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

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.

Answer: 
The Cementone SBR is designed as an admixture for suitable cement based mixes as well as a bonding agent when mixed with OPC cement for suitable applications. It is also sometimes specified as a primer for certain floor levelling compounds and tile adhesives. However the product is not designed or specified as a sealer to be applied over bitumen prior to the application of a cement based product such as tanking slurry, so we cannot recommend its use for such an application.

Answer: 
The Cementone SBR is a product designed primarily as an admixture for suitable cement mixes where it will waterproof and strengthen them and can also be used to create a bonding slurry when mixed with OPC cement for rendering and screeds. However the product cannot be used and is not designed as a primer, sealer or stabiliser over distemper prior a plastering application.

Answers

Answer: 
The Cementone SBR can be used in two ways, as an additive for a cementitious mixes for rendering or screeding where it will waterproof and strengthen these materials when cured, or it can be used to create a Bonding Slurry for applications such as bonding a render to a porous substrate such as brickwork or for bonding a screed to a screed. To create the slurry you mix one part SBR to 2 parts ordinary Portland cement ( CEM 1 ) by volume and brush apply to a pre wetted surface. Apply the mortar whilst the slurry is wet / tacky. ( for rendering 2 coats are required, allow the first coat to dry having stippled first, then apply a second coat of slurry and then apply mortar whist wet, There is no current specification for the product's use with plaster.
