Recalimed Brick Floor 45sqm Project

[Adam18Spring]

Hi guys following on from my previous wet room build here:
Full Wetroom Build Thread - Start to finish - https://www.tilersforums.com/threads/full-wetroom-build-thread-start-to-finish.88057/

My next project is doing 45sqm of recalimed 150 year old bricks.

So let's start!

The basic build up is an Anhydrite screed with wet UFH.

The system was commissioned back in 2017 and has been in use since. I have turned it off for the tiling process.

I will be working a room at a time to make it easier for me...

So, first off a day spent grinding!

Before

Here you can see the material being removed with the grinder

50/50

Here you can see the texture of the screed coming through

Next up i found the most visible area and then put down a line and started putting lines down at 90 degress so i could bay it out.

Once i had my lines i primered the floor with Tilemasters primer

Then the following day, upon the suggestions here i added tilemaster anti crack matt, stuck down with ayhnfix, i found making the mix slightly runny easier as it soaked into the matt much better.

After that i added my bay lines back ontop to keep me square

Then away with the tiles

Today i did the awkward bit around the stairs

I do have a few questions for you all if you can please?

My sealing/grouting process is going to be:
First Lithofin MN Stainstop
Then grout using a grouting gun 4/1 mix.
Re-seal with Lithofin MN Stainstop

Will this give me a satin finish? I want a nice subtle stain shine.

Personally I don't think you will find stain stop will have any impact when it comes to sealing those at they will be so porous i would treat them as terracotta tiles and treat them with boiled linseed oil followed by Bourne liquid traffic wax

or use a modern method

I've used these a found the very good.

I've a concern about grouting with just sand/cement on a heated screed

What would you be thinking? I was considering NHL3.5 lime initially because it is more flexible....

Never noticed that got to caught up in the sealing

I'd want to use a wide joint flexible grout personally. The limited experience I have with sand/cement grouting is a long time ago during my apprenticeship.

Just put some sbr in the mix...it will help

I want the grout to look a bit 'Sandy' would the wide grout have that look?

 

[J Sid]

Ardex FL is a bit as is bal wide joint.

Yep, a specific wide joint grout has course sand in it

do you mean not grey?

I’m no expert but have grouted a few now with lime - I was advised by mikewye to use nhl5 4-1 mix with yellow sand - used it a few times on heated screeds with success, easy to apply and wash off - looks far better than a modern grout imo.

 

[Adam18Spring]

Not exactly mate, i am after the same sort of color as the Victorian lime pointing, a sort of textured yellow/white color

Great! What was your process? Did you seal first? Did you use a gun to point or hawk and trowel?
Thanks

Well that is not grey......

look for a flexi wide joint sandstone.

 

[Wolfie9878]

sealed first - just surface not joints, then apply with a pointing trowel, let it firm then brush over or sponge if your stone isn’t too rough.

Gun could work just depends how big the aggregate in your sand is as to wether it’ll flow without blocking the nozzle.

I bought a pointing gun to do a similar floor, although terracotta. Threw it away after 5 minutes and switched to pointing trowels and patience. I'd mixed silver sand and cement with sbr. I also tried bal wide joint grout but both just clogged the gun.
I think you can get guns with a paddle built in so you can keep mixing the grout while pumping. Perhaps that's why mine was no good?

 

[Boggs]

Used a pointing gun with lime mortar for my chimney and could not get on with it, found it much easier with trowels.

 

[Dumbo]

As with previous 2 relies tried a pointing gun on reclaimed terracotta. Just kept clogging up

Very rough terracotta done with Bal wide flex and a float

 

[Adam18Spring]

Thanks for the suggestions guys
@Lithofin BOB

Would i be best using Lithofin TC Impregnator and then Lithofin TC Sealer, would this achive the satin finish i am after?

Thanks again everyone, mortar gun is in the bin then....
