Making bitumen primer in two ways - manual video

Primer called up, which is treated with any surface prior to finishing.In fact - it bituminous primer.Often under the finish meant painting.The use of this material significantly increases the "coupler" with a surface coating (adhesion) to prevent moisture absorption.

bituminous primer - composition obtained by dissolving the oil bitumen.The construction is often used to improve the reliability of the waterproofing layer, such as device roof floors (after laying the screed).It is sold or in concentrated form, or a ready-to-use.However, this material is quite possible to make their own hands.There are two methods, and the use of one or the other depends on the availability of time.

first method of manufacturing a primer

It is used when "not tolerate" time.Get a composition method "of cooking."It is necessary to take into account, for the treatment of the material is prepared primer.The components of the mixture are bitumen and petrol.

following ratio:

• for the treatment of metal surfaces - 1: 3;
• for concrete pavement - 1: 2.

sources of fire can be very different: blowtorch, kerosene stove, fire.The main thing that inherent in the capacity of a material to bring to a boil.After that, the liquid bitumen gently, slowly, is poured into the tank with gasoline.

Important!It bitumen gasoline.In no case do the opposite !!!

remains only a good mix, and you can start priming.

second way

ready to get up, you will need a lot of time - from 7 to 12 days.In the prepared container calculated in proportion poured petrol.Then to put the pieces of the bitumen.And yet - it will start to slowly dissolve in gasoline.

However, we must take into account two factors:

• container must be tightly closed.Otherwise, gasoline vapors will evaporate;
• to accelerate the process of preparation of the primer must be regularly thoroughly stir the whole mass, and is more a waste of time.

Recommendations

• desirable to prepare a primer immediately before use, as it thickens over time;
• its temperature when used should be about 80 degrees.If the composition is cured, it must be heated and mixed thoroughly;
• temperature at which begins to solidify primer - 15 degrees.Therefore, for the storage you need to choose a warm room;
• composition is applied to the treated surface by brush, roller, brush;
• avoid freezing material, as its properties deteriorate significantly;
• excludes all other "solvents" except gasoline (eg, diesel fuel);
• work with bitumen primer can in rainy weather;
• applied composition must dry thoroughly (at least 16 hours).

Keep in mind that the resulting composition is classified as flammable materials, and therefore need to store it accordingly, and to comply with the security measures.
