Tiles on concrete - Laying tiles on existing concrete step

[dig dug dan]

A customer has asked me to tile his existing concrete step, including the sides. He has brought the tiles, havent seen them yet.
What is the best method of getting them to stick , especially to the sides, and what should I use to grout them?

[andpartington]

just use a cement mix (3 to 1 ) and grout in the normal way using the same cement after the bedding has gone off

brush a cement slurry on to the back of the tiles and on the step just to be on the safeside I had some lift off once but never since I used the slurry

this is mouthing new quarry tiles have been layed on cement for decades

I would add pva to the cement mix to be on the safe side

Don't use PVA, this isn't designed for outside or damp conditions...

Primer
1:1 Ronafix cement

Bedding Mortar
1 part cement
3 parts medium sharp sand
1:1 Ronafix : water

Clean and prepare the surface; eg power wash, scabble, needle gun, wire brush

Leave damp with clean water

Brush apply Primer

Lay 6mm (min) Bedding Mortar

Clean back of tile, damp and prime with Primer

Lay into Mortar

Allow 24-48 hours to gain strength and bond

Grout

Use

with ref to the use of pva added to mortar etc. Look at Tony's page on repairing concrete.I have used it several times for outside work and it has proved very usefull.
One example was with a slotted concrete post at the end of a run of fencing which the client wanted flush!
I did the job years ago and it is still there.

I can't deny you may have had a success; however there is a distinct performance difference between PVA and our Ronafix, and all the data points to longer term durability, water resistance, bond, strength, with Ronafix than PVA.

This ronanfix is all well and good if you can buy it locally. You can't, so it is out of the question. Trying to get hold of romex for pointing a patio. Cant get it

Couldn't you just buy an end post?

agreed dan ,gear has to be available,
everywhere i go they still got sikafix or geofix,
no sign of any romex
pva has worked fine for me in the past. but i never see ronafix in the merchants so cant use it

If I have to adhere a slab/tile to a step where the slab overhangs the riser, I sometimes use exterior grade tile adhesive.

It is not cheap and goes off in about 20 mins. The tile/slab is not going anywhere with that stuff.

Sand/cement does not adhere it so well butt iis normally perfectly adequate. I would only use adhesive if the tile/slab is in a vulnerable position due to the cost.

Travis perkins dont sell romex. I think this is a different company to ronacrete. I need to buy some for some paving I am doing next week. I am going to order some monday for delivery straight to site so i will let you knowhow I get on

[lutonlagerlout]

i should have said i have never seen romex or ronafix in BMs

cheers LLL (700)

[dig dug dan]

No its not just you. I call the travis rip off.
The staff are rude, unhelpful, and I hate them so much, I would rather travel out of my way to get materials from another supplier than use them.
My mate had an account there and he went in to buy a 9" diamond blade. they quoted him £10. When the bill came, he was charged £70. He queried it and stated he was told £10, and they called him a liar. He closed his account, but before he did so, he gave them a big order, then cancelled it at the last minute!!!
