leaking pipe, damp wall

[lufcluke]

just a quick one,
a pipe was leaking under the house which has now been fixed and damp had started above the skirting. i have hacked off all the plaster back to the brick about 300mm above the damp areas. the question is once the brick has dried out, what if anything do i treat it with and which backing plaster would be suitable?


any help would be appreciated, cheers

British Gypsun Dri Coat would be good as a backing coat

usrd 2 b a brittish gypsum renovating plaster for plastering damp walls havent seen it for a while tho

 

[beddy]

Dri coat is a gypsum plaster designed for damp proof work. Can't beat s/c in my opinion

 

[henry]

Dri coat, Render lite are superior backing coat plasters to sand cement me thinks. Sand and cement is just cheaper way of doing it .

 

[steve1903]

i thought dri coat was only used along with a damp proofing systim tho

 

[warriorupnorth]

As henry says' dri coat, limelite, renderlite, but if you want to do it on the cheap then sand cement, but the genearal consensus on refurbishment of older properties is to us a breathable material like the lightweight backing plasters mentioned or lime renders

i would go with what henry and warrior said


sand and cement ok on this but using dricoat saves getting sand/cement ,mixing ,mess and all that...

dricoat mix with a wisk and your away...

Use what you want mate there isnt a damp problem youve cured that

But bear in mind that drying times in masonry is one month per 25mm of substrate, ie 9" solid brickwork 9 months drying time and longer in some cases

 

[steve1903]

and not any kind of plaster stopes salts comming throo

 

[lufcluke]

Thats what i would have said and i would go with bg's dricoat as they recommend using multi on it rather than limelite as they prefer you use there own brand finish which takes forever to go off.

 

[martinemj]

its better skiming over dri coat with limelite high impact finish

 

[spunky]

How about letting it dry and using hardwall and skim

 

[warriorupnorth]

How about letting it dry and using hardwall and skim

I wouldn't personally

 

[bodplasterer]

its better skiming over dri coat with limelite high impact finish

But like i said martin it take forever to go off and bg recommend using multi with there product.

 

[spunky]

Yeah Martin go **** yourself biatch

 

[martinemj]

yea read the spec from bg
have used multi over it on one job ,

agree limelite can be slow drying though

 

[martinemj]

lol spunky

 

[spunky]

Sorry Martin didn't mean to use the ****** word

 

[henry]

I wonder sometimes.

before
Ive seen these figures before Paul, drying out times would depend on the time of year for instance in a long hot summer the bricks would dry out a lot quicker and another factor is the porosity of the brick and how much water it can hold and or disperse only experiance can judge that, but yeah fair comment,
