Is there any information about using this product on a cinderblock saltwater seawall that has efflorescence issues?
Silacote Paint
We have a waterfront property that has a cinderblock seawall. I’m looking for a product to cover this wall, mostly for asthetic reasonings. I would like to know if there are recommendations for preparing the wall for the coating as we have efflorescence issues. Also how will
The coating respond to efflorescence after applied? Are there any gallery images of a seawall being coated with this product? Thank you!

According to the manufacturer, our Silacoat Paint can be used for a seawall. This product is highly durable because it chemically bonds with the concrete block. It will protect the seawall and help control efflorescence but will not stop it completely. For that you may need a waterproofing membrane on the other side of the seawall to stop the migration of the salts that penetrate through the block. Applying 3-4 coats of our AFM Dynoseal would be useful on the backside. It is designed for below grade applications for foundation walls and will act as a moisture barrier below the ground. It is black in color which may not suit your aesthetic requirements if exposed.
