What is the best procedure to remove leached minerals from surface of newly laid brick?
I had to soak these very porous Mexican fired adobe brick before I could mortar them in place, or else dry, they would immediately suck all the moisture out of the mortar. Here is a picture of two brick columns I’ve finished. The one in the background was the first one done and is showing the most leaching of minerals/ salts.

I called the building supply place I bought the brick from and they said apply an 8:1, water: muratic acid, wash with a bristle brush, and wait for bubbles to stop.
My questions are,
1) How long to I have to wait to apply the muratic acid wash? Until the bricks dry?
2) I have not filled the core with concrete yet. Should I wash the brick before or after I fill the core with concrete?
3) After the bubbles stop, do I then rinse the muratic acid compound off with a water hose? This seems to make sense, because I will be applying sealer to the brick after they dry and cure, and maybe traces of the acid remain if I don’t rinse?
Thank you for all your help!
It’s called "efflorescence." Fill it with concrete first then acid off the efflorescence and hose the whole thing off. Wait for a bit so that it can dry, then seal it.
How to Care for Concrete Countertops
Concrete countertops are gaining popularity as people are discovering the versatility and durability of this medium. Advances in masonry, like concrete staining, can transform a drab gray surface into a work of art . While caring for your concrete countertop is not as straightforward as a quick swipe with a sponge, it is fairly easy once you know what to do.
Concrete is a mixture of cement, water, and other chemicals which make it very durable, but by nature, also very porous. The manufacturer will apply a penetrating sealer initially to seal the concrete. This kind of sealant actually penetrates the concrete to make the surface water-resistant.
For maintenance, a coating sealer must be applied regularly. These types of sealers leave a coating on the surface of the concrete, that creates a protective film. The sealer should be applied to a clean, dry surface, every several months. Sealers can come in different forms such as a spray, liquid, or wax and can provide different finishes like a natural or wet-look. The manufacturer, a hardware store, or a local concrete contractor can recommend the best kind of coating sealer for your concrete surface.
Other than applying a coating sealer, everyday care of concrete countertops is easy. Clean up all spills immediately and never allow water or other liquids to remain on the countertop for extended period of time. Use a dishrag or sponge—never a scouring pad or anything with an abrasive surface. Mild soap and water works just fine; you should never use bleach or ammonia on your countertop as this can erode the sealant as well as make your countertop look dull.
In the event you have a stubborn stain, this usually means the surface of your sealant has been compromised. Using very fine sand paper, you can rub off the stain and then reapply your sealant. Depending on the kind of finish you have, it’s best to check with the manufacturer first before attempting this.
It may be tempting to cut food directly on your countertop since concrete is so sturdy. However, you should always use a cutting board to protect the surface. While it’s almost impossible to cut the concrete itself, you can damage the sealant. (You will also dull your knife in the process.)
Do not place pots or pan directly from the stove or oven onto your countertop. Use a pot holder or trivet under hot items because the heat can damage the sealant, and extreme heat could even cause the concrete to crack.
Small hairline cracks are common and are a part of concrete’s natural appeal. Many of these will fill in when the sealant is reapplied. In the event you experience a larger crack, they can be repaired, but this is best left up to a skilled concrete contractor.
With just a little maintenance, caring for your concrete countertop is easy. Most importantly, regular sealing will protect your countertop from staining. Simple things like using a cutting board will help your countertop last longer. Keeping just these few tips in mind will allow you to enjoy your countertop for years to come.
