Concrete Densifier

Concrete Densifier

How do you know when to employ a chemical hardener?. All the concrete is different, and it is best to assess each substrate before you employ a densifier. Some say that the only time to employ chemical hardener is throughout the polishing phase after the stainor dye was implemented, as well as after the 200 grit resin bond diamond has made its passes. The logic behind this is that by applying the densifier from the order, the color will be locked in. This can be true with regards to hard concrete, however, it isn’t the exact same for soft concrete.

Based on the desired end, with gentle to moderate concrete densifier may be implemented after the diamond of 80 gr. And after that doing the following chain of grits. With moderate tough concrete densifier can be implemented about the 200 to 400 grit range. The level of hardness ought to be determined prior to beginning any jobs and may be done.

Though densifier can be implemented after grinding with 80-grain metal binder diamond it may be successful to use the densifier to concrete after color has been implemented, which can be around 400 grit. Timing varies with regards to applying densifier to concrete which will be dyed or acid stained. When utilizing dyes the dye could be implemented after the densifier because they’ll penetrate easily because of their solubility. Dyes don’t require a chemical reaction to work, but acid stains do. When utilizing acid stains, the densifier is best applied after the stain has been implemented, rinsed, and neutralized. That is due to the densifier producing a bacterium which can prevent the penetration and reaction of the stain.

Probably the most crucial thing to contemplate when applying a densifier are to realize the concrete itself. The kinds of densifier are made from potassium, sodium, and lithium silicates, along with the newer kind of nanotechnology and colloidal silicate. In general, a silicate is a silicate and potassium, sodium and lithium are the supports of the silicate that delivers the densifier that allows it to respond with the concrete.

The exact chemistry of densifier function is complicated, but silicates respond with the remaining calcium hydroxide in concrete, which stems from the hydration process. Adding the silicate into the structure and capillaries of the concrete creates a substrate that’s impermeable with a coating which is less predisposed towards dusting.
