Use method

Ensure that the substrate is robust and free from loose parts. With any existing deteriorated plaster, strip the surface until restoring the masonry. Create through-holes on the section to be reinforced, using a rotating drill bit or core drill. The diameter of the hole should be equal to that of the connector plus at least 6 mm. The number of pass-through connections is to be determined by the drafter (usually between 3 to 5 connections/m2). Do not use percussion tools for drilling through-holes. Once formed, proceed with a proper blowing and suction of the hole to eliminate any debris. Secure the connector with hydraulic lime-based grouts (such as our SANAFLUENS), cement-based grouts (like our GROUT CABLE) or with chemical anchors (such as our SYNTECH PROFIX). Wet the substrate and apply an initial coat of mortar by hand or with a plastering machine until reaching a thickness of about 1.5 centimetres. Be quite vigorous if working manually or – even better – with a plaster spray machine, leaving the surface of the mortar sufficiently rough, without any smoothing operations, to facilitate the adhesion of the subsequent layer. Place the primed alkaline-resistant fibreglass mesh of the ARMAGLASS line (see the technical data sheet of the chosen product), placing it on the still-fresh mortar by passing the connector between the bars of the mesh and opening the ends of the same in accordance with a radial distribution. Finish with the application of a second coat of mortar at a thickness of about 1.5 centimetres. The temperature of the substrate must be between +5° C and +35° C. Do not apply at temperatures of around 0° C.
