Application steps

SUBSTRATE QUALITY

Substrate quality: Substrate should be smooth and solid

Substrate preparartion: If the substrate is rough, a fine gunite layer on the substrate with a min. thickness of 50 mm is required and cleaned without loosen aggregates, stones, nails wires, etc.
If steel existed, such as girders, reinforcement mesh, anchor, etc., a min. 50 mm gunite layer is a must as a cover.
