Het whipped lightweight filler, 250 ml

Het whipped lightweight filler, a special extra lightweight filling material for sealing joints, cracks, and leveling substrates (mineral and gypsum plasters, concrete panels, masonry, drywall) in both interior and exterior applications, local repairs of holes, filling and leveling of straight and angled joints in strip or board connections, repairs of cracks in apartment buildings and in drywall structures, excellent for repairing damaged corners.

Key properties of Het whipped lightweight filler:

• Does not drip, does not crack, easy to smooth,
• minimal volumetric shrinkage,
• requires no sanding,
• does not sag after drying,
• for interior and exterior use.

Shade:
non-standard white

Consumption:
depends on the nature and extent of the substrate defect

Drying time:
min. 4 - 24 hours at 20 °C and 60% relative humidity

Diluent:
not diluted. A dry appearance of the filler is not a drawback; it becomes moist when mixed, and the filler can be lightly dampened with water if necessary (max. 1 teaspoon of water per 250 ml of product).

Application:
with a trowel or spatula

Substrate:
dry, mature (pH ≤8.5; testing can be performed with a pH tester), cohesive, unsalted, solid, degreased, free from dust, dirt, and non-cohesive layers, free from biological infestation (mold, algae). Layers of old coatings with insufficient adhesion must be removed, for example, by scraping. For plasters, loose grains of sand must be removed (by sanding and/or sweeping). To improve the adhesion of the filler to the substrate, it is advisable to apply a coat of penetrating agent A-GRUND, AT-GRUND, or 100-GRUND. Metal elements extending into the treated surface must be protected with an anti-corrosive coating (e.g., anti-corrosive paint AQUADECOL PRIMER) before filling.

Application temperature:
the temperature of the material, environment, and substrate must be between +5 and +30 °C (better +8 to +25 °C) during application and for 24 hours (preferably 48 hours) after application.

Example of application procedure:

1. absorbent substrate is penetrated with A-GRUND, 100-GRUND, or AT-GRUND according to the instructions. The penetration is allowed to dry thoroughly.
2. the filler is mixed (a dry appearance on the surface is not a drawback; mixing will moisten the filler, and the filler can be lightly dampened with water if necessary – max. 1 teaspoon of water per 250 ml of product).
3. the filler is applied in one or more layers within an interval of about 4 - 24 hours (depending on the amount of material applied, temperature, humidity, absorbency of the substrate, and other factors). Usually, one layer is sufficient. Immediately after application, the filler can be shaped and its surface smoothed.
4. working tools and contaminated areas must be washed immediately with water.
5. the filler is left to dry until completely dry (min. 24 hours, possibly longer, drying time strongly depends on layer thickness, substrate absorbency, temperature, and humidity). Before painting with paints, it is recommended to re-penetrate the filled areas, preferably with UP-GRUND or with agents A-GRUND, AT-GRUND, or 100-GRUND.
6. After drying, dispersion paints, such as products from the KLASIK, HETLINE, or BRILLANT lines, can be applied. Lime and silicate coatings or paints without sufficient disperse binder content cannot be used on filled areas.
