WEDI BOARD 6X600X1250

wedi building board 6 mm — waterproof XPS substrate 600×1250

wedi board combines a blue XPS core with double-sided cementitious skins reinforced with glass mesh. Flat, fully waterproof and lightweight substrate ready to tile or render; thermally insulating and dimensionally stable.

Key benefits

• Blue XPS — 100% waterproof; remains functional after non-penetrating damage.
• Cement skin + mesh — excellent adhesion for tile adhesives and renders.
• System watertightness with wedi 610 — no extra membrane at joints.
• Thermal/acoustic comfort, mould protection, energy savings.
• Lightweight and rigid; easy to cut and fix on various substrates.

Detailed description

The board provides a flat, strong and watertight surface. Low λ (0.036 W/m·K) and dimensional stability create a warm, reliable base and protect the structure from moisture. With wedi 610, joints are watertight without extra membranes. Cut with knife/saw; fix using compatible adhesives/mechanical fasteners onto sound, level substrates.

FAQ

1) Is extra waterproofing required?

With wedi 610, system joints are watertight; a separate membrane is usually unnecessary.

2) Which adhesives?

C2/S1 tile adhesives plus compatible wedi system adhesives/sealants.

3) Suitable substrates?

Concrete, masonry, drywall, timber/steel frames — if sound and level.

4) Using 6 mm on floors?

As decoupling/levelling layer in system build-ups; choose thicker boards for load-bearing floors.

5) Can I skim/paint?

Yes, over the cement skin with appropriate primers and materials.

6) Storage & UV?

Protect from prolonged UV during storage; in use the board is behind finishes.

7) Corners & transitions?

wedi tapes/profiles; continuous sealing with wedi 610.

8) Cutting & dust?

Knife/saw; minimal dust — use PPE.

9) Service temperature?

−50…+75 °C; avoid continuous overheating.

10) Underfloor heating compatibility?

Yes, within approved system build-ups per UFH and wedi guidance.

11) Dispatch schedule?

Business days only; no dispatch on weekends or public holidays.

12) What is wedi 610 310 ml for?

Adhesive-sealant for bonding/sealing board joints/corners, penetrations, profiles/tapes, shower bases and accessories; forms an elastic, watertight seam; also bonds to mineral substrates.
