ECOFONDO® A+B+C
Waterborne epoxy 3 component coating
Waterborne 3 component product based on liquid epoxy resin with hydrolytic binders, to be used as primer for substrates even with humidity from ground-up.
Type: Funds, Consolidants, Primers
Description
Three-component formulation based on water-based liquid epoxy resins and hydraulic binders, used as a base for surfaces, even wet and counterthrust, for the realization of breathable resinous cycles.
Use
Connecting layer and regularization of cement surfaces.
Base layer for resinous floor coverings in the presence of damp substrates.
Grouting of pitting and surface cracks.
Primer for tile supports.
Support
The substrate must have a minimum compressive strength of 25 N/mm2 and a tensile strength of 1.5 N/mm2 .
Preparation of the support
The support must be properly cleaned manually and / or mechanically in order to eliminate non-cohesive parts, encrustations, efflorescence, dust and grease.
Flooring must be treated mechanically, by sanding, shot peening or milling.
Surfaces tending to flour should be treated in advance with a recovery of PAVIWATER T68 diluted 1:3 with water, proceeding with fresh ECOFONDO on fresh.
Application
Prepare the mixture of the 2 liquid components (A+B) by pouring the contents of part B into the container of part A; mix with a drill for about 2 minutes.
Add the pre-dosed hydraulic binder to the mixture (A+B) and mix with a mixer drill for about 1 minute. To disperse the product optimally, it is necessary to pour the powders little by little, continuing to stir with the drill.
Dilute by weight by 15% with fresh, clean water and apply with an airless roller, brush or spray, for a consumption of 0.30 kg/m2 . For airless application we recommend the use of abrasion resistant nozzles 0.025" ÷ 0.029" with a pressure of 150÷180 bar.
ECOFONDO can also be applied by trowel. In this case, load the A+B+C system with 50% of QUARZO B1 and apply using a smooth American trowel, for an ECOFONDO consumption of about 0.50 kg/m2 .
In the presence of high humidity ECOFONDO can be applied in several stages (consult the Sivit Technical Service).
Warning: avoid preparing partial mixtures of the product in order not to incur accidental errors, which could lead to incomplete hardening.
Product for professional use, the buyer undertakes to follow the above warnings in the application of the purchased product and the instructions in the safety data sheet.
