Why the distinction matters
We get asked this question constantly: "What's the difference between all these finishes — and which one should I choose?" It's a fair question. Microcement, tadelakt, marmorino and Portola Paint all create beautiful, textured, artisan-style surfaces. From a distance they can look similar. But they are fundamentally different products with very different performance characteristics — and choosing the wrong one for the wrong location can mean costly repairs down the line.
The single most important factor is simple: is the surface going to get wet? That one question determines everything else.
Microcement is our most versatile finish and the one we apply most frequently across Los Angeles. It's an ultra-thin decorative coating — just 2–3mm thick — made from cement, water-based resins and mineral pigments. Applied directly over existing surfaces, it creates a completely seamless finish with no grout lines and no joints.
The key advantage of microcement is waterproofing. When sealed with a professional-grade sealant system, microcement is fully waterproof — making it the right choice for showers, bathroom floors, kitchen splashbacks and any surface that will regularly get wet. It's also the only finish on this list that works on floors, where it needs to withstand foot traffic, furniture and daily wear.
In Los Angeles homes we use microcement in full bathroom transformations — walls, floor and shower surround in one continuous surface — as well as kitchen floors, outdoor terraces and living room floors. The result is a seamless, spa-like finish that looks extraordinary in both modern and transitional interiors.
Best for
- Shower walls and floors
- Bathroom floors and walls
- Kitchen floors
- Kitchen splashbacks
- Countertops
- Living room floors
- Outdoor terraces
- Full room floor-to-wall
Not ideal for
- Purely decorative accent walls where cost matters (marmorino or Portola is more economical)
- Heavily textured artisan look (tadelakt has more organic character)
Tadelakt is a traditional Moroccan lime plaster that has been used for centuries in hammams and riads. It's burnished by hand using a smooth river stone and finished with olive oil soap — a process that creates a naturally waterproof surface with a distinctive warm, organic texture that no modern product can fully replicate.
Like microcement, tadelakt is suitable for wet areas — but it achieves waterproofing through a different mechanism. The lime carbonates and the burnishing process compresses the surface, creating a dense, water-resistant finish without synthetic sealants. This makes it a popular choice for clients who want a more natural, artisan aesthetic in their bathrooms and showers.
Tadelakt has a warmer, more handmade quality than microcement — you can see the slight variations in the burnished surface that make every application unique. In Los Angeles, we apply tadelakt most often in boutique master bathrooms, spa-inspired shower enclosures and feature bathroom walls where a sense of craft and history is part of the design brief.
Best for
- Shower walls
- Bathroom walls
- Bathtub surrounds
- Spa-inspired interiors
- Organic, artisan aesthetics
- Feature bathroom walls
Not ideal for
- Floors (microcement is better for traffic)
- Large open-plan spaces
- Perfectly uniform, modern finishes
- Countertops and kitchen surfaces
Marmorino is a traditional Italian decorative plaster made from crushed marble dust and lime. When polished, it creates a luminous, semi-reflective surface with extraordinary depth — the marble particles catch the light in a way that looks almost three-dimensional. It has been used in Venetian palazzi and grand European interiors for centuries.
Marmorino is strictly for dry areas. It is not waterproof and should never be used in showers, bathrooms (on wet walls), kitchens or any surface that gets wet. This is the most important thing to understand about marmorino. In the wrong location, moisture will cause the plaster to fail.
Where marmorino excels is on feature walls in living rooms, entry ways, dining rooms and bedrooms. The polished marble-dust surface creates a finish that looks genuinely luxurious — with depth and movement that paint simply cannot achieve. In Beverly Hills and Bel Air homes, we apply marmorino as a statement finish in double-height entry halls and formal living rooms where the light catches the surface dramatically throughout the day.
Best for
- Living room feature walls
- Entry halls and foyers
- Dining room walls
- Bedroom accent walls
- Office and commercial walls
- Anywhere a luxurious, luminous finish is the goal
Never use in
- Showers or wet areas
- Bathroom walls
- Kitchen splashbacks
- Floors
- Exterior surfaces
Portola Paints — specifically their Roman Clay and Lime Wash products — have become enormously popular in Los Angeles interior design over the last several years. They offer a beautiful, textured, organic wall finish that photographers love and that reads beautifully in the warm California light. You'll see it constantly in design-forward LA homes, on Instagram and in architectural publications.
Portola is a paint-based finish, not a plaster. It's more accessible than true marmorino or tadelakt — easier to apply, available in a wide range of colors, and generally lower cost. The Roman Clay product creates a soft, earthy texture with natural-looking variation. The Lime Wash creates a more chalky, aged, layered effect.
Like marmorino, Portola is strictly for dry areas. It is not waterproof and cannot be used in wet areas. It's an accent wall and dry room finish only. That said, for a bedroom feature wall, a living room statement wall or a powder room (where direct water contact is minimal), Portola creates a stunning result at a very accessible price point.
Best for
- Bedroom feature walls
- Living room accent walls
- Powder room walls
- Entry hall walls
- Any dry wall needing texture and depth
- Budget-conscious decorative finish
Never use in
- Showers or wet areas
- Bathroom wet walls
- Kitchen splashbacks
- Floors
- High-humidity environments
Side-by-side comparison
| Finish | Wet areas | Floors | Feature walls | Waterproof | Durability |
|---|---|---|---|---|---|
| Microcement | ✓ Yes | ✓ Yes | ✓ Yes | ✓ When sealed | 15–20 years |
| Tadelakt | ✓ Yes | ✗ Not ideal | ✓ Yes | ✓ Natural lime | 10–20 years |
| Marmorino | ✗ No | ✗ No | ✓ Yes | ✗ No | 10–15 years |
| Portola Paint | ✗ No | ✗ No | ✓ Yes | ✗ No | 5–10 years |
The decision guide
→ Microcement is the answer. It's waterproof, seamless, goes over existing tile with no demo, and can cover walls, floor and shower in one continuous surface.
→ Tadelakt on the walls. If the floor gets heavy traffic, use microcement on the floor and tadelakt on the walls.
→ Marmorino for maximum luxury and depth. The marble-dust composition creates a finish that genuinely looks like a high-end material — not paint.
→ Portola Roman Clay or Lime Wash. Especially good for bedrooms, powder rooms and living room accent walls where you want organic texture without full plaster cost.
→ Microcement is the only finish that can do all surfaces — floors, walls, wet areas and dry areas — in one continuous application.
Can you combine them?
Absolutely — and in many of our best projects, we do exactly that. A common combination in Los Angeles luxury homes is microcement in the bathroom (floors, shower walls and wet surfaces) combined with marmorino or Portola on the bedroom feature wall adjacent to it. The two finishes complement each other beautifully and each is doing what it does best.
Another popular pairing is microcement floors throughout the main living areas with tadelakt on a statement bathroom wall — creating a cohesive, tactile language across the home that feels curated rather than matched.
During your free in-home consultation, we'll look at every surface you're considering and give you an honest recommendation — which finish, why, and what the result will look like in your specific space and light conditions.
A note on our work in Los Angeles
LA Microcement applies all four of these finishes across greater Los Angeles — from Malibu beachfront homes to Beverly Hills estates to modern lofts in Silver Lake and Culver City. We are licensed applicators with deep experience in all these materials, and we work closely with interior designers, architects and general contractors as well as directly with homeowners.
Every project starts with a free in-home consultation where we assess the surfaces, discuss your design vision, and recommend the right finish for every location. We never oversell — if Portola Paint is the right answer for your bedroom wall, that's what we'll tell you.
