Ronafix SBR
ronacreteshop....
Ronafix is a single-part SBR admixture for cement mortars that enhances physical and chemical properties, allows mortars to be placed in thin sections, provides waterproofing and resistance to frost, and promotes adhesion to building surfaces.
Mortars containing Ronafix are used for many applications where thin high-strength high-performance mortars are required.
The typical minimum application depth is 6mm.
Ronafix is supplied as a single-component white liquid. According to its specified use within mortars, it is diluted with water and added to cement, sand (and aggregate) to provide the required performance characteristics. As a priming or bonding coat, Ronafix is used with cement only to provide adhesion between substrate and mortar.
Applications For Ronafix Include:
• Floor screeds
• Concrete repair
• Waterproof renders
• Slurry coats/levelling and protective
• Heavy-duty floor toppings
• Protection of steel reinforcement
• Bedding and bonding mortars
• Tanking and waterproofing

I had to do the external door reveals to my garage, I just happened to get the reminder for this new video and just happened to watch it before I did the render.. I had some SBR from the past in my shed, read the instructions (1 part SBR to 2 parts cement) and made up a cement paste which closely resembled floor levelling compound. My door reveal had them stupid plastic cavity closers with no strength however using this stuff on them and some expanded metal lathe I can safely say my render went on fine and stuck. Did it in 2 coats, but having never done external render before after watching this video I became more confident and gave it my best shot. A good video, came just in time, thanks 👍👍👍

[@Plastersmurf74]

Mate , I’ve had another look at your channel, you’re such a diverse guy. You cover so many subjects, your presenting and editing skills are really good, and, you have a go at plastering. I find plastering is one of those areas that general builders do not touch, but you my friend, have taken that on, and are at a competent level with it, great channel , lots to learn here. Great job fella! Many thanks Andy

[@TheFatNumpty]

I don't think I've ever seen anyone pull the quality faces like Roger does in that thumbnail, always makes me chuckle 😂

[@tonydalton6756]

I haven't used SBR for too long but it amazes me how well it sticks with cement as a slurry. Once it's gone off there is no separating it from whatever you stick it to.

[@Mick_T63]

I’ve used Ronafix years ago for concrete repairs, Also it’s good for screeding floors where you need a thinner layer on uneven surfaces. Great stuff.

[@garethjones6082]

Im doing my Level 3 Domestic Retrofit and Sustainability Advisor at the moment and your video's visualise the theory we are learning. Thankyou

[@SkillBuilder]

Excellent!

[@SJWardBuilders]

Never leave home without SBR!!

[@jacquesmertens3369]

My girlfriend says I have bonding issues. Thanks for your advice.

[@I-am-not-a-number]

She tells me that too.

[@SkillBuilder]

Tell her you just need to try it out on a few different test pieces. Scientific research.

[@robertbamford8266]

Learn something new. SBR = Styrene Butadiene Rubber. Several products in US. Will check out for stucco repair! Thanks for info.

[@truefoa]

SBR all the way for outside and some inside jobs for me. Not seen Kurt's video yet, will have a look.

[@johnhaydon4055]

Another vote for SBR here Rodger, I always use it if customers want a suspended timber floor tiled, never had any callbacks.................yet!! ATB from J and H Builders

[@SkillBuilder]

Thanks John, good to know.

[@roostercogburn9097]

Do you use it as an admix for the adhesive or prime the floor with it first? What ratio? Cheers

[@norris5353]

I've moved from PVA to SBR. Good old Kirk. SBR seems to have a multitude of uses 👍🏻

[@dave1secondago]

brilliant info as always on SB

[@shaunglendinning]

Great advice Roger!

[@kf5541]

There’s a balance between strength and flexibility on substrates and varying hard standings. I always liked 3:1 then 4:1 with Sika 1. The plastering guy you showed lays on skim to dry sbr. I would not recommend that method as once dry it creates a barrier. Nice to see you laid on to wet sbr Nigel.

[@lazylad8544]

Bond was a great agent

[@AdityaMehendale]

:) Ah, a fellow viewer with ADH.. Oh, look, a squirrel!

[@jamiejones642]

Render grip is my go too

[@paul756uk2]

Im not in the building trade but amazed at howsome builders have never heard of it.

[@SkillBuilder]

You are right, it is strange to find that.

[@joejoey316]

That's a great idea with the glass! I heard the pink sbr is the besr!

[@joejoey316]

Best

[@dave1secondago]

got this on my shopping list now

[@melinda5777]

Thank You!

