PIASKOWIEC + SPECIALCHEM — Properties and performance
- Preparation and impregnation of sandstone
Preparation and impregnation of sandstone
Substrates
- Relevant substrates include sandstone on compatible facades, walls, fences and stone details. Also assess joints, coatings and adjacent elements. Mark out a trial area, record product consumption and inspect the result before continuing with the remaining work.

Technical documentation
Data from the product description and technical documentation. Follow the current label for the supplied variant and confirm working conditions by a substrate trial.
Surface preparation
First test a small, inconspicuous area.
- Start by selecting cleaner concentration and testing compatibility. After cleaning, remove residues, rinse as instructed and wait for the material to dry completely.
- Carry out a compatibility trial and assess the complete result before treating a larger area.
PIASKOWIEC + SPECIALCHEM — Application method
- Cleaner: lightly pre-wet the substrate, leave for 5–10 minutes without drying and rinse. In a sprayer, dilute at least 1:1 and no further than 1:10, depending on the method. Apply one coat of impregnation to completely dry stone.
- The cleaner irritates skin and eyes: wear gloves and goggles; do not use on aluminium. This kit’s instructions require at least 2 hours without water after impregnation.
- After treatment, check the uniformity of the result and follow the conditions for subsequent use stated on the label.
Conditions and drying time
The cleaner irritates skin and eyes: wear gloves and goggles; do not use on aluminium. This kit’s instructions require at least 2 hours without water after impregnation.
Consumption, packs and calculations
Cleaner: approximately 10–20 m²/l; impregnation in the kit description: approximately 10 m²/l (0.1 l/m²).
Use the components separately. Do not add cleaner and coating volumes together to calculate coverage.
| Pack sizes | Indicative pack coverage |
|---|---|
| 1 L impregnation + 1 L cleaner | Establish by trial and from the label |
| 2 L impregnation + 2 L cleaner | Establish by trial and from the label |
| 5 L impregnation + 5 L cleaner | Establish by trial and from the label |
| 10 L impregnation + 10 L cleaner | Establish by trial and from the label |
| 20 L impregnation + 20 L cleaner | Establish by trial and from the label |
Example for 50 m²
PIASKOWIEC: Establish by trial and from the label; PIASKOWIEC CLEAN: Establish by trial and from the label
Maintenance and limitations
No single numerical service life is stated for all applications. Assess surface condition and retreatment needs according to use.
- Do not apply to dirty surfaces or incompatible coatings. The impregnation does not remove existing stains or replace crack repair or waterproofing. Assess protection on a clean surface and adapt renewal to service conditions.
- The components have separate purposes and requirements. Do not mix them; plan cleaning, rinsing, drying and impregnation as distinct stages.
Storage and safety
- 3 years from the production date. Store in tightly closed original packaging in a dry, ventilated place, protected from overheating. Follow the label’s temperature requirements.
Read the current label and safety data sheet before use. Wear the required personal protective equipment. Do not mix with other products.
PIASKOWIEC + SPECIALCHEM — Product questions

Planning your project with PIASKOWIEC + SPECIALCHEM
Use PIASKOWIEC + SPECIALCHEM as a two-stage sandstone treatment: clean, rinse and allow the surface to dry before applying the impregnation. Calculate each component separately and confirm the quantity on a representative trial area. Follow the current labels for the supplied kit.
Explore the NANO-BAU product catalogue to compare applications, or contact NANOBIZ.PL for help identifying the appropriate product. This page describes PIASKOWIEC + SPECIALCHEM; it does not replace the instructions supplied with your particular pack.
