About Product:

Dr. Fixit Bitufix is an emulsified thixotropic bitumen protective coating. The coating dries to form a black flexible protective film. The finished film forms a tough barrier to vapor transmission. Typical Applications Dr. Fixit Bitufix is used for providing damp proofing for below-ground concrete structures which are above the water table. The coating is also used as a moisture vapor barrier on block works and concrete surfaces prior to cladding. This can also be used as the protective coating for built-up roofing systems along with fabric.

Method of Application

The application temperature should be between 5°C to 55°C. Application procedures may vary slightly depending upon site conditions. The general recommended guidelines for the application of the bitumen coating is as follows:

1 . SURFACE PREPARATION

The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. } All surface imperfections and protrusions are to be removed and repaired. Structurally unsound and friable concrete must be removed and repaired with a suitable repair mortar or PMM.

2. PRIMING

Primer is always recommended prior to the coating as it not only penetrates into the concrete pores and seals the substrate. It also acts as an adhesion promoter for further coatings. The primer coat can be made on the site by diluting the same bitumen emulsion with 20% water. The primer may be applied by a brush, roller, or airless spray. Allow the primer to dry before any further coats are applied. However, if the primer after the application is left open for more than 24 hours after it becomes dry, clean the surface of any settled dust and apply a fresh coat of the primer.

3. APPLICATION  

Stir the contents of the drum thoroughly prior to application to remove any sediment. The application can be done with a roller, brush or airless spray. Apply the coating at a coverage rate of 1-4 m2/Ltr/ coat, depending on the dry film thickness required. 2nd coat to be applied in a direction perpendicular to the 1st coat.
