Mastic can have different properties andcharacteristics - this is due to various additives in the mixture. Initially bituminous and rubber-bitumen mastics are thick. And for effective use they should be diluted. How to do it right? Let's see how to dilute the bitumen mastic and how to prepare it.
Classification
Each material is classified according to its composition.different signs. Thus, the compositions are divided according to the conditions of use, as well as additives. Mastics differ in technological features. They differ in the possibility of operation at a certain temperature and conditions that ensure the process of solidification and softening.
According to the method of preparation all the compositions are divided intoone- and two-component. Materials from the first group are prepared as simply as possible. The mass can be used immediately without the need to add any ingredients.
Two-component materials are requiredprepare, after that they are ready to use. How you can dilute the bitumen mastic depends on where and how the insulation works will be performed.
What is used for breeding?
Depending on where the material will beapplied, changing proportions and thickness. Otherwise, the composition simply will not be able to remain on the surface before it dries completely. Mastics are different, which means that products for breeding will also be different.
Often used to dilute materials:
- Motor gasoline or kerosene.
- White Spirit.
- Gasoline "Galosh".
In most cases, as a diluentlow-octane gasolines are used. The process of polymerization of the dissolved composition takes 24 hours after application. This is provided that the work is done outdoors.
As for the proportions, they shouldcorrespond to the volume of the applied basis. If you break them, the mixture will dry out more slowly or the fluidity of the solution will increase. As a result, adhesion will decrease or useful properties will be lost. In this case, the material will not bear protective functions.
How can dilute rubber bitumen mastic?There are other materials. This is turpentine, any kind of organic solvents. It is not recommended to use acetone or fluids at its base for these purposes. Some craftsmen dissolve mastic in diesel fuel. As a result, the mixture is heterogeneous. However, this solution is the most quality fills all cracks and irregularities. If the mastic is liquid, it has better adhesion and good insulating properties.
Elastic and special additives in the composition of mastic
Gasoline, kerosene, white spirit are universal.solvents. But choosing what can be diluted rubber-bitumen mastic, the first thing is to decide what characteristics are needed from the solution. Depending on the additives used in the composition, the materials are divided into:
- Bitumen-rubber.
- Bitumen-polyurethane.
- Bitumen-latex.
- Oil and rubber mixtures.
As you can see, bitumen is present in eachmaterial. But supplements are different everywhere - hence the different properties. So, with the addition of polyurethane or rubber, you can get additional elasticity. This is important for most insulation jobs.
Anticorrosive mastic from bitumen with oil
If you add to the composition of the oil, the resulting mixturewill not harden. This is important for the processing of pipes and other metal underground communications. With the addition of oil materials, a sticky, but not tough film is obtained. It will not crack and will be able to maintain its integrity for quite a long time. This solution is not afraid of low and high temperatures. It is an ideal solution for processing heating systems. But for roofing it is not suitable.
Roofing additives
Experts answering the question how to dilutebitumen mastic for the roof, in addition to solvents, it is also recommended to add rubber crumb. This coating will be strong and durable. And it can be applied to any type of surface. The material prepared in this way withstands mechanical loads, shocks and vibrations.
Also for roofing work can be added tomastic and liquid latex in the form of an emulsion. It is nothing like synthetic rubber. The product is extremely simple to prepare and apply, has excellent performance characteristics. The mixture is ideal for roofing.
How to prepare the correct solution
An important point in the process of making mastic -This is a method for applying it to the surface to be treated. It is possible to apply a protective solution both manually and with the help of special equipment. Manual application method is relevant when the amount of work is small. If it is required to apply the composition to a large area, then apply mechanized application methods. On the way in which the mastic will be applied depends on its method of mixing. How to dilute rubber bitumen mastic? Before you start preparing the mixture, you need to prepare the surface on which the composition will be applied.
How to make a primer
The use of primer is a guarantee of reliablegluing materials for waterproofing to porous and non-smooth surfaces. The composition is suitable for priming concrete foundations, cement and sand screed.
For the manufacture of primer will need a cleanbitumen - need a few pieces. Next, the bars are dissolved in gasoline or used engine oil. First, in the prepared container pour the solvent - gasoline or mining. Next, the liquid is heated, and then crushed bitumen is added to the tank.
Conclusion
So, we found out how to dilute the bitumen masticfor the foundation. Construction experts in the process of preparing an insulating material give different tips. So, when using gasoline and diesel lumps may appear. But you need to breed so that the mixture was not too liquid - this entails a large consumption of mastic.
