Craftsman Trade Advice

Essential technical rules from master tilers for durable tile installations.

Substrate Prep

Drainage Slope & Pedestal Subbase

Outdoor patios demand a mandatory 2% drainage slope away from the house foundation. For unbound gravel or pedestal installations, ensure the crushed-rock subbase is firmly compacted.

Sightline

Center Tiles on Living Room Patio Doors

Align the terrace layout with sliding patio doors or living room sightlines. Positioning whole pavers at the threshold creates a continuous indoor-outdoor transition.

Joint Physics

Open Joints & Edge Restraints

Leave open 3–5 mm spacer joints between 2cm outdoor pavers to allow rainwater to drain beneath. Restrain perimeter edges with concrete haunches or metal edge profiles to prevent lateral shifting.

Frequently Asked Questions

How much tile waste should I calculate for an outdoor patio?
Calculate 10% cutting waste for simple rectangular patios on pedestal supports, increasing to 12% if cutting around veranda posts, rainwater downspouts, or curved garden borders.
Which tile size makes an outdoor patio feel larger and more expansive?
Large 60×60 cm or 80×80 cm pavers visually expand outdoor living areas, creating broad, uninterrupted sightlines into the garden. For exterior durability, ensure pavers are solid 2 cm (20 mm) thick porcelain to resist freeze-thaw cycles and ground heave.
Should patio paver joints align with interior living room floor joints?
Aligning exterior terrace joints with interior floor tiles through glass sliding doors creates continuous indoor-outdoor flow, visually expanding both living spaces.
How do I tile around perimeter edges and thresholds on a patio?
Use sturdy aluminum edge profiles or concrete haunches along unrestrained slab edges to prevent lateral shifting, leaving an unbonded expansion gap at exterior door thresholds.
