• Multi purpose • Latex based • Waterproofs • Primer/ sealer Sika SikaBond SBR+ Waterproof General Purpose Bonding Agent and Mortar Admixture has numerous uses as an admixture (mortar/screeds/renders), primer / sealer (tiling applications) and a bonding agent (screeds/renders). SikaBond SBR+ can also be used as a flexibliser for cementitious based tile adhesive when tiling on wooden/asphalt floor. In addition, SikaBond SBR+ has the advantage over PVA bonding aids in that it is not adversely affected in wet conditions, has excellent resistance to water and water vapour, and has improved frost resistance, therefore making it ideal for exterior use. SikaBond SBR+ has a reduced water to cement ratio for equivalent workability, making it easier to spread and can be applied in much thinner sections. SikaBond SBR+ also has a high level of resistance to salt permeation, a reduced surface dusting of concrete and a greatly improved resistance to many chemicals.

Wordsworths Driffield Verified Purchase

Used it to repair a deep concrete sill by bonding coat then fine sand/cement/SBR skim coat tapered from 8mm to 1mm. Bonded and finished easily with a steel float, leaving a slightly textured surface . Then overpainted after curing.

Preferable to PVA when plastering.

Preferred to PVA when evening out suction on plaster repairs. Costs more but saves time.

Easy to apply. Doesn't smell as bad as some SBR. Only problem is that if you don't use it all in one go it tends to get a sticky cap - but this is common with this type of dispenser independent of brand

Master of one Verified Purchase

Easy to follow instructions, easy to use and definitely does the job. Not cheap but you get what you pay for. If mixed with sand and cement render as an admix it makes it very workable. When used as a bonding agent it won’t let go.

Good stuff!

First time using SBR. I used it 5 to 1 cement and SBR (and a smidge of water) to make a slurry primer when laying Indian sandstone on sand and cement. It certainly grips very well, with a fairly generous layer it really grabs in a short time and the 5L tub seems to go a long way.

Perfect as a basecoat on old brickwork. Formed a good seal before application of exterior paint. Has withstood many bouts of heavy rain. Well worth the money!

Added to ready mix render, resulted in very strong render finish.

Great addictive for wall cement. It makes sure the cement is waterproof and bond beautifully. The cheaper version (about 7 times less) of this addictive is less useful as it is a very diluted version. You get what you pay for. Stick with this one instead.

Sticks ok to wall

Can’t really review it until I see if it survives winter. Instructions clear.
