Key Benefits of ARDEX PU 30
ARDEX PU 30 is a ready-to-use, single-component primer that is both water- and solvent-free, making it an eco-friendly choice for projects requiring minimal environmental impact. It boasts EMICODE EC1 PLUS certification, ensuring it has very low emissions for improved indoor air quality. The primer’s quick-drying nature allows for reworking within just one hour, enabling faster project turnaround.
The product’s unique formulation penetrates deeply into substrates to block capillary moisture, preventing the effects of residual moisture from compromising floor finishes. This makes it an excellent choice for use on both absorbent and non-absorbent surfaces, including concrete, cement screeds, calcium sulphate screeds, and even old mastic asphalt floors.
Wide Range of Applications
ARDEX PU 30 serves multiple functions, including acting as a barrier against excessive residual moisture in cement screeds and concrete floors (up to 6 CM-% and 98 rH%). It can also be used as a consolidator for sore edge zones on absorbent substrates like calcium sulphate or cement screeds. Additionally, it provides an effective primer for moisture-sensitive surfaces, such as chipboard, OSB, gypsum fibre boards, and even old ceramic tiles or terrazzo floors.
This versatile primer is especially valuable when working with underfloor heating systems, as it provides moisture protection up to 3 CM-% and 85 rH% in cement screeds. It’s also ideal for priming before applying parquet flooring with ARDEX reaction adhesives.
In summary, ARDEX PU 30 is a reliable and efficient primer that ensures a stable foundation for a wide range of flooring applications, offering superior moisture control and substrate consolidation.
