How To Make A Concrete Bonding Slurry

[@Smitty11946]

Thank you for sharing your knowledge and talent! Researching how to attach a broken statue to new cement for hours because I was told not to do that…never did I expect to hit lotto and click on your page…less alone ever think I would actually have the materials needed! Well bond for mosaics and adding strength to cement…and the fresh Qt. SikaLatex bonding adhesive I add to my pouring medium for acrylic paint pouring!!! Now to hope that the statue lasts for decades!!! Thank you!! I knew it could be done! 😂

Appreciate the knowledge. I just finished my prep on a fairly large public swimming pool and was looking for a proper slurry coat application to fact check my knowledge. Can’t have kiddos in the pool and patches flaking off now can we 😅. Keep posting and remember folks, a clean trowel, is a happy trowel.

My wife and I are about to extend our patio and the idea of just putting new concrete down and nothing to bond the existing concrete with didn’t sit well with us. So thank you for this video!

If you are extending a pad you would want to dowel into the existing pad with steel pins to help anchor one pad to the other.

Very well explained. 👍 .... Especially so, the difference between the two types of bonding agents.

[@tdlin1721]

Thank you so much for your excellent and very informative videos! After viewing most of your videos related to the bonding of old and new concretes, I think I found what I should do to keep my small, about 5"x7"x0.4", flagstones bonded to the top edges of my concrete pool to prevent them from falling down sections by sections into the pool. First, I should choose Latex slurry according to you instructions. Since the stones needs to be bonded to vertical walls, should I add metal screens, such as gutter screens, by pressing it between the old and new slurries? To prevent the stone from separating from the slurries by falling down from its own weight when the slurries are still wet, I am also considering to bend the bottom of 90 degree outward to support the stone when it is sticked to the slurry convering the old concretes. From your practical experienece, please advise if adding metal screens is necessary.

[@ThatNiceDutchGuy]

If you start with the water bottle and take that bottle to measure your glue, it would make more sense. Anyhow, this was just the information I was looking for! Thanks for sharing.

What about using a concrete penetrant before applying the slurry? That would work also, right?

[@irishguy200007]

Do you plaster over it immediately or can you leave it dry.

[@richardpalusaar3364]

You plaster over it before it cures or you are screwed. Or at least so I heard in another video, haha. Search for Cement Slurry on KZbin.

[@Swimmingpoolsteve]

You lay the new topping immediately. FYI since you mentioned plaster, PVA or modified PVA is usually used for plaster renders as opposed to latex as shown is the video above. Both could work depending on your application, but plaster is commonly associated with PVA. kzbin.info/www/bejne/e52xhZuOq9l9Z5o&lc=z23bsjswkxexwbbfxacdp433ho1pdyuoq03xptfo3tpw03c010c

your video was great and thank you for it. i had a tile repair done a few years ago(by Coronado's for $2,000) and it all fell off. I noticed that the concrete behind the tile needed repair. Thanks to your video and some hard work(some concrete repair,cracks, etc.) I THINK I am ready to tile. My question is, can I tile over the slurry? The whole space did not need concrete repair, so some is just slurry surface now. Your answer would be greatly appreciated. Again thank you!

[@jpritch2]

how would you use this to attache pavers to the top of open cinder blocks? Slurry on top of the blocks then mortar? Slurry on the pavers too? I only ask because the last time I did this on a lake sea wall... the pavers did not adhere well at all to the cinder blocks with just plain mortar.

[@miafeete7785]

Can you use quickrete 5000? I don't have just Portland

[@snackymcgoo1539]

Never used portland or concrete. When you finished hand mixing, there are still some clumps. Are those small stones or just maybe in need of a bit more mixing and breaking them down? Or perhaps, they are small enough clumps that while smearing it onto a surface the smearing tool can be used to further smoosh those lumps into uniform paste?

[@Swimmingpoolsteve]

That was due to old cement. New will not do that. It will be smooth

[@johnswimcat]

Thanks Steve, I've been searching for information on how to bond to old concrete and at last I've found it

[@treepro100]

You can also put down A 1/2 inch wet mortar bed before Pouring on existing concrete

[@johnswimcat]

@@treepro100 Thanks for the suggestion Brian. What we did was to clean and saturate the surface of the old concrete with a pressure washer. This produces the condition known as "saturated surface dry" or SSD. While still damp we brushed on an SBR and cement grout and while that was still tacky applied the render mix to the walls of our pool. It's vital not to let the grout dry but as long as it doesn't the bond is really good. Not cheap and a bit fussy but SBR sticks like nobody's business. For the final skim coat of render I used an SBR and cement grout again then a thin coat of mortar made from fine paving sand, SBR, cement and water. This coat was only a few millimetres thick but because of the SBR it has stuck and hasn't cracked. I think a skim coat using white cement, white sand, SBR and a cobalt pigment might be an alternative to pool paint. Needs testing though as UV affects SBR over time. Perhaps grout with SBR but don't use it in the final coat

[@arloarlo5812]

Is bonding slurry used in addition to products like liquid bonding adhesives that you can roll on old damp concrete? (such as Quickcrete makes) Or is applying bonding slurry of this kind sufficient on its own before pouring new concrete on top of old?

