SITE PREPARATION

  • The substrate must be structurally sound, solid, level, clean, free of dust, loose particles or any substance that interferes with adhesion;
  • The concrete must have at least compressive strength of 3.600 psi (25.0 MPa) and It should be adequately cured and residual moisture < 4.0%;
  • The concrete must be without imperfections and irregularities. It is important a good surface finish to achieve optimum performance;
  • The substrate temperature must be between 41° F to 95° F (5 ° to 35 ° C) and the air relative humidity less than 85%.

 

PRODUCT PREPARATION

  • First mix the components separately;
  • Launch the B component in the Component A and mix for 2 minutes with the aid of a mechanical mixer; The application time is 50 minutes, whereas at room temperature;
  • Never add solvent, water or any chemical compound in the mixture;
  • To avoid mistakes , the BAUTECH MEGA POLYUREA must be mixed thoroughly, do not mix fractions of a kit.

PRIMER APPLICATION

APPLICATION ON CONCRETE OR MORTAR BASE

1.1 GROUNDLEVELORUNDERGROUND

  • For applications on cement surface in contact with the ground, it is recommended that a waterproofing must be done with polymeric mortar preceded by a crystallisation process for inhibiting the presence of moisture by capillarity and provide a smoother surface for the application of polyurea, which must be carried out 7 days after application of the polymeric mortar.

1.2 ABOVEGROUND SLABS APPLICATIONS

  •  For applications on cement surface above grounds, it is recommended using a polymeric mortar to provide a smoother surface for the application of polyurea, which must be carried out 7 days after application of the polymeric mortar.

2 APPLICATION ON METAL TILE

  •  For applications on metal tiles, it is recommended that the preparation of the base is accomplished with application of a paint epoxy primer, all voids must be filled in order to avoid the formation of bubbles in the coating, if necessary apply two coats. Wait no more than 24 h for the application of the BAUTECH.MEGA POLYUREA. If the period of 24 hours is exceeded, you must sand the site before proceeding to the next step. Clean all tools and equipment beforehand and afterwards.

PRODUCT APPLICATION

  • Apply BAUTECH MEGA POLYUREA using smooth metal trowel in one coat; For vertical applications use Spray system, solvent resistant paint roller or brush. For outdoor applications that require aesthetics, apply a polyurethane paint as the final layer, due to BAUTECH MEGA POLYUREA has no color stability. For questions please contact our technical department by email sac@bautechbrasil.com.br
  • For special applications the minimum temperature for the product installation is 41°F (5°C), so the temperature should be kept for 3 days greater or equal to this average, and then submits it a temperatures negatives.
