Waterproof microcement in bathroom and sanitary ware, facts, layers and principles of professional implementation

Why are bathrooms and toilets the most challenging spaces?

Wet spaces have always been the enemy of building coatings 💧

We face the following things in the bathroom and toilet:

Direct contact with water

Permanent steam

Chemical detergents

Temperature changes

Not every material can tolerate these conditions ❌

Is microcement inherently waterproof?

Let's be clear 👇

Microcement alone is not waterproof.

But: ✔️ if it is implemented systemically

✔️ have complete waterproof layers

✔️ Basic infrastructure should be done

👉 The final result will be completely waterproof and reliable.

How does microcement waterproof system work?

Water resistance is the result of a multi-layer system, not a single material.

Waterproof microcement implementation layers (from zero to hundred)

Layer 1: Substructure and primary insulation

First of all:

Floor and wall are checked

Slope is corrected

Water penetration points are identified

If needed, basic insulators are used 🧱.

Layer 2: moisture resistant primer

Primer for wet spaces:

Increases adhesion

Controls surface absorption

Prevents the penetration of moisture into the next layers

Layer 3: implementation of fiberglass mesh

Fiberglass mesh:

Diffuses tensions

Inhibits hair cracks

It plays a key role in waterproof durability 🧵

Layer 4: Microcement layers

Microcement is implemented in several stages:

base layer

Final layer with selected texture

🎯 Uniform implementation is vital at this stage.

Layer 5: The final waterproof sealer

The most important part of the system 💎

Specialized sealers:

Polyurethane or resin

Resistant to water and detergent

Anti-stain and anti-fungal

Without this step, it does not make sense to be waterproof ❌

Advantages of microcement in bathroom and toilet

✨ No seams → no mass accumulation

✨ Luxurious and integrated appearance

✨ Easy cleaning

✨ The possibility of running on old tiles

✨ Suitable for renovation without destruction

Comparison of microcement with tiles in humid spaces

Ceramic tiles

dams where pollution accumulates 😬

Need for demolition in reconstruction

Repetitive appearance

Microcement

Smooth surface

Modern design

Fast execution

Fatal mistakes in the implementation of bathroom microcement ❌

🚫 remove the final sealer

🚫 Use of poor quality sealer

🚫 Running on a wet surface

🚫 Ignoring the slope of the floor

🚫 non-specialist implementation

⚠️ These mistakes cause water penetration and complete failure.

Storage of microcement in humid spaces

To extend life:

Use mild detergents 🧼

Avoid acids and strong scale removers

No matter how many years the sealer is renewed

Why is professional performance vital in wet spaces?

Bathroom is not a place of trial and error 🚿❌

The smallest mistake = water penetration + structural damage

The experience of Decamo Cement team means:

Knowledge of critical points

Choosing the right waterproof system

Controlled and guaranteed execution

Final summary

If executed correctly:

✅ Microcement in the bathroom is completely waterproof

✅ It has high durability and lasting beauty

✅ It is a modern alternative to ceramic tiles

But only if

👉 Substructure, layers and implementation should be completely basic.
