TECHNOLOGY ACID ETCHING OF CONCRETE 
(English ACID ETCHING)

Acid etching involves treating concrete surfaces with a special acid gel.MICROGEL®  followed by rinsing with surface treatment with water. The acid gel reacts chemically with the surface laitance, dissolving it and allowing it and other water-soluble contaminants to be washed away with plain water. Thus, if your mixture contains a decorative filler of a small fraction (0-2 mm), you can expose it on the concrete surface, visually creating the effect of natural stone.

However, etching (or washing) concrete with an acid gel has additional functions: it opens the pores of the concrete and prepares the surface for further processing. Although concrete can also be prepared by hand by sanding it with a grinder, acid etching is generally much less labor intensive. Creation of logos, drawings and inscriptions on concrete surfaces can also be realized using acid gelMICROGEL® and etching techniques.

CREATING STRETCH CONCRETE SURFACES

The acid etching technique, with a certain composition of the mixture, makes it possible to expose fine stone filler (sand) on the concrete surface, thus, with minimal effort, concrete products can be given an exquisite texture of natural stone. Thanks to its gel-like consistency, light and precise application,MICROGEL®creates evenly etched concrete surfaces, and is suitable for processing vertical surfaces such as building facades, outdoor furniture, steps and columns.

CREATION OF LOGOS, DRAWINGS AND SIGNS

In the process of acid etching in places where the acid gel is appliedMICROGEL® a thin layer of cement is removed from the concrete surface. Thus, using vinyl stickers, we can create a variety of drawings and patterns on concrete, brand our products.

To do this, a sticker made of a waterproof material is applied to the hardened concrete surface, with a pre-made plotter cutting of the pattern, and then the places not covered by the sticker are processedMICROGEL®. Upon completion of the reaction, the surface is washed off with water, the sticker is removed and we can admire the resulting pattern.

INCREASING ADHESION AND PREPARING CONCRETE FOR COATING

Raw concrete surfaces may be too dense or smooth for a good adhesion of paint or protective impregnation. In this case, the use of acid etching technology is a simple and affordable solution to improve the level of adhesion of the treated concrete surface.

 

In order to seal the concrete surface, protect it from oil and food contamination, fungus, mold and give it a silky sheen, we recommend treating it with a special protective coating.COLORFRESH Intensive, which works 3-5 years on horizontal surfaces and more than 10 years on vertical ones. 

ANTI-SLIP EFFECT  

An additional advantage of concrete using the "Acid Etching" technique is that, due to the rough texture, it is extremely difficult slip. Thus, in some cases (for example, when constructing ramps, railway slabs, steps), the use of this technology is simply necessary and creates the safest coating for concrete elements.

Apply

Apply acid gelMICROGEL® on a concrete surface pre-moistened with water  

Wait

Maintain reaction timeMICROGEL® with concrete surface (until bubbling ends)

wash away

Clean the surface with a directed water jet, using warm water if possible.

Ready

The acid-etched concrete surface is ready.
