1 and Sika MaxMix additive.

 

[Rhys]

Cow slurry is a good additive as well, local farmyards are a good source. One bucket of slurry to one bag of cement. Definitely good sh*t :RpS_thumbup:

A handfull of gravel slows it down.
