No friend, I didn't paint the brick of my house. When I was building it, I found a cool online store https://brickwholesale.co.uk/bricks/grey-bricks/, where I chose the exact color that suited the style of my house. Are you planning to paint the brick of your house? This is how much paint and strength do you need? It seems to me that it will be easier for you to buy new bricks and lay them over your house. But you think for yourself, this is your life. Good luck.
