Preparation:
New ground supported concrete should incorporate an integral physical functioning DPM within the construction in accordance with building regulations.
Substrates should be dry, structurally sound and free from contamination, friable materials, laitance and contaminants which may affect either the adhesion or penetration of the Altro Proof system. All residues of old paint coatings and dust must be fully removed mechanically in order to achieve maximum adhesion.
Substrates should achieve 26 N/mm² compressive strength (BS EN 12504-2:) and surface tensile strength 1.5 N/mm² (BS EN 13892-8:).
