How Do You Acid Stain An Interior Concrete Floor?

Here is how to acid stain an interior concrete floor;

Prep The Surface

Some preparation is essential to guarantee that you have the finest coverage possible. You may need to use specific cleansers such as degreasers, paint, or mastic remover after cleaning with detergent.

Spray And Apply Stain

Test a sample in an inconspicuous location before applying the stain to determine the number of applications required to create the desired appearance.

Then, using a handheld airless sprayer, apply the acid-based stain. Because the acid will corrode any metal parts, make sure the sprayer is mostly made of plastic.

It should be sprayed evenly throughout the floor. While spraying the stain, have someone behind you with a broom work the stain into the floor.

This will result in a more consistent finished product. Allow the first coat to dry according to the can’s directions.

Brushstrokes may show, so go over the floor with a second coat to hide them.

Clean The Acid Residue

Before applying the sealer, all acid residue must be removed. Apply the sealant using a separate pump sprayer than you did for the stain.

Spray the floor with a neutralizer made of 4 parts water and 1 part ammonia. Allow it to dry completely.

Then, wipe the floor with clean water and suck away any surplus water with a shop vacuum. Before sealing, the floor must dry overnight.

Apply Sealant

Add the sealant when the neutralizer has cured. To uniformly apply it onto the floor, use a paint roller with an extension pole. Use a synthetic roller for the smoothest application. It is advisable to apply two coats of sealant.

Please keep in mind that you’ve previously cleaned and removed the old sealer, so simply follow the Apply the Sealer instructions.

Allow To Dry

Before stepping on the floor or restoring baseboards or furniture to the room, make sure it is entirely dry.

How Do You Apply Eagle Concrete Stain?

Before beginning an application with any EAGLE product, always assess the appropriateness and desired finish on a tiny test area.

When applying to a test area, utilize the same surface preparation method and equipment that you would use to execute the whole general application.

Prepare The Surface

The most critical phase in an ACID STAIN project is surface preparation. The concrete should be at least four weeks old, clean, and free of dirt.

Do not use muriatic acid to clean since it may damage essential minerals required to generate the appropriate hue.

Remove any debris, wax, grease, oil, or other impurities that may obstruct the sealer’s adhesion to the surface. This involves the removal of any previous coatings (for instructions on removing old sealers, click here).
Eagle cleaner degreaser & neutralizer should be used to clean greasy concrete. For extremely oily areas, use a medium to a hard bristle brush.
The concrete must be porous enough to allow water to pass through. If the concrete surface is smooth (as on a garage floor or interior floor), the substrate must be etched using EAGLE ETCH & CLEAN. Dense concrete surfaces may require mechanical preparation before the sealer can be applied.
Pressure wash. Always use a pressure washer with a pressure range of 2500-3000 psi to thoroughly rinse outdoor surfaces. After pressure cleaning, allow 24 hours for the concrete surface to dry thoroughly. Ensure that interior floors are completely washed.
Using masking tape and paper, mask any nearby surfaces you DO NOT want discoloured for overspray. This includes the flooring and the walls. To avoid bleeding, use duct tape over masking tape.

Application

It is best to use an EAGLE ACID RESISTANT SPRAYER. Dampen the concrete with water before applying the acid stain, but do not puddle it.

Spray in an overlapping motion, keeping a moist edge until the entire surface is coated. Allow at least 6 hours for ACID STAIN to react.

It is entirely 0k to apply EAGLE ACID STAIN one day and then begin the cleaning step the next. To approach the final hue, properly clean the debris and pour water onto the floor. Apply a second layer of Acid stain if deeper color is needed.

The concrete must be completely neutralized. Using an acid-resistant synthetic bristle brush, remove debris from the floor with Eagle cleaner degreaser & neutralizer. Repeat. Rinse with clean water and mop up any excess.

Indoors, a Wet-Vac might be useful. Rinse with clean water until the rinse water is colourless. Concrete must be fully residue-free. Expect to rinse multiple times with clean water.

When the concrete is dry, wipe the floor with a white cloth to see whether it is ready. If there is any residue, rinse and dry again. Repeat until no residue is left.

Cleanup

Water is used to clean instruments.

Maintenance

Only use water to clean the sealed surface. To avoid sealer accumulation, reseal the surface as needed, but no more than every two years.

How Do You Use H&C Colourtop Concrete Stain?

When applying H&C Colourtop concrete stain, the air and surface temperatures should be between 50 and 90°F. If the surface temperature surpasses 90°, spray a thin mist of water to cool it down.

For the next 24 hours, no rain should fall. H&C® Concrete Stain Solid Color Water-Based should be applied to dry or slightly moist surfaces.

To guarantee color consistency, combine all containers. Thin your initial application of stain for bare concrete with one pint of water per gallon of stain.

This phase is not required for asphalt, previously painted, or vertical surfaces.

Apply the first application evenly and in one direction. Allow at least 2 hours for the first coat to dry before applying the second coat. The second coat should be applied opposite to the first coat.

Two coats are generally plenty. In the final coat, consider applying H&C® Sharkgrip Slip-Resistant Additive.
