UZIN PE 260 is a highly concentrated, film-forming dispersion primer for preparing both absorbent and dense substrates. The primer is mainly used before the floor is levelled.
UZIN PE 260 is used undiluted on smooth, dense or moderately absorbent substrates. On absorbent substrates, the concentrate can be diluted with water, depending on the application, up to a maximum of 1:3.
This makes PE 260 widely suitable for both renovation and new construction, forming a reliable bonding layer between the existing substrate and the smoothing compound.

Suitable substrates
UZIN PE 260 can be applied to, among others:
- Cement-based screeds
- Sand-cement screeds
- Absorbent concrete floors
- Calcium sulphate and anhydrite screeds
- Ceramic tiles
- Natural stone
- Terrazzo
- Water-resistant coatings
- Epoxy resin coatings
- Old mastic asphalt floors
- Magnesite floors
- Properly secured chipboards
- Properly secured OSB boards
- Suitable wooden substrates
- Old renovation floors
- Well-adhering, water-resistant adhesive residues
- Well-adhering smoothing compound residues
- Subfloors with hydronic underfloor heating
- Floors subject to castor wheel traffic
The exact dilution and preparation depend on the type, absorbency and condition of the substrate.
Application on dense substrates
On smooth, dense and non-absorbent substrates, UZIN PE 260 is generally applied undiluted.
Examples include:
- Ceramic tiles
- Natural stone
- Terrazzo
- Water-resistant coatings
- Epoxy coatings
- Old mastic asphalt floors
- Dense renovation substrates
- Well-adhering, water-resistant adhesive residues
After drying, the primer forms a film to which the subsequent smoothing layer can bond.
Application on absorbent substrates
On absorbent substrates, UZIN PE 260 can be diluted with water to a maximum of one part primer to three parts water.
Examples include:
- Cement-based screeds
- Sand-cement screeds
- Absorbent concrete
- Calcium sulphate and anhydrite screeds
- Absorbent smoothing compounds
The correct mixing ratio depends on the absorbency of the substrate. A highly absorbent floor may require a different dilution or an additional treatment.
No moisture barrier
UZIN PE 260 is a bonding and suction-regulating primer. The product is not a moisture barrier against rising damp or an excessively high residual moisture content.
Before application, always check that the substrate is sufficiently dry. In case of moisture problems, a suitable UZIN moisture barrier must be applied.
Substrate preparation
The substrate must be load-bearing, dimensionally stable, permanently dry and clean, and free of cracks and substances that could reduce adhesion.
Remove:
- Dust and loose particles
- Oil, grease and wax
- Non-water-resistant adhesive residues
- Loose smoothing compound residues
- Weak or insufficiently bonded layers
- Paint and coating residues that are not sufficiently bonded
Sand or roughen smooth and dense substrates if necessary. Then vacuum the floor thoroughly.
Always check old adhesive and smoothing compound residues for adhesion and water resistance before applying the primer.
Mixing and application
- Allow the packaging to acclimatize before use.
- Shake or stir UZIN PE 260 thoroughly.
- Use the product undiluted on dense and less absorbent substrates.
- Dilute the product on absorbent substrates according to the UZIN product data sheet, up to a maximum of 1:3 with clean water.
- Apply the primer evenly and thinly with a suitable nylon roller.
- Use a brush for edges and hard-to-reach areas.
- Avoid thick layers and puddle formation.
- Allow the primer to dry completely before applying the smoothing compound.
- Clean tools with water immediately after use.
Coverage and drying time
| Substrate | Dilution | Concentrate consumption | Drying time |
|---|---|---|---|
| Dense or low-absorbency substrate | Undiluted | up to approx. 150 g/m² | approx. 1 hour |
| Normally absorbent substrate | Diluted with water | depending on dilution | approx. 1 hour |
| Highly absorbent substrate | Up to a maximum of 1:3 | from approx. 40 g/m² | approx. 1 hour |
The values apply at approximately 20 °C and 65% relative humidity. Low temperatures, high humidity and thick layers extend the drying time.
Indicative coverage per canister
| Concentrate consumption | Coverage per 10 kg canister |
|---|---|
| 40 g/m² | approx. 250 m² |
| 80 g/m² | approx. 125 m² |
| 100 g/m² | approx. 100 m² |
| 150 g/m² | approx. 67 m² |
The high coverage of 250 m² can only be achieved with a suitable diluted application. The substrate ultimately determines how much product is required.

Why choose UZIN PE 260?
UZIN PE 260 combines several applications in a single primer. Undiluted, it forms a bonding layer on dense and low-absorbency substrates. Diluted, it regulates the absorbency of cement, concrete and anhydrite floors.
Thanks to its concentrated formulation, the product offers high coverage and allows the mixing ratio to be adjusted to the substrate. This makes it a practical multipurpose primer for a wide range of smoothing applications.
