Anything we think about pasting is a thing of the past if our priority is to save costs when we get something in the build direct. Now there is a more practical option that apparently saves us time and money in less than what you say its name: Dun dun.
The conventional glue system requires more personnel to build: a bricklayer and two assistants to settle 800 bricks in a day, with the mass of Brazilian DunDun origin, will only require a mason and an assistant can raise 2,500 bricks at the same time .
Its strong, resistant and practical nature is due to the mixture of polymers that is considered the evolution of the cement since only the application of two cords of 1 cm of diameter each one, on the bricks and blocks, obtains the same effect that with the traditional mix and reduces to 95% the necessary inputs, since it does not require water, light, sand, lime, cement or mixer.
Open and Ready
The application is as simple as making a cake. The package containing the DunDun is shaped like a sachet. By cutting the tip of the content wrapper, it becomes a space of pastry utensil that allows to apply the product in a simple and clean without having to work more at the time of cleaning. It is the ideal material for all bricklayers and for homeowners who want their work to come out with the greatest speed and with great quality since they will not have to make the old mix when lifting a wall.
Its handling makes it easier to store and transport inside the work, generating less waste and increasing the speed and efficiency of work, a characteristic to which its waterproofing is added.
Cheap, too cheap
It is so profitable that for the skeptics you can draw the bill. The product yields 20 times more than the common blend: three kilos of adhesive equals 60 of traditional cement mix.
And although everything seems to be as perfect as possible you have to soak up as much information as you can before opting for this mix, it does not mix with everything. Dun dun can not accommodate very large differences between one block and the other, which can occur when used with blocks or low quality bricks. In addition, the adhesive is not suitable for structural masonry. For the norms in force for the execution of this type of walls were designed for cement mortars and require a centimeter of thickness in each joint.
But there is no need to worry, it has more benefits than obstacles when we think of building part of our own home, office or any place that welcomes us.
