APPLICATION METHOD

In general, you should take the following factors:

• repair the surface (fill in depressions, eliminate unevenness, eliminate any old waterproofing, etc.)
• singular points preparation(perimeter, sinks / evacuations, expansion joints or structural)
• clean up the surface or substrate, removing any dust, dirt, grease or efflorescence.
• remove any silicone based products
• the surface has to be enough compressive strength of adhesion of the membrane. If it were not so, we will proceed to apply our primers resins to achieve this target
• adhesion tests may be required for certain substrates
• in general all surface preparation requires the removal of all grease, dirt loose and flaking materials prior tp the application of Tecnocoat P-2049
• the pull off strength of the membrane will be minimum  217.56 psi (1,5 N/mm² / 1,5 MPa )
• in case of dubt of all above, apply before in a restricted area and to check

The TECNOCOAT P-2049 pure poliurea system can be applied to many different surfaces and the procedure will vary depending on its nature or state. Below we set out some of the application for the most common surfaces; for other surfaces not described, please contact our technical department.

Concrete substrate

• any depressions or voids should be repaired using our epoxy resin mortar: mix (ratio of ±1:4) of epoxy resin PRIMER EP-1020 with silica sand.
• the concrete should be completely cured (concrete curing takes 28 days) or, in any case, the maximum level of humidity allowed for the substrate should be verified, depending on the primer used.
• any concrete laitance or release agents should be eliminated and an open pore surface achieved by grit blasting, milling or sanding (to achieve a Concrete Surface Preparation index -CSP- 3 to 6 from ICRI Guide 03732, depending of the final use)
• on old concretes, some acid etched is needed to open the pores for primer acceptance
• clean up and eliminate all contaminants from the elements, such as dust or particles from the previous processes.
• apply the primer in the conditions and with the parameters indicated in the technical specifications for these products. In general, the dual component polyurethane PRIMER PU-1050 should be used, to promote adherence to the concrete surface, reduce the pinhole appearance, and absorption of moisture in the substrate ( please check the primers absorption capacity in the TDS )
• apply the TECNOCOAT P-2049 pure polyurea coating.
• application of the aliphatic polyurethane resin TECNOTOP S-3000/2C/2CP, in consumption and desired thicknesses in the case of no protection against UV rays. This application can be done by short hair roller type equipment "airless" (consult the TDS of these products before the  use)S)

Ceramic substrate

• ceramic surfaces should not have empty joints or loose elements or parts. These should be filled with MASTIC PU mastic, complemented with TECNOBAND 100 on the joints if necessary.
• for rapid and efficient cleaning of the surface use pressurized water and check that it evaporates completely. Also verify that all dust and other physical contaminants have been eliminated.
