What are concrete hardeners?
Concrete hardeners can be made of various ingredients. However, the most common ones include soluble silicates, epoxy, resins, and other reactive ingredients.
Sometimes these mixtures come in a one-part solution, while others may come with a 2-part resin and hardener mix. In silica-based hardeners, the silicate in the solution penetrates the concrete surface and hardens to form a solid, dense insoluble mineral.
Once it’s dry, it’s twice as hard as concrete and moisture and corrosion-resistant. This is why you’ll typically see hardeners used on concrete floors in manufacturing plants, restaurant kitchens, and hospitals.
These environments generally are traffic-heavy, and concrete hardeners are often recommended to improve the resilience and durability of the floor.
Hardeners can be specified based on the type of traffic a floor receives, with some recommended for light, medium, and heavy-duty areas.
How do you use concrete hardener?
Before applying a concrete hardener, it’s essential to prepare the floor surface. It’s that the concrete floor is structurally sound and thoroughly cleaned before applying a hardener.
This means removing any contaminants, sealers, oils, curing compounds, or other materials that may have left a residue on the floor surface.
It’s also important to steel and repair any holes or cracks in the concrete to prevent any deteriorated areas on the surface before the hardener is poured.
The application method will vary depending on the type of hardener that you use. For resin-based hardeners, you’ll typically need to mix the resin with the hardener and then pour it onto the surface for it secure.
Many of these hardeners are self-leveling, meaning that you won’t need to use a concrete placer to level the solution after it’s been poured.
Other solutions may need to be diluted with water before they can be poured, while others are ready to be poured immediately.
The cure time of the hardener will vary, but it will typically range anywhere from 30 minutes to a few hours. It’s always recommended that you let the surface cure for the recommended time and wait a few days before allowing foot traffic.
What does concrete color hardener do?
Concrete color hardener works the same way as regular concrete hardener with the addition that it adds pigment and/or texture to the concrete surface. This allows you to blend the surface color into the decor of your home or business.
For example, if you want the floor to have an orange tint, you can mix the necessary pigment with your concrete floor hardener to create the look.
How do you use concrete color hardener?
It depends on the type of color hardener that you use. Some hardeners come ready for immediate application, while others will need to be mixed with the pigment before being applied to the concrete.
As with any hardener, you’ll need to prepare the concrete floor ahead of time by cleaning it and removing any other debris. The color hardener will also need to set and cure before the floor is ready for traffic.
