RESICOLOR 440
IMPREGNATING AND STRENGTHENING AGENT FOR POROUS BUILDING MATERIALS, BASED ON EPOXY RESINS IN WATERY EMULSION
Impregnating and consolidating agent with epoxy resin base in aqueous emulsion, stops surface dusting in concrete. Recommended as dust protection for concrete industrial floors, brightens up colours, creating a wet look. Can be used to encourage adhesion of other epoxy coatings.
RESICOLOR 440 waterproofs the treated surface without creating a film because it acts by impregnation; colour is brightened up but not altered because the product does not contain any pigments.
Following treatment, the surface becomes waterproof to liquids, but it enables free transpiration of steam.
- This product can be water-diluted, it is solvent-free and it does not exhale vapours during its application resulting in reduced harmfulness for the environment and the users.
- When RESICOLOR 440 impregnation are compared with acryl or wax-based treatments, they display enhanced mechanical and chemical resistance features and last longer in time.
- RESICOLOR 440 stops the natural chalking of cement and makes periodical cleaning easier.

The following table illustrates the reduction of the absorption coefficient by means of immersion in water for concrete cubes treated with two layers of product 1:2 water diluted as specified in the How to use section. 48 hours later the non-treated surface has absorbed water three times more than the treated surface.
To reduce absorption even more a third layer of product can be applied or water dilution can be reduced.

Tests carried out pursuant to UNI EN 13755:2002norms (determination of absorption coefficient by means of immersion).
Preparation of the support
The support must be healthy, dry and clean and feature moderate porosity to ensure homogenous absorption of the product.
It is best to remove dust, dirt, stains of oil and any sort of deposits using high pressure water washing to avoid hindering product absorption.More specifically, stains of oil and fat can be cleaned using RESISOLV 130 or using 1:10 solution of soda and water followed by rinsing with clean water.
Wait for the surface to dry out, because RESICOLOR 440 penetrates more easily in dry supports.
If oil and fats happened to have deeply impregnated the support, scarify and restore using a RESICEM series mortar.
Preparation of the support
Pour component B into component A and Blend at slow speed for 3’ – 5’ using drill with helix/spiral to reduce air inlet as much as possible. Slowly add clean water with continuous agitation until a white, lump-free latex is achieved.
Recommended dilution
A+B+WATER=100+200+600
Application
Brush, roller of low-pressure spray apply. Remove excess material in hollows and dips and let it dry out.
After 12 – 24 hoursapply a second layer of product using the same method.
To avoid stains and glossy areas, do not apply excess material.
Notes
Apply with temperatures between +5 and+35 °Cand only on cured concrete.
By pouring B component into A component, the hardening reaction starts: following mixture the time available is limited and it depends on the temperature.
Due to the imbibing nature of the product, when it reaches the dry dust free condition the surface may be painted again.

Complete hardening: 7 days.
Consumption varied based on the porosity and waterproofing characteristics you want to achieve.
For increased impregnation and waterproofing the product may be applied with different A +B + water ratio or by applying three layers instead of two with product diluted as recommended in the how to use section.
Dry shake industrial floors:60 - 80g/m²per layer of non diluted product which correspond to 180 – 240 g/m2 of diluted product as per recommended ratio.
Available in packages (A + B component) of 6 kg and 15 kg.
If stored in a dry and sheltered place, RESICOLOR 440 remains unaltered for 18 months when kept in its original sealed containers. Keep from freezing.
- Anti-dust treatment of new and old cement floorings in environments where the presence of dust is harmful, i.e. in case of food storage, warehouses where items of clothing are stored, electronic industry departments, data processing premises, etc.
- Protective treatment of cement industrial flooring to enhance resistance to abrasion, waterproof the surface and make it moderately resistant to the aggression of diluted acids and bases, oils, gasoline and solvents.
- Strengthening by means of impregnation of the superficial layer of porous building materials like concrete, plaster, brick, calcareous stone, tufa, etc.