Great video, I have patched my pool that had surface holes and very small pinholes as well. The pool was built in 1988 and just now needed some attention. I am wanting to use white portland cement and this bonding agent seems to be a great idea. Paint it on two coats and dry for 48 hours. Is this something that can be done? I see a company that sells a roll-on plaster - but to do my pool their product will cost me a little over $2,000 for two coats. Any suggestions are welcomed - thank you.

[@djrednitro4116]

you need a plaster on top of the concrete. If RollOn plaster is expensive, you can make you own plaster by mixing 1:2 Portland concrete with marble dust

Great Video. Am looking to add 60-70mm to an existing slab, 5m x 3m to build up an existing 75mm slab for a backyard shed. Due to site access complications, I'd probably have to use readymix concrete bags in a cement mixer, and add water, which would make the slab pour more gradual, so I'd be worried about the bonding slurry drying in some areas before they receive the actual pour on top. Could I add a bonding agent direct to the premix and water in the cement mixer maybe?

[@robertgillespie7738]

irishguy200007 No.

[@Swimmingpoolsteve]

Yes you can. If the concrete patch is located in a permanently dry area then this would work fine. However in wet areas the glue will re-emulsify. You can find products similar to PVA (white glue) but are modified to not re-emulsify when exposed to water. Preferably for water applications use the latex method shown in this video above.

[@chriscarr9595]

We have a concrete patio that was poured (1965'ish) right up against the foundation footer of our home to the walkout basement. Up until this year, it was not covered and exposed to the elements for all those years. Right where the footer meets the patio at the doorway, there are quite a few large holes where pieces of the footer have broken off and are deep crevices where even a couple weeds are growing through. Once I get the area cleaned up (figuring chipping away some of the old concrete, then TSP and water), should I use acrylic latex or PVA for this application? It may get some moisture, but is fully covered now. I tried to repair it a couple of years ago and just used a vinyl concrete repair product, and that caused an even bigger looking mess. Thanks for your vidoes!! These have helped a lot and hopefully, this type of application will work for me.

Nice video, what do you suggest to level the floor (concrete slab), as there is a sink in part ( around 1-2 inches) towards the edge of the slab! If I use self leveling it will be very costly as the area is quite large ( 4 by 6 feet into 2 inches!!).

[@Swimmingpoolsteve]

You could form up the area and place and finish the concrete just like you would any other floor. The only problem is the new mix should not zero out, which means it can not blend down to zero thickness. It really should be laid at 1/2" minimum thickness so this must involve cutting or chipping out some of the existing slab.

I hope this isn't too late. In another video he said the slurry should be wet. So clean the area of debris/dust, then wash with 50/50 muriatic acid and water. Dampen the area to be repaired with water, apply the slurry and right away apply your patch cement product.

[@vqfive]

Say you want to bond a old concreted statue to concrete. Could you just use 100% slurry mix only without also adding new concrete if you mixed it thicker

[@Swimmingpoolsteve]

The slurry helps the concrete to grab onto the surfaces, but slurry is not strong like mortar or concrete is so I would say that you need to slurry both sides but you do want some mortar in between to hold the sandwich together. 1" probably the minimum I would use for any appreciable strength.

[@Articulate99]

Infact... never use PVA as a primer/bonding slurry/admixture with cement in any outdoor application... or indoor even. I just dont see the point when you can use an SBR. Thats why all the retail purchased slurrys/additives/2 part mixes from Mapei or Laticrete etc.. are all Latex based.. PVA is wood glue, end of story. Ive seen some companys try and sell a slurry compound and it has been cheaper and i rang and asked... PVA based... just dont bother.

[@Swimmingpoolsteve]

SBR latex will outperform latex acrylic or PVA under some conditions, but it is also the least UV stable and can not be exposed to direct sunlight. It needs paint or mechanical cover or it will fail like an elastic band left out in the sun. PVA is also less of a problem when using modified concrete mixes where acrylic latex and SBR latex can both conflict with admixtures such as accellerants and other polymers. There is no one use fits all application with concrete or concrete bonding, and that is why there is not just one bottle of SBR latex on the shelf.
