Rated 4 out of 5 by top product use this all the time to seal walls prior to tiling. Much better than pva. creates a very strong bond. good price too 18 May 2015
Rated 5 out of 5 by Seals the deal! Great product with fantastic properties. I used it to seal the external walls within a bathroom prior to plastering to prevent any moisture penetrating through the brick work. Works a treat 4 Apr 2015
Rated 4 out of 5 by great for priming screed i used this to prime my cement screed floor before applying self levelling screed. i applied it with a kitchen spongey cloth, it dried in about an hour and worked perfectly. the screed didnt lose its moisture into the floor, so remained workable and flowing for ages. it doesnt outline how to use as a primer on the bottle (seems to be mainly an additive) but i just poured it neat. 24 Mar 2015

use for tanking

I read on the data sheet that the product can be applied as a tanking liquid. However, there are no more details. Could you please provide instructions.

Answer: 
Thank you for the enquiry.
I am sorry to say that this is an error and we will be removing the statement from the container and any other instructions.
We would normally recommend the use of a tanking slurry which is designed for the purpose.

I have lined bathroom with 'No More Ply' boards, now before I start tiling shall I use a 1:3 mix of Cementone SBR / water? I understand SBR should be done (applied with roller?) prior to tiling and not to use PVA. Can anyone confirm and thanks in advance.

Answer: 
The Bostik Cementone SBR product is designed primarily for use as an additive for suitable cement based mixes and applications. It can also be used to create a bonding slurry using OPC cement to bond renders and screeds to suitable substrates. The product is also sometimes specified for use as a primer for certain tile adhesives and floor levelling compounds but there is no general specification for these types of applications. Consequently you will first need to source a suitable tile adhesive for your application which includes one that is suitable for the type of tile and substrate you are bonding to, then follow the instructions on the tile adhesive product regarding any priming for that product which may or may not include SBR.

Answer: 
The Cementone SBR Admixture White 5 Ltr is designed primarily to be used as an additive for cement mixes in such applications as renders or screeds where it will waterproof and strengthen these applications when used correctly. Other uses include creating a bonding slurry when mixed with CEM 1 cement and is sometimes specified as a primer for certain floor levelling compounds and tile adhesives. However the product is not designed or specified for use as a sealer by itself and so in this instance, its use in your application is not recommended. N.B. If you intend to apply a final finish to these surfaces, then you will need to follow the manufacturers instructions of the product you intend to use regarding any priming or sealing prior to the use of their adhesive or final finish product.

Answer: 
The Cementone SBR admixture product is designed as an additive for cement based mixes where it can be used to waterproof and strengthen render and screed applications. It can also be used to create a bonding slurry where it is mixed with OPC cement to act as bonding aid for a render to a wall or a screed to a concrete base. The product is not designed or specified to act as a sealer for old wallpaper paste prior to the application of plaster.

Answer: 
The Cementone SBR Admixture product is designed for use as an additive for cement based mixes for renders or screeds where it will water proof and strengthen the resulting material. It can also be used to create a bonding slurry which acts as a bonding aid for renders and screeds when mixed with OPC cement. However in common with both the PVA and Waterproof PVA products we do not have a specification for the products use as primer or sealer for paints, or indeed for encapsulating asbestos. For advice on using a paint for your application including suitability and sealing /priming, you will need to contact the manufacturer of the paint you have.

Answer: 
If you want to do it properly, you need to use a proper encapsulating paint. The industry standard for this is Bostik's Idenden ET150 paint, which comes in 10 litre tubs for about £50. You can paint it on with a roller, brush or sprayer.
You can paint it straight on to the bare cement without any surface prep.
