Het whipped lightweight filler, 250 ml

Het whipped lightweight filler is a special, exceptionally lightweight filling material designed for repairing cracks, joints, and leveling substrates (mineral and gypsum plasters, masonry, concrete panels, drywall) in both indoor and outdoor environments. It is suitable for local repairs of holes, filling and leveling straight and angled joints in board or strip connections, for the remediation of cracks in drywall structures and in apartments of panel buildings, and it also serves excellently for repairing damaged corners.

Key properties of Het whipped lightweight filler:

• Does not run, does not crack, easy to smooth,
• minimal volume contraction,
• does not require sanding,
• does not sink after drying,
• for interior and exterior.

Shade:
non-standard white

Consumption:
depends on the nature and extent of defects in the substrate

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

Thinner:
not thinned. The dry appearance of the filler is not a disadvantage, it moistens with mixing; the filler can be lightly dampened with water (max. 1 teaspoon of water for 250 ml of product).

Application:
with a trowel or spatula

Substrate:
must be dry, mature (pH ≤8.5; control can be performed with a pH tester), solid, coherent, free of grease, salts, dust, dirt, and non-cohesive layers, without biological contamination (mold, algae). Old layers of paint 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 priming agent like A-GRUND, AT-GRUND, or 100-GRUND. Metal elements protruding into the treated surface must be treated with an anti-corrosion coating (e.g., anti-corrosion paint AQUADECOL PRIMER) before filling.

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

Example of application procedure:

1. Absorbent substrate is primed with A-GRUND, 100-GRUND, or AT-GRUND according to the instructions. The primer must be allowed to dry completely.
2. The filler is mixed (a dry appearance on the surface is not a disadvantage; mixing moistens the filler, and it can also be lightly dampened with water – max. 1 teaspoon of water for 250 ml of product).
3. The filler is applied in one or more layers at intervals of about 4 - 24 hours (depending on the quantity of material applied, temperature, humidity, absorbency of the substrate, and other factors). Usually, one layer is sufficient. Right after application, the filler can be shaped and smoothed.
4. Working tools and contaminated areas must be immediately washed with water.
5. The filler should be allowed to dry until completely dry (at least 24 hours, possibly longer; drying time is highly dependent on layer thickness, substrate absorbency, temperature, and humidity). Before painting, it is recommended to re-prime the filled areas, preferably with UP-GRUND or with A-GRUND, AT-GRUND, or 100-GRUND products.
6. After drying, dispersion paints can be applied, e.g., products from the KLASIK, HETLINE, or BRILLANT series. Lime and silicate paints or paints without sufficient content of dispersion binder are not allowed on filled areas.
