Primer G for any gypsum product, Keraflex maxi do'es 3-15mm bed bucket life is 8 hours though, May not be quick enough for you

any comments on the 7mm thickness ive never noticed that before,now im certain that we have all used this with plenty more than 7mm.

SBR Bonding/Admix agent - (Everbuild)

(Do not be tempted to use cheaper PVA which moisture breaks down)

SBR Bond is a latex based - Highly suited for priming areas before tiling

Water resistant bonding/priming agent and admixture for use in areas subject to humidity, dampness and continuous water contact

Improves water resistance of cement mixtures by forming a reinforcing polymer that increases long term durability and flexibility of the mix on renderings and floor screeds adhesive etc.

Can be diluted up to 3:1 with water - follow instuction on bottle


Size: 5 litre


Price: £11.99 £13.79 Including VAT at 15%

... the data sheet Broken Link Removed
any comments on the 7mm thickness ...

Haven´t found that, can you please say in detail where it is?

Acc. to the a.m. link I found on the data sheet: "Applying the mix: Apply Keraquick to the substrate with a notched trowel to a max of 10 mm thick"

Thanx 4 answering, Martin

Ultrarapid-setting flexible (S1) cement based powder adhesive for ceramic tiles (thicknesses of adhesive up to 7 mm).
Applications:
Interior and exterior bonding of all types of ceramic floor and wall tiles (double fired tiles, single fired, porcelain tiles etc) on:
– old floors and walls (ceramic tiles, natural stone, terrazzo, concrete) provided they are solid and clean;
– cast concrete, properly cured prefabricated concrete panels (at least 4 months old), heating panels, reinforced cement panels, plaster boards, provided they are firmly fixed. Particularly suitable for works where rapid repairs are required spacing. N.B.: mixing with Latex Plus
(6 kg of Latex Plus for each 20 kg bag of Keraquick) provides increased deformability (S2), without changing the other positive features of Keraquick. Coverage
2.5-4 kg/m2. Packaging
20 kg bags grey, 20 kg bags white, 4x5 kg packs
this is on the page that give the link to the pdf file.

i also found in the data sheet to prime gypsum although its not really stated as it i would expect.

That 7mm will refer to compressed adhesive bed....not the trowel notch size!

so SBR is ok to use with mapei,im just a bit dubious when mixing products on something as critcal as mapei SP on plaster with BAL SBR i know it wont be a problem its just handy to get it confirm here for peace of mind.
ive already got 5 litres of bal SBR,a punter bought it instead of apd so i bought it of him cheap very cheap.

i know,but its still not much on dodgy walls.:yikes:

 

[grumpygrouter]

Is it not possible to straighten the walls out first then?

 

[oldgit]
