Application of staining process to the concrete involves many steps such as:
- Preparation of the surface
- Application of the stain
- Removal of residue
- Application of sealer.
Preparation of the surface:-
The concrete that you are about to take up in the staining process, whether it is old or a new concrete, requires exhaustive preparation of the surface. In the case of coatings and paintings, the opaqueness of the paint could hide many flaws. But the stains caused through acid are translucent. If there are any remains of garbage deposits on the exterior of the concrete, it is prone to be visible in all probabilities even across the freshly coated stain. When this work is executed in the proper fashion, this first step has a dramatic effect on the final appearance of the area. Preparing the surface could be made in either of two ways, one of which is to grind mechanically and the second is to use an exclusively formulated cleaner. This is always available with the manufacturer of stain. For all your Staining requirements, concretestampingandstaining.com will be your best destination.
Applying the stain:-
After cleaning the concrete, it is the right time for the application of the actual stain. The following steps are to be followed:
- You must first mask the area in order to save the walls, door frames etc.
- You must dilute the stain with enough water to the required and desired consistency. You may refer your manufacturer’s suggestions for specifications.
- Now you must brush the first coating on or spray it depending on the specifications. For doing this, you have popular sprayers including HVLP sprayers, pump sprayers, production guns, trigger spray bottles, airless sprayers etc. A sponge or brush can be used in cases which require absolute control of the stain application.
- The freshly applied stain must be left to dry up. The duration of the drying time depends on the air flow, humidity and temperature. In favorable conditions, the concrete could be left to dry up for fifteen to twenty minutes. Anyhow, the total curing time is twenty four hours.
- You will have to repeat the process if you require more color intensity. Many stain manufacturers suggest waiting for a few hours in between applications.
Removal of the residue
Soon after the stain had been applied, cleaning up is required. Following is a standard cleaning up process.
- You have to rinse up the concrete with crystal clear water until the water is back to being clear.
- Now you have to neutralize the stain with ammonia, baking soda or TSP. This would be necessary only if you are using an acid stain. Neutralization is not needed for water-based stains.
- You have to use a brush that is soft bristled or a broom to loosen up any residue that is stubborn before the final most rinsing.
Adding a protection coat
After you allow the stained concrete to dry up overnight or if necessary longer, now you can apply sealer of your choice. Many stain manufacturers suggest application of two coats of sealer to obtain the best durability. The sealer type to use would depend on whether the concrete is outdoors or indoors and the level of gloss that is desired by you.
