Lavasteen Portobello

Lavasteen Seamless Floor & wall – Portobello concrete look

Why choose a finish that lasts for decades? Lavasteen Seamless Floor in Portobello stands for responsible construction and daily comfort. The system is designed for long-term performance in homes and projects.

Natural lava stone minerals and an advanced epoxy system form one seamless surface: completely waterproof, highly scratch-resistant and ready for intensive use. Cleaning remains simple.

Portobello is a warm, earthy taupe shade that exudes calm. The colour allows wood, black steel and light natural stone to harmonise beautifully and suits a wide range of styles.

Less frequent replacement requires fewer raw materials and transport. The ecological footprint decreases visibly. Portobello is a sustainable choice that also pays off financially.

Sustainable benefits at a glance

• 100% waterproof – ideal for shower trays, bathrooms and kitchens; even if the top layer is locally damaged, the base layer remains waterproof.
• Seamless & hygienic – no joints; stains cannot penetrate and cleaning is quick.
• Highly scratch-resistant – Lavasteen reinforces the matrix; suitable for residential, hospitality and office spaces with heavy traffic.
• Underfloor heating compatible – thin layer with efficient heat transfer; suitable for new builds and renovations.
• Control over appearance – pour and trowel: sleek-minimalist or subtly vibrant.
• Low-maintenance – daily cleaning with mild products; aggressive cleaners are not required.

What is Lavasteen Seamless Floor?

Lavasteen seamless floor is a 2-component system based on concrete stucco and epoxy: an A-component (base mass with pigment) and a B-component (epoxy hardener).

After mixing, a firm, spreadable paste is created. You pour the material out and distribute it manually with a trowel on floor and wall; this way you maintain maximum control over texture, nuance and movement.

Unlike a fully self-levelling epoxy resin floor — which flows out by itself — Lavasteen Seamless Floor gives you control. The concrete look therefore aligns precisely with the space and desired style.

Applications & Substrates

Residential: living rooms, kitchens, bathrooms/showers, staircases and bespoke furniture. Commercial: retail spaces, hospitality venues and offices with intensive use.

New build & renovation: seamless, low-maintenance finish with a sleek, matte look.

Adheres to: concrete, cement, tiles (with primer), plaster, wood and MDF. Working over tiles? Level the joints and the entire tile surface with Stucopaste and use primer for optimal adhesion.

In wet rooms, the system remains completely waterproof and hygienic — ideal for showers and bathrooms.

Apply Responsibly Yourself

Sustainability starts with getting it right first time. Our installation guide minimises waste and margin for error. In summary:

1. Prepare the substrate – stable, clean and level; apply primer for adhesion where necessary.
2. Mixing – stir component A until homogeneous; add the weighed component B and mix for 2–3 minutes.
3. Layer 1 – apply thinly and tightly; remove tape; allow to dry for at least 24 hours.
4. Layer 2 – choose tight or subtle movement; lightly mist and distribute the "slip coat" with a flexible trowel for nuance.
5. Curing & sanding – cure again for approx. 24 hours; sand with grit 80 (short = anti-slip, longer = smoother).
6. PU topcoat – protects against yellowing and simplifies maintenance; can be applied in multiple layers if desired.

What's included in the package

• Lavasteen Seamless Floor mix in Portobello (7.15 kg – A and B components, pre-weighed mixing ratio).
• Primer (recommended) – for optimal adhesion.
• PU topcoat (optional) – UV-resistant and protects against yellowing.
• Clear instructions – step-by-step guidance.

Comparison with other finishes

• Lavasteen Seamless Floor (Portobello) – applied manually with trowel; matte concrete look; extremely hard, scratch-resistant and fully waterproof; ideal for floor & wall, suitable for homes, new builds and underfloor heating.
• Epoxy resin floor – fully self-levelling and industrially smooth; less suitable for residential/new-build/underfloor heating.
• PU poured floor – elastic and comfortable; works well with underfloor heating, but less hard/scratch-resistant than Lavasteen Seamless Floor.
• Traditional Beton Ciré / microcement – cement-based; only waterproof with additional PU layer; less wear-resistant.
