ECOFONDO® PLUS A+B+C
Waterborne epoxy 3 component coating
Three-component water-based epoxy primer with high vapor barrier behaviour.
Base coat for cover cement surfaces even in the presence of damp substrates. Withstands hydrostatic pressure up to 500 kPa.
Excellent tile adhesion.
Suitable for Radon barrier coatings.
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.
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 PLUS 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 15% by weight with fresh, clean water and apply in double replies with an american trowel, for a consumption of about 0.6-1.0 kg/m2 for each shot.
Before proceeding with the coating required by the finishing cycle, wait 24 hours (at 25 °C and 50% R.H.) verifying complete drying with a hygrometer.
Warning
Avoid preparing partial mixtures of the product in order not to incur accidental errors, which could lead to incomplete hardening.
