A material used for precise assembly of the element and filling the defect, characterized by a comfortable wear time.

Features

• for the reconstruction of a concrete element
• comfortable wear time (20 min)
• high strength after hardening
• for vertical and horizontal surfaces
• for filling defects in and cracks up to 50 mm
• bright color
• for indoor and outdoor use

Application

The mortar has a comfortable wear time (20 minutes), which makes it suitable for a wide range of users. Ceresit CX 20 Comfort is used for:

• mounting elements made of metal, plastic, etc., e.g. hook w, connector w, anchors, element in electrical installations (electrical boxes and boxes), hinge w, guiding or corner strips, element in installation (technological pipe transitions embedding the element in installation pipes and the handle w) on substrates such as concrete, walls (concrete blocks, cellular concrete, brick, etc.)
• filling defects and cracks with a size of 5 to 50 mm in plasters and walls (e.g. filling installation grooves), floors and all kinds of prefabricated elements, in ceiling and wall elements; larger cavities should be filled with CX 20 Comfort mixed with pure sand in a 1: 1 ratio
• reconstruction of damaged concrete elements, plaster in etc., e.g. wall corners, stair edges

The product is water and frost resistant, therefore it can be used indoors and outdoors, on vertical and horizontal surfaces. The product is also recommended for minor surface repairs, elements in concrete, plaster in.
