RESICOLOR 451
EPOXY PAINTING IN WATERY EMULSION FOR FLOORS, WALLS AND CONCRETE SURFACES
Semi-gloss coloured epoxy enamel, in aqueous emulsion, odourless, good abrasion resistance; breathable and vapour permeable.
Used for painting floors and walls of civil and industrial buildings.
RESICOLOR 451 is a dual-component epoxyenamel which is very pleasant to look at. It features good mechanical strength to wear and tear, moderate chemical resistance to low concentration of basic and acid solutions and good resistance to oils and fats.
Compared to standard painting, RESICOLOR 451 offers the following advantages:
- Excellent adhesion to concrete, bricks and stone;
- Waterproof against liquids but lets steam through;
- It can be varnishes with epoxy, polyurethane and acrylic products;
- It makes cleaning the surfaces easier and enables use of washer-drier machines or high pressure water jet cleaners;
This produces features low risk for the environment and for its users because it is in watery emulsion and it is solvent-free; it does not release harmful vapours and its tools can be easily cleaned with water after use. It can be applied in those environments where use of solvents is not recommended or it is dangerous, i.e. enclosed buildings or with insufficient ventilation or in environments with risk of sparks;

RESICOLOR 451 features good resistance to occasional contact with low concentration acid and basic solutions, but in case of permanent contact. Dumping of solutions made with most organic and inorganic acids and solvents (methanol, benzole, toluene) must be promptly removes (cleaned and neutralised).
Preparation of the support
Floors
The surfaces to be coated must be compact, crumbly-part grout and cement cradle-cap –free, clean and with no oils, fats or waxes. Cracks, cuts or small millings must be stuccoed with epoxy adhesives like RESICOL 100.
The product can be applied on dry or damp concrete floors following washing with washer-dryer.
For better adhesion, the surface must be slightly roughened with diamond or silicon carbide wheels. Then remove any traces of dust or dirt using an aspirator. In case of closed and compact surfaces like dry-shake industrial floors, acid washing (5-10% hydrochloric acid) is recommended following sand-paper with consequent washing and neutralization.
Walls
Very porous concrete walls or with cracks and omega cavities must be levelled in advance with RESICOL 100, epoxy adhesive or with RESICEM 712, cement bi-component smoothing agent. Plasterboard must be treated in advance with an insulating agent like RESICOL 170, a single-component acrylic primer.
Preparation of the product
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; during this operation, carefully scrape also the bottom and the sides of the package.
In the event of partial use of the package, the two components must be carefully weighed in weight (not in volume) following the ratios on the label.
Application
Brush, roller or airless spray apply, in at least two layers, with average consumption per layer of 100-200 g/m2. The first layer must be diluted with 5 – 10% water to improve product penetration in the support. The following applications can be made with no dilution.
On plasterboard application use the product as it is.
Note
This product cannot be applied on surfaces soaked on water, with puddles or superficial coating. Apply only after the concrete is cured. Do not apply on fine mortar or lime-based plasters. Clean tools with water. Wear gloves, protective suite and goggles. In case of contact with the skin, eyes or mucosa, rinse immediately with water and soap for 10 – 15 minutes, then seek medical attention
By pouring B component into A component, the hardening reaction starts: following mixture the time available is limited and it depends on the temperature
| Temperature | Time of use or pot life | Dust free tack free | Paintable again after | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 10 °C | 150 min | 10 hours | 20 hours | |||||||||||
| 20 °C | 100 min | 7 hours | 15 hours | |||||||||||
| 30 °C | 50 min | 4 hours | 10 hours |
Complete hardening occurs after seven days with a support temperature not below 10 °C.
After at least 48 hours from application have gone by, it is necessary to sand the surface with abrasive retina disc (120 grain), before proceeding with painting
