Hello all.

My old tiles are popping out and I am replacing them with broken marbles.

Contractor 1 said just hack off the tiles and about 1 inch of the cement, then can start render and install marble liao.

Contractor 2 said must hack off the tiles and everything until the concrete level (almost 6 inches), then only can start to render and install marble.


Contractor 1 said don't need to hack so much - waste time and waste sand/cement to render back the 6 inches.

Contractor 2 said the other guy is lazy, don't want to hack and re-build. In the future, the marble will easily crack.


Anyone got any idea?

One will do.
Coz he hack into existing cement layer already minus 1 inch. If existing cement layer is not those tao kung kam liu like school cement all sands no cement then OK. Else if all sands cut corner 1..need to hack till concrete. Technically existing cement shud be very stronk as it cured many years d right?

another question..

Contractor 1 - cost how much

Contractor 2 - cost how much

which one profits more? I mean $$$ to be given...

I have no idea whether they got cut corner last round or not...

I don't know what you mean "cured many years" but the house very old and I'm not the first owner... Probably 25 or even 30 years old.

Contractor 1 bao ka liao RM8k including work and material

Contractor 2 RM5k for labor only, sand cement and material I buy

Area is around 650 sq ft

Go with contractor 2

Cured many years means already ripe and hard
Concrete need 4 weeks to fully ripen so to speak
The older the concrete the stronger it is.. drilling in 10 years concrete wall is not the same as drilling in 60 year old concrete

But that depends on the underlay.. the safest is to hack all.. if it is still strong i.e. not loose sand with sprinklings of cement (cement is exp, sand is dirt cheap) then no need hack all.

sand and cement is cheap. you need about 2 tonnes broken marble. 1 tonnes cost around RM300-RM400.
