FAST GRUNT K

Bonding primer for difficult surfaces

Usage

FAST GRUNT K is a ready-to-use preparation based on polymer dispersions and quartz fillers intended for priming construction surfaces to strengthen them and increase adhesion. It is recommended for difficult and smooth surfaces such as smoothly troweled concrete, OSB boards, old glaze, terrazzo and laminate flooring requiring the creation of a rough bonding layer on their surface to improve adhesion to the newly applied layers. It can be applied inside and outside buildings at temperatures between +5°C and +25°C.
Types of surfaces intended for application of FAST GRUNT K:
cement and anhydrite floors, cement and cement-lime plasters, gypsum plasters and coats, cellular concrete, silicate bricks, ceramic bricks and hollow bricks, gypsum blocks, ceramic and stone cladding, terrazzo, monolithic concrete, reinforced concrete, magnesia sleepers, gypsum-fiber boards and plasterboard, paint coatings inside buildings.

Properties

FAST GRUNT K is a bonding agent that enables effective application of adhesives, screeds, waterproofing and other materials on difficult surfaces with poor adhesion.
Due to the content of quartz fillers and carefully selected resins, it creates a rough, tacky layer on the surface, which significantly improves the adhesion of the materials applied on it. It is quick-drying and efficient. It can be used on both horizontal and vertical surfaces

Surface preparation

FAST GRUNT K can be used on dry, dust, wax, grease, oil and grease-free surfaces. Any loose, flaking layers must be carefully removed. In the case of weak or crumbling surfaces, it is required to prime the surface with a deeply penetrating agent FAST GRUNT G before applying FAST GRUNT K.

Preparation and usage method

The preparation is ready-made and cannot be thinned or mixed with other materials. Immediately before use, the product should be thoroughly mixed in order to even out the consistency. The emulsion can be applied with a brush or roller to the surface at a temperature of +5°C to +25°C.
The primed surface is ready for further use after min. 24 hours from the end of priming.

USE

Depending on the type of substrate, FAST GRUNT K consumption is about 0.3 kg / m².
