When sealing our walls we really wanted something breathable to allow any moisture or water vapor to pass through the walls. We experimented with soaking nopal cactus that we had planted on the land for 2 days mixing this with clay and using this a paint/sealer. We only used this for internal walls that would not directly get wet. Nopal Cactus is also a delicious superfood that we LOVE! We also used a silicone based sealer that leaves the walls natural looking and breathable. On the exterior we used an acrylic sealer called 5X1 this is very watery and goes on thin. Good breathability and more protection from water than the silicone or cactus sealer. So far so good the walls are protected!
