Teifoc brick construction sets can be reused multiple times. To dissolve the mortar and recover all materials, simply soak the structure in water for a few hours. After that, let the bricks dry a bit, and you can start again with new mortar. The brick sets can be combined with each other. The whole family has a lot of fun with the Teifoc brick construction set. Teifoc bricks are made from natural materials. The clay is shaped, dried, and then fired using special machines, just like real bricks used for building houses. The mortar is a mixture of fine sand and corn extract. To prepare the mortar, mix 3 heaping tablespoons of mortar powder with 1 tablespoon of water to form a smooth paste. Use the trowel to coat each brick with enough mortar and press it firmly. Remove any excess mortar with the trowel.
