How to anchor a metallic masonry element

Onsite we must frequently anchor metallic elements such as claws, piping, toilets, pre-frames and hinges, urban furniture, signage, etc., which must be quickly put into operation.

Traditional materials such as fast-setting cement, gypsum or plaster are not the most adequate products, as they oxidize the metallic element in question, in addition to suffering too much retraction, cracking and consequently weakening the required anchorage.

Preliminary analysis

When fixing a metallic anchorage, we must use a mortar compatible with the substrate and the metallic anchorage, due to which it must be:

  • Highly weather resistant
  • Highly adherent to metallic elements
  • Resistant to cracking
  • Fast setting and have compensated retraction
  • Watertight to avoid oxidation of metallic elements.

Technical considerations

Previously, the work to be carried out must be taken into consideration:

  • Fixation of brackets, hinges, stays, signage and urban furniture:

Completely fill the area with GECOL Pronto, and progressively introduce the element to be fixed.

  • Installation of pre-frames and steel frames:

Install the pre-frame or steel frame and seal the brackets with GECOL Pronto or GECOL Cemento rápido.

Next, render the surface using the trowel.

GECOL Pronto and GECOL Cemento rápido, due to be an ultra-fast setting mortar, it is advisable to prepare only quantities that can be used within 1-2 minutes.

The amount of water affects proportionally in the speed of setting, the greater amount of mixing water increases the setting time, when rehydrated by that excess water, the product.
