Can you use SBR on plywood?

If tiling on fibre-reinforced cement sheets, or plywood/chipboard, then we would always recommend priming the reverse side and edges with BAL Bond SBR. This helps protect the plywood from moisture penetration which could cause the board to swell.

Can SBR be used as a primer?

Primer/Sealer BAL BOND SBR can be used on the following areas as a primer or sealer before tiling: – Plaster Dilute 1 part BAL BOND SBR with: For ready mixed dispersions, 4 parts clean cold water.

Do you need to prime no more ply?

Does NoMorePly need priming? The 6mm NoMorePly boards come to PrePrimed. This additional feature of the NoMorePly boards provides a dust-free, water-resistant, and clear surface on which to tile. The boards are only primed on the printed side so the boards should always be installed so the primed side is being tiled.

Why is SBR better than PVA?

One key difference is that, whereas PVA remains water soluble after drying, once dry SBR is not. Consequently, the SBR bonding agent is more suitable for situations where damp might be a factor, such as external finishes, shower areas and swimming pools, as well as in sand or cement screeds and renders.

Can SBR be used on wood?

Pro SBR can be used as a superior priming agent for both porous surfaces including masonry, plaster, cementitious screeds, timber and vinyl and is used extensively by plasterers, floor layers, tillers and in general building works.

How much SBR do I mix?

Mix 1 part SBR to 4 parts water. Brush on to surface and allow to dry. CLEANING 20. Clean tools and equipment with water immediately after use.

How long does SBR take to cure?

BAL Bond SBR Primer & Admix is white in colour, and is available in 1 litre and 5 litre containers. 15-30 minutes drying time.

Will SBR waterproof plywood?

SBR Professional Tilers Primer 1 Litre. Used to seal the surface of No More Ply Boards, this is a premium latex based waterproof primer providing a waterproof coating.

Do you mix SBR with water?


What is the ratio of SBR to water?

Mix 1 part SBR to 4 parts water. Brush on to surface and allow to dry.

Do you add water to SBR?

Mix 2 parts cement to 1 part SBR by volume to a stiff brushable consistency. Do not add water.

How do you mix SBR primer?

The approximate mix is 1 part SBR: 1 part water: 5 parts cement (by volume) giving an approximate coverage of 30m² per 5 litres of SBR per coat. Following preparation of the substrate as detailed above the bonding slurry should be brushed vigorously into the surface giving an approximate 1mm thickness.

Do you have to dilute SBR?

Can I use SBR for tanking?

Construction Chemicals SBR is a white styrene butadiene emulsion used to improve the properties of cement renders, screeds and mortars. It is also used in conjunction with Construction Chemicals Tanking Slurry as a priming coat or tight render basecoat.

What is SBR used for?

It is used across a broad range of applications, spanning everything from car tyres, shoe soles and heels, drive couplings, automotive parts and mechanical rubber goods. A large proportion of SBR is also used in latex form as an adhesive.

What is SBR made of?

It is not ‘pure’ SBR, but a co-polymer which has been doctored and doped and diluted to give it the properties we need in the construction industry (elsewhere it is a major component of tyres and carpet backing amongst other things!) It’s usually sold in 5 litre containers, but regular users will purchase it in 25 litre or even 205 litre drums.

What is SBR paving?

What it is: SBR is more formally known as Styrene Butadiene Rubber. It has an interesting chemistry, with different forms used for different purposes, but in the paving trade, it’s most common use is to ‘beef up’ mortars and concretes.

How well does SBR mortar stick?

This may have already been mentioned, but SBR mortar really, REALLY sticks. As a know-it-all 21 year old, I used it to point setts on a town centre job and, with the wisdom available only to the young and precocious, decided I didn’t need to bother with gloves. A month later, I still had the last few bits clinging to my fingernails.

How much SBR is in a shovelful of cement?

This will typically suggest a rate of so many millilitres per kilogram of cement, rather than the more usual building trade measure of ‘a splash per shovelful’. For a typical (and readily available) good quality SBR product, the suggested dosage rate is 200ml per kg of cement (5 litres per 25kg bag).
