How to renew old tile shower base?

[susi]

Hi I need to renew my shower base. Its old tiles pressed into a concrete slab. I want to get rid of the tile look and have it look like a single flat floor and change the colour! I tried to paint but it doesnt stick, can I spread tile grout all over,(or whatever that stuff is that you stick tiles on with)

  

let it dry and then paint? Will the grout stick? I dont want to put concrete over the top unless its just a smear so paint will stick... what can I do? Can I glue something waterproof over it, like waterproof vinyl or something? Right now its a mess and don't want to spend a fortune...

Hi Eric,  I am wondering, now that things actually stick to the rustoleum touch up, for example the painters tape wouldn't stick to original tiles but sticks to the newly painted surface - had a job to get an edge started to pull it off. So can something more durable now be put over the top and use the rustoleum like a primer base? I know you keep saying do it professionally, but it would mean a jack hammer to get the old tiles out of the concrete base. The slab that is our floor is the ceiling of the unit below, so it gets a bit tricky as would not want to compromise the slab. I would love a new shower and base but I can't see how it can be done without a lot of effort and expense.

Hi Eric, me again

Just been thinking, I know you said it hasn't been rated for shower base, and time will tell  but Rustoleum Tile Transformation say in their kit that you can even repaint your bath tub. So as it would be soaking in a bath tub in fairly hot water for perhaps longer than a shower takes and subject to scum that needs washing off, I figure based on their claims that it would withstand a shower base even better. Its not difficult to paint over again if it starts wearing a few years down the track, so its a cheaper option if you don't mind a bit of maintenance now and again.

Hello @susi 

I'm sorry but the Rust-Oleum Kit is meant to be used only on the surface. It can't be used as a primer and covered over with tiles.  

In regards to the maintenance of the coating, it's not difficult to paint over. I agree with you that it is a cheaper option than re-tiling your entire bathroom area.

If you need further assistance, please let us know.
