What is SBR primer?

0.00. NoMorePly® Primer is a Premium latex based waterproof primer. It is used to seal the surface of NoMorePly® boards to improve the bonding strength of the tile adhesive. It helps to reflect heat which enhances the insulation value of NoMorePly to make it better for use with underfloor heating.

Is SBR primer the same as PVA?

SBR, or Styrene Butadiene Rubber, is a water resistant bonding and sealing agent, and shares many similar characteristics with PVA. One key difference is that, whereas PVA remains water soluble after drying, once dry SBR is not.

What does SBR primer mean?

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.

What do you use SBR for?

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.

How do you use SBR as a primer?

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. For cement based powders, 2 parts clean cold water. Dilute 1 part BAL BOND SBR with 4 parts clean cold water.

Can I paint over SBR?

Hi yes you be able to to paint over it all you'll need to do is rub it down a bit to give it a key then give it two coats. Hope this helps.

Can I use SBR as a sealer?

Resistant to wet conditions once set, SBR bonding agents can be used as an adhesive, sealer and to add waterproofing qualities.

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.

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.

Does SBR seal concrete?

SBR Bond Benefits: Greatly improved adhesion to a wide range of substrates including dense concrete, steel, tiles etc. Mixes may be applied in much thinner sections.

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 before tiling?

BAL Bond SBR is also useful as a primer before tile fixing, providing extra protection for peace of mind. USE FOR: enhancing the physical properties/performance of mortars including adhesion, durability, flexibility, waterproofing and workability.

How do you make slurry mix for paving?

Use a mortar mix of 6 parts sharp sand to 1 part cement. Mix together with just enough water to make it damp and workable, but not overly wet and runny. PLEASE NOTE that ALL granite paving MUST have a cement & SBR liquid slurry mix painted on the entire back on the slab before fixing.

How long does bond SBR take to dry?

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

Should I use PVA before rendering?

Paint the surface with a coat of PVA before application of the mortar. It can be applied undiluted for maximum sealing and/or adhesion, or diluted as above. The mortar or render is best applied when the PVA is slightly tacky.

What is SBR bonding?

SBR Bond is a latex based, water resistant bonding agent and admixture for use in areas subject to humidity, dampness and continuous water contact.

What does SBR stand for?

styrene-butadiene rubber (SBR), a general-purpose synthetic rubber, produced from a copolymer of styrene and butadiene.

Do you seal render before painting?

You don't necessarily need to seal your new render before you start to paint over it. You should apply at least a thinned first coat as a mist coat. You should then apply the appropriate number of coats on top of it to finish the project. This is usually enough to start the painting process.

Can you use masonry paint on render?

A water-based masonry paint it is easy to apply with brush, roller, spray or paint pad and will cover all the usual surfaces — render, brickwork, pebbledash and concrete — well.

How do you use SBR on paving slabs?

Add the SBR to the dry cement mix slowly while mixing to avoid lumps, continue until you achieve a gloopy consistency that coats the back of the paver. If the paving is very light in colour and is prone to absorption, we do recommend using a white cement, this will minimise the risk of discoloration.

How do you make a SBR priming slurry?

To produce the bonding slurry dilute SBR Bonding Additive with an equal volume of water then mix to a smooth creamy consistency with ordinary Portland Cement. 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.

What's the best mix for laying patio slabs?

Paving slabs are bedded in a mortar mix with four parts sharp sand to one part cement. Measure your quantities using a shovel or a bucket - for example, four buckets of sand for every one bucket of cement.

Can you use SBR on plasterboard?

SBR is for areas subject to damp, moisture and constant wetness. If you were going to render your walls and just leave them it would be the stuff to mix in the render, if you are going to plasterboard and then tile, then it has little use and PVA will be suitable.

Can I use SBR to Prime plasterboard before tiling?

Yes, prime bare plasterboard.

How long can I leave primer before tiling?

The surface should be rendered and allowed to cure for at least 7 days. Remove flaking paint, roughen surface by mechanical means. Thoroughly remove water-based paints. Existing tiles should be sound, free from dust, grease, oil, etc.
