A Properly Selected Primer Is the Foundation of a Durable Floor
A durable floor system always starts with properly prepared substrate. Only on a well-prepared base can functional and aesthetic layers be built. This is the stage you don’t see – but it ultimately determines the longevity and appearance of the finished flooring system.
Before installing screed, microcement, resin flooring, broadcast systems, or leveling layers, the concrete substrate must be prepared to meet key parameters such as load-bearing capacity, stability, and adhesion.
We are often asked to provide independent assessments of “defective floors.” In many cases, we can clearly identify mistakes made at the priming stage. Don’t let this happen in your project.
We strongly believe that concrete priming requires responsibility, expertise, and proper product selection.
There is no room for compromises or shortcuts here – these will inevitably lead to problems in the future.
Why Use an Epoxy Primer for Concrete?
A properly selected and applied epoxy primer (also known as a concrete primer) is a key component of any flooring system. It:
- Strengthens and stabilizes the substrate (especially weak or dusty concrete)
- Improves adhesion of subsequent layers
- Equalizes substrate absorbency (critical for decorative systems and thin layers)
- Reduces dusting and seals porosity
- Minimizes moisture impact and reduces the risk of defects (e.g., blistering, delamination)
In simple terms, a primer creates a bonding layer, stabilizes the surface, and prepares it for further application.
It also reduces common execution issues such as:
- delamination
- bubbles and blisters
- uneven curing
- surface dusting
A primer combines bonding, impregnation, and stabilization in one – making it a standard solution in industrial, garage, and decorative flooring systems.

How to Choose the Right Epoxy Primer? 4 Key Factors
Selecting the right primer should always be based on substrate parameters – not product “universality.”
The key factors are:
1. Concrete condition and quality
(strong vs. weak, dusty, porous, absorbent)
2. Moisture level
(e.g., <4%, <6%, up to ~8%, depending on the system)
3. Mechanical loads
(pedestrian traffic, forklifts, heavy machinery)
4. Type of finishing layer
(screed, microcement, broadcast system, decorative or industrial flooring)

BAUPOX 100 GP – Deep Penetrating Epoxy Primer for Weak Concrete
A two-component, solvent-based epoxy primer designed for weak and dusty concrete.
- Deeply penetrates and strengthens the substrate
- Stabilizes structure and reduces dusting
- Suitable for base layers, polymer screeds, anchoring, and repairs
Best used when:
Concrete is old, weak, highly absorbent, or uneven, and deep penetration is required.
Consumption: 0.3–0.5 kg/m²
BAUPOX 100 ST – Universal Epoxy Primer for Concrete and Screeds (Also Slightly Damp)
A two-component, solvent-free, transparent primer.
- Suitable for concrete and cement screeds
- Can be applied on slightly damp substrates (up to ~8% moisture)
- Provides excellent adhesion and uniform bonding
Additional benefit:
When mixed with aggregate, it can be used as a repair mortar for cracks and minor defects.
Best used when:
The substrate is stable but slightly damp or requires minor repairs.
Consumption: 0.25–0.5 kg/m²
BAUPOX 100 STX – Reinforced Epoxy Primer for Heavy Loads
A two-component, solvent-free primer with filler, designed for dry concrete (<6% moisture).
- Creates a very hard, abrasion-resistant layer
- Increases substrate strength
- Ideal for industrial environments
Best used when:
The floor will be exposed to heavy traffic, machinery, and high abrasion.
Consumption: 0.25–0.5 kg/m²
BAUPOX 100 K – 2-in-1 Epoxy Primer and Decorative Coating
A two-component, solvent-free, pigmented epoxy resin.
- Functions as both primer and topcoat
- Reduces application time and material usage
- Ideal for decorative systems (e.g., with colored flakes)
Typical applications:
- garages
- technical rooms
- warehouses
- offices and commercial spaces
Best used when:
You want a durable and aesthetic finish while optimizing time and cost.
Requirement: substrate moisture <4%
Consumption: 0.25–0.5 kg/m²
Why Choose BAUTECH Epoxy Primers Instead of Random Products?
Using a “random” primer is one of the most common causes of flooring failures. Poor selection often leads to incompatibility with the substrate or subsequent layers.
BAUTECH BAUPOX offers a system-based approach:
- Primers designed as part of a complete flooring system
- Precise matching to substrate parameters
- Improved adhesion and durability
- Reduced risk of defects (blisters, delamination, uneven curing)
- In the case of BAUPOX 100 K: time and cost savings thanks to a 2-in-1 formula
Quick Guide: Which BAUPOX Primer to Choose?
- Weak, porous, dusty concrete → BAUPOX 100 GP (deep penetration)
- Concrete/screed with moisture up to ~8% → BAUPOX 100 ST (universal)
- Dry concrete (<6%) + heavy loads → BAUPOX 100 STX (reinforced)
- Dry concrete (<4%) + decorative finish → BAUPOX 100 K (primer + topcoat)
Summary: Choosing the Right Epoxy Primer Is an Investment in Floor Durability
Selecting the right epoxy primer for concrete determines whether your floor will remain durable for years—or start failing prematurely.
Whether you are working on a warehouse, industrial hall, garage, or showroom, the primer is the foundation of the entire flooring system.
The BAUTECH BAUPOX range allows precise matching of the primer to real substrate conditions—its quality, moisture, and expected loads.
The result:
- better adhesion
- fewer defects
- long-term performance and reliability
