How to mix fibre reinforced mortar | SBR mortar

In this video we mix 3 parts sand, one part cement and some reinforcing fibre in order to make some reinforced mortar to repoint a lead roof valley. This mortar is mixed with SBR instead f water, which helps to make the mortar more flexible and waterproof. Links to the fibre and SBR can be found here-

We used to accomplish a similar effect to the SBR by adding 1-2 cups of bulk PVA glue to a mixer of concrete. Stopped moisture leaching the salt out of our retaining walls.

+Stephen Holmes-Brown Thanks for the info ;-)

[@ultimatehandyman]

@ Philip LindleySBR is a Latex based cement additive that makes the mortar more flexible and waterproof.I would post a link to the product but can't paste any links into the comments section for some reason. If you Google SBR bond you will find it ;-)

[@Thunder_Light207]

Love it hairy concrete, have to do this next year so need to track down that fibre reinforcer, only negative is the fast set time, so I guess mix small amounts throughout the day. Excellent detail and tips Master Handyman many thanks!

[@ultimatehandyman]

I bought mine from eBay- fave.co/2OyIs0c When mixed with SBR mortar it is good stuff ;-) Thanks for the comment

[@RealTimeZone]

This seems like a good idea where cement needs to be waterproof and have resistance to cracking from frost and movement etc. Builders merchants should stock the reinforcing fibre.

+Nick White Thanks for the comment ;-)

[@ladysaw999]

Hello great video. Could this be used for a house foundation, or screed floors? Also does the sbr in the mix help it adhere to old concrete?

No problem 👍

wonderful channel keep up the good work..I am thinking of doing this mix 3sand 1cement for bathroom walls and found equivalent to SBR here in Australia I am going for Bondall Silasec Water Proofer ..but cannot find the shreded fibre fabric ..but can buy the fibre glass fabric in 1 meter by 1 meter size.. if I then shred it using a scissors ..do you think I can get the same result or can I prepare the mix without the fibre

[@ultimatehandyman]

+Danny Dora Thanks, I just found some on ebay in Australia- fave.co/1Sd5C3y I don't think cutting up a sheet of fibre glass will be any good as the strands in the reinforcing fibre are very fine.

[@justgivemethetruth]

Flexible and cement are not two things I usually think of together. There is a lot to learn about this material. Your videos are so varied and informative, thanks. I could not see and you did not mention, I think, if you are working with this kind of stuff do you need breathing protecting and if so what kind do you recommend?

[@ultimatehandyman]

+justgivemethetruth I'm not sure to be honest. There was no heath and safety information on the bag that the fibre came in. I am sure the fibres are made from either polypropylene or polyester and so should not pose a health risk. Wearing a dust mask should ensure that non of the fibres are inhaled, but it's unlikely that they will be airborne if you handle the carefully. Thanks for the comment ;-)

[@justgivemethetruth]

+Ultimate Handyman I've always heard that you should not inhale cement particles for sure, but I have no idea how high they can float in the air. I thought the fibers would be made from silica/fiberglass and did not know about polypropylene fiber reinforcement. I guess you learn something every day on You-Tube. Thanks.

[@ultimatehandyman]

+justgivemethetruth Oh yes, cement is bad and if you are working in a confined space then definitely wear a dust mask when mixing. Plaster is also bad and should not be inhaled. If mixing inside I would definitely wear a dust mask. Thanks for the comments ;-)

[@jasonking2246]

Where can you get the SBR stuff in Australia? I guess it comes under a different brand name ? I just want to mix a small amount of pointing cement for a tile roof ridge, don't want to buy a bucket of the flexible roof pointing compound. Your formula seems to be ideal. Thank you.

[@ultimatehandyman]

It looks like Bunnings stock it- www.bunnings.com.au/lanko-5l-751-lankolatex-sbr-latex-additive_p0967244

[@adrianlawrence5380]

Dear U/H Man I am trying to make a concrete bathroom sink top in a ( top fill mold) in place I f that makes sence and would be grateful if you could advise me on a good mix of cement ( maybe / not sand) and or SBR that will leave me with a good smooth finish without too much in the way of diamond sanding when finishing off. Many thanks Adrian. Great videos very informative thanks

[@ultimatehandyman]

I'm not sure about that, sorry. It's not something I have ever done before. There are some guys on KZbin that make such things, I would ask them 👍

[@paulwary]

We mix the mix until it is mixed. Cant argue with that. 🙂

[@ultimatehandyman]

😂

[@Smuttleydog]

Another great vid!, I've searched the channel but can;t find any clips on burning/welding lead , is it something you have covered yet?

[@ultimatehandyman]

+Richard Grave It's not something I have ever done to be honest. Peter Scholey has some tutorials on how to do it - kzbin.info/www/bejne/bXXFkqCKjc10bcU

If you do tackle it, it will make a great show, All the best Rich

[@ultimatehandyman]

+Richard Grave Thanks Rich ;-)

Does Sbr be always used neat or does it be thinned down its kinda costly if you need a lot of mortar

[@ultimatehandyman]

+jerry o connor I have always used it neat. But if it says on your SBR that you can dilute it then you could do- but it's something I have never done!

[@piee683]

+Ultimate Handyman I was looking on Amazon to purchase two of them mixing buckets you used ,I think they're called tubtrugs only thing is I don't know what size to get can you please tell me if you know what size those black ones you use are cheers

[@rodgerq]

No need for plasticiser then, I take it the sbr does both jobs?

[@ultimatehandyman]

No, as far as I am aware you do not need plasticiser when you use SBR. The SBR makes the mix really sticky! Thanks for the comment

[@jonn8ball]

love the smell of sbr

[@ultimatehandyman]

+John Price I don't mind it but prefer Tarmac LOL

[@user-bo1fq4id2v]

do you know how to improve pva fiber dispersion?

[@ultimatehandyman]

No, sorry

[@nerymary8998]

What's SBR? Is it expensive ? Does it make a project more costly?

[@ultimatehandyman]

SBR makes the mortar stronger and more sticky, it costs about £22 for 5L fave.co/2LbZz5X Thanks for the comment 👍

[@namsoemmanson8338]

Can we mixed PVA with plaster of Paris?

[@ultimatehandyman]

Not sure about that. I always use SBR when mixing mortar, but I’ve never tried it with plaster of Paris 🤔 PVA is not a good thing to mix with anything that could potentially get wet, as it can turn back to a liquid.

[@foryourlugsonly]

that mix looks dryer than a nuns chuff!

[@bigchiponmyshoulder7573]

Not that dry my friend :?)

[@DC-sf5rk]

Did you use sharp sand, or building sand?

[@ultimatehandyman]

Building sand Thanks for the comment 👍

[@DC-sf5rk]

Thanks. Would you use this mix to bed ridge tiles on too?

[@ultimatehandyman]

@@DC-sf5rk You could do, but you only really need the fibre adding to the mix when you are pointing them up, after bedding them down ;-)

[@mrreason9697]

why 3 parts sand here and 4 in previous video?

They are known as concrete fibres/screed fibres- fave.co/3HmCTJm

Hi, could you use this mix to make fibre reinforced cement boards if you left it to cure in a mould?

It's difficult trying to search US websites from the UK as they keep redirecting me to the UK website, but I think Sika make the product for the US and call it SikaLatex fave.co/2oLAdRz
