6 Rules for perfect floor
CERESIT AS 1
Features and Benefits
Apart from its outstanding surface smoothness, the gypsum-based floor levelling compound also features ideal filling properties without hardly any shrinkage or cracking.
- No waiting time after priming calcium sulfate substrates
- Self-levelling and pumpable
- Produces smooth, low-pored surfaces
- Virtually stress-free
- Suitable for use on many old substrates
- Excellent compressive and flexural strength
Advantage for floor installers: They can adjust the consistency according to their needs: slightly creamy with 4.5 liters of gauging water or more liquid with 5 liters. This "trick" has another positive effect. Since the required amount of mixing water is lower than with previous levelling compounds, the surface dries more quickly and is thus faster ready to receive flooring. Despite the comparatively low amount of mixing water, AS 1 has been formulated with even further improved flow and self-levelling properties. Floor layers will appreciate its ease of application: the compound spreads easily to produce layers of 1 to 20 mm thickness without any effort.
AS 1 does not sag
The special formulation of AS 1 ensures optimized filling power and excellent resistance to sagging. Even when levelling large uneven areas, there is hardly any sagging after the compound has dried. This means high security and hardly any risks for the floor layer.
No waiting time after priming
Another advantage: The gypsum-based levelling compound can be applied on a variety of freshly primed substrates without waiting time, for example on new, firmly secured particle and OSB boards, screed and concrete, ceramic tiles, natural stone and terrazzo as well as on old substrates with firmly adhering, water-resistant adhesive residues.