[@SashaXXY]

Hello. Thank you for the upload! I actually had no idea that there was this agent that you could use as an intermediate layer between masonry and some other material. Is this how they stucco light wooden frame residential homes? Like once the plywood is on the frame, do they put this stuff on plywood to make the masonry stick? But how does the moisture membrane fit between that?

[@asencyel]

What about horizontal applications on floors where PVA is used not as a primer but adn admix?

[@matthewgartell6380]

I love the smell of SBR

[@TheSockWomble]

Go and work in a carpet shop you will love it 😂

[@Quebicrecords]

Plasprime green grit isn’t a bad shout for a good grab when rendering it contains SBR too

[@chris-w4n9w]

Kirk sells his own super strong pink SBR now

[@SkillBuilder]

He is a man with a plan, I can see him having a television show before long.

[@dantheman1337]

​@@SkillBuilder You are forgetting that TV isnt watched like it used to be. Probably a TV show gets fewer views than a KZbin show

[@chrisbrown9558]

Ha ha - thought I recognised that voice on radio 2😊

[@vixh1555]

Can you use SBR when rendering a fireplace?

[@SkillBuilder]

yes I have done it

[@vixh1555]

@@SkillBuilder great thanks 👍

[@TheNomadBuilder]

Got any jobs going on the channel 😅 - how do I get involved?

[@gdfggggg]

I don’t use anything else. Bonding, waterproofing etc. I had a customer with an underground outhouse where when it rained hard water would come through the bricks. I did x2 coats of 50/50 SBR cement, no sign of water or damp ever again. I once had a splatter of it on my old van and I just couldn’t get it off 😂. It’s the do all additive. PVA just doesn’t compare.

[@metatron007]

Nice Information

[@robyndavis3043]

Very interesting

[@ParallaxRS]

Why nobody has made a bonding agent called Agent Bond I’ll never know!

[@JoannaLouise200]

I thought the best Bonding agent was Roger Moore...oh, I think I have my wires crossed :)

[@stuartsear4474]

Hi can you advise me what would be the best to do, i am changing a 1300 x 700 rad but can't find one that size so would it be best to fit a 1300 x 600 or a 1200 x 700 thanks Stuart.

[@GaryHerberson]

For the same heat output, have you considered a double or even triple rad? You can look online and every manufacturer will give you a BTU output for a rad, which you can use to compare the rads. Hope this helps

[@I-am-not-a-number]

Andy the roofer swears by FBR.

[@djmusk6015]

Pva and cement mix makes for some serious bondage.

[@johnjones4825]

Perhaps I'm a bit dim or uninformed. In South Africa, any form of covering something with a cement mixture is generally called plastering. What is the difference between rendering and plastering?

[@GaryHerberson]

I'm not a builder, but I think rendering would be a more durable material like concrete, more waterproof to the environment amd so its excellent on external walls. Plastering definitely is not so strong or robust but so could get a smoother, better finish. So plastering would be used for internal walls where damp is not going to be an issue. Base material would be something like gypsum.

[@Wizowes95]

In the UK plastering is done indoors while rendering is outdoors.

[@jamessmith8217]

Pva is not for external use with sand and cement it says it on the tub in bold lettering. Sbr is a far superior product for external use and has many different uses. Another stupid video from Roger.

[@ricos1497]

Back in my day, we'd just lick the walls and then render. That was when men had proper saliva of course, filled with grit and faeces, not like today's molly coddled woke generation.

[@irbfenian2594]

faker

[@tackleberryc6472]

I hock a loogy.on the wall and alls good...

[@kempshott]

I've just discovered the hard way that if you add SBR to repointing mortar for crazy paving, brick acid doesn't work nearly as well cleaning up the mess.

[@SkillBuilder]

That is true

[@geoffm9944]

Great video advice about bonding agents Roger, but with the U.K. disappearing down the waste hole with huge and relentless economic problems, law and order going down the Swanee with soaring knife crimes, housing crisis which can’t be solved, and massive problems with unlimited immigration, talking about bonding agents seems slightly bizarre.

[@SkillBuilder]

Ha! when I do political rants I get people saying ' stick to DIY' or whatever. We like to mix it up on this channel but the political stuff is all about building so talking about some of those other issues is jumping the shark.

[@u2kjib4cjkqn]

Don’t waste your time HP 14

[@SteveAndAlexBuild]

Yeah sticks like shit . We were putting copings on and we were using SBR / cement slurry on the wall and the copings . I had holes in my gloves so had it all over my finger tips … couldn’t get it off for days !!!! 😩🧱👍🏽
