Searching around for faux concrete slab or artisan cement effect wall finished but was put off by high prices, faux concrete slab can cost as much as RM40.00+ psf while artisan cement effect wall cost around RM14.00 psf.

Had a long discussion with contractor and we agreed to remove existing paint to see what's underneath, both were surprised the precast concrete looks good so decided to bring out its natural beauty. After paint removed, we sand it even then painted it with a waterproof sealant to prevent cement dust, drew some lines to bring out the effect too. Renovation still going on and these are the pix I have for now.

Those aiming to achieve this kinda feature wall, perhaps can check if your desire wall are using the precast concrete.

Around RM12.00 psf provided your original base is concrete slab.
