ECOFONDO ONE® A+B+C
Waterborne epoxy 3 component coating
Semi-self-eveling three-component water-based epoxy primer.
Base coat with excellent vapor barrier for cover cement surfaces even in the presence of damp substrates.
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, to obtain the vapor barrier effect for reverse hydrostatic pressure values of 250 kPa.
It offers rapid hardening even in conditions of low temperatures and high humidity.
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, such as encrustations, efflorescence, dust and grease.
The floors must be treated mechanically, by means of sanding, shot peening or milling.
Surfaces tending to chalk should be treated in advance with a recovery of PAVIWATER T68 diluted 1:3 with water, proceeding with fresh ECOFONDO ONE on fresh.
Application
Prepare the mixture of the 2 liquid components (A+B) by pouring the contents of part B into the container 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 1minute. To disperse the product optimally, it is necessary to pour the powders little by little, continuing tostir with the drill with the drill.
Apply with an American trowel, for a consumption of about 2.0 kg/m2 for each shot.
Before proceeding with the coating, with subsequent resin coatings, wait 24 hours (at 25 ° C and 50% R.H.) checking with hygrometer the complete drying.
Warning
Avoid preparing partial mixtures of the product in order not to incur accidental errors, which could lead to incomplete hardening.
