RESIGUM

RESIGUM is supplied in pre-measured packages. By correctly mixing the two components, a fluid cement mortar is obtained. This can also be applied vertically to provide waterproof and elastic coatings, which are 1-2mm thick, for concrete structures.
RESIGUM is an ideal protective coating for concrete structures, including industrial buildings, bridges, tunnels, and road works.
Its waterproofing capacity protects against water, aqueous solutions of polluting gases such as nitrogen, carbon oxides, and sulphuric anhydrides.
This protection helps to prevent damage caused by freeze/thaw cycles and penetration of antifreeze salts and gases in aggressive atmospheres, ultimately improving the durability of the structures.
• A RESIGUM coating is highly resistant to aging and preserves in time its elasticity, flexibility and waterproofing features;
• It features good resistance to abrasion which makes it right for pedestrian areas;
• Thanks to its elasticity it can restrain micro-cracks in concrete;
• Good adhesion both on concrete and bricks;
• It can be painted with RESICOLOR 451, 473, 475: these products reduce elasticity of the coating;
• It does not have tar, bitumen and volatile substances.

Preparation of the substrate
Carry out sand-blasting or water cleaning to achieve a clean and healthy bottom, removing any trace of detaching agents, fats and oils, rust and grout.
Even out any imperfections of the foundation (gravel nests, porosities, spacer holes, caissons) and remove possible projecting parts through grinding.
Wet the support until it becomes water saturated; puddles and aquaplaning need to be removed before laying the product.

Preparation of the product
Pour component B (liquid) into a clean, large bucket.Slowly add component A (powder) to component B (liquid) and mix at low speed for 3 to 5 minutes using a drill fitted with a propeller/spiral until a smooth and uniform mixture is achieved.

Application
Avoid application with high temperatures, with wind or with dry surface: these conditions result in fast evaporation of the mixture water and consequently hydration reaction of the cement cannot be completed.
Hardening is only apparent and the coating tends to pulverize.
If you wish to work in such conditions we recommend protecting the coating with wet jute sheets or to spray nebulized water for 1 – 2 days following application.

Notes
Avoid application with high temperatures, with wind or with dry surface: these conditions result in fast evaporation of the
mixture water and consequently hydration reaction of the cement cannot be completed. Hardening is only apparent and
the coating tends to pulverize.
If you wish to work in such conditions we recommend protecting the coating with wet jute sheets or to spray nebulized
water for 1 – 2 days following application.

With constant curing at about +20 °C, RESIGUM coating may be walked upon after 18 hours and
may be subject to mechanical stress after 4 days. Full hardening occurs after at least 7 days.

Consumption

In both cases we recommend applying two layers of product.

Packaging and storage

Available in 26,6 kg packages (A + B component).
