A balcony faces sun and rain. A wrong fall can send water toward the door or the apartment below, so start with drainage.
Water and substrate
Trace water from the farthest point to the drain and inspect the threshold and any stains below. If old tiles have lifted, find the cause first. Adhesive and grout do not repair failed waterproofing.
Choose the finish
Specify outdoor-rated tile with suitable slip resistance and materials compatible with the balcony exposure. Dark or large tiles make temperature movement and joints especially relevant. Plan cuts around the drain.
Handover and quote
Separate demolition, base repair, falls, waterproofing, testing, tiling, junctions and waste removal. Before final grouting, check that water moves toward the drain rather than collecting at the door.
Include in the request
- Dimensions plus photos of threshold and drain.
- Photos of stains below, if any.
- Condition of existing tile and joints.
- Need for demolition or waterproofing inspection.
Frequently asked
Can I tile over an existing balcony floor?
Only after checking bond, heights, falls and waterproofing. Another layer can make drainage or the threshold worse.
Will fresh grout stop a leak?
Not if the waterproofing has failed. The construction and junctions need diagnosis.
Which tiles suit an outdoor balcony?
Choose tiles the manufacturer rates for outdoor use with suitable slip resistance, and agree on a compatible laying system.
