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

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.

The Cementone SBR is used in a number of ways, usually as a Bonding Slurry, admixture where it is added to gauging water or as a suction control where it is diluted with water at 1 part SBR to 4 parts water. If used to create a bonding slurry the product needs to be mixed with CEM 1 cement at the volume ratio of 1 SBR to 2 CEM 1 cement and this will give an approximate coverage of 4 m² per Ltr. As a suction control it will be around 25 m² per Ltr ( diluted as above ). As an admixture it will vary depending on what you are doing but typically for a render when adding 5 Ltr SBR to 5 Ltr gauging water and using 25 Kg CEM 1 cement to 62.5 Kg sharp sand, the resulting mortar coverage will be around 4 m² at 12 mm thick.

Do i need to clean the paint and pva from the driveway and start again using SBR or can i put the SBR over the painted driveway as a sealant and re-paint.

Regrettably PVA is not always recommended as a suitable primer for paint. We would urge you to contact the paint manufacturer for advice on preparation before using their product.
If PVA is recommended then it is usually advised to dilute the PVA with 5 parts water to 1 part PVA.
