Microcement in Barcelona: cost and where it works

Half of microcement’s appeal in an older building is not aesthetic but logistical — and the logistics matter double when the owner is not in the country.

What skipping demolition buys you

• No permit stage: refinishing a surface is decoration, with no municipal filing to wait on
• No rubble down a stairwell with no lift, no container licence, no complaints in the president’s letterbox
• No noisy days squeezed into the hours the local ordinance allows for works
• No surprises behind fifty-year-old tiles: what stays closed cannot ambush the budget
• Two or three millimetres of build-up: doors keep their clearance and floor levels stay untouched

The window between tenants

A bathroom or kitchen renewed in four to six working days, with no demolition phase, fits inside a vacancy period that a full retiling never would. For a landlord managing the flat remotely, that difference — days instead of weeks, decoration instead of works — is usually the deciding argument.

Where the building punishes it

Microcement transmits whatever the substrate does. On a vaulted floor that flexes, or over old tiling with hollow or debonded pieces, the substrate’s movement ends up drawn on the surface within months. Coating a support that moves is postponing the problem and paying for it twice — the pre-application check matters more than the brand on the bucket.

The encaustic-tile warning

Under paint layers or 1980s tiles, many period flats hide original encaustic cement floors — the patterned mosaic that cannot be bought new, only rescued from demolitions. Covering a healthy one with microcement destroys value that a future sale would have paid for. Before coating an old floor, open a small test patch; if sound encaustic tiles appear, restore them and keep the microcement for the bathroom, where they never reached.
