I hear sometimes tilers grout walls straight after finishing the tiles is this wrong are you better to come back the next day

You hear lots of things over the years.
Your best bet is to actually read the bag of adhesive and follow the instructions carefully, best way to protect yourself and your client.

Interesting......,

I also currently trying to learn how to braid paracord and make shock cord splices and having as much look as sanding tiles

Does this mean you can you could explain the chemical reaction between Portland cement and aluminium?

That sounds a question for a Concrete technologist. I have some knowledge but remember in struggling with a small disc and a slab of clay at the moment

From the manual.
Concrete shall not come in contact with any
aluminum during conveying and placing
operations.

Not sure what you want to know but I thought this may be helpful.

If you want another giggle

Sorry Plan Tec I had completely missed this post of yours - personally I think his tamping stick is patentable and needs branding. The chap with the 'adhesive hands' is a brave one 🙂

Apologies Julian,
Couldn’t find your response, lost track of the thread.
What I’d like to know is about the relationship between Portland cement (used in adhesive) and aluminium when they come in to direct contact with each other.
I know that when grouting heavy machinery legs into a concrete base, Aluminium powder is added to the grout to encourage the grout to expand and lock the machinery in place. However, I also know that as a byproduct, Hydrogen gas is created.
This and it’s possible effects on tile adhesive are the subjects I’m interested in.
Oh, one more thing, is it possible to prime against a reaction taking place? 🙂

Thank you for the link, I only hope I find time to read it, I was kinda hoping I could cheat and get the short version from you as you’ve worked in this area.
My turn to pick your brains, a little reciprocation if you will. 😀
