PART 3 -  EXECUTION

3.1              EXAMINATION

A.         Comply with Section [01 70 00] [__ __ __].

3.2              SURFACE PREPARATION

A.         Prepare surfaces in accordance with manufacturer’s instructions.

B.         Surfaces shall be clean.  Remove dust, dirt, oil, grease, chemical films, coatings and other contaminants before application.

C.         If surface does NOT absorb water, then there is possibly another sealer applied to the surface and sealer should not be applied.

D.         Exterior Surfaces: In all cleaning cases rinse well using 3000 psi pressure washer and allow to dry thoroughly before application.

E.          Interior Surfaces: use a wet vacuum to remove excess water.

3.3              APPLICATION

A.         Apply sealer in accordance with manufacturer’s instructions.

B.         Stir material thoroughly before and during application.

C.         Back-roll to even out the material and to remove any puddles in low spots.

D.         On some historic, old and extremely porous surfaces a second coat of either plain Trojan or Trojan Color may need to be applied to completely seal the surface.

E.          Surface minimum temperature must be above 45 degrees F before application.

F.          Allow to dry thoroughly before traffic is allowed onto floor.

G.         Trojan Masonry Sealer: To paint over a Trojan treated area use only a good quality acrylic, oil-base, epoxy or urethane paint. Do not use latex paint over a Trojan coated surface since latex paint makes a weak bond especially in exterior applications. On new Concrete, Let dry and cure for 21-28 days depending on temperature and humidity.

H.         Trojan Color Sealer: should not be applied to a hot surface in the sun. Flash drying will occur and the affect will be uneven color with overlap marks. Always maintain a ‘wet edge’ when applying this product. On new concrete, (under 2 years of age), a pH reading should be taken before starting application to be sure that the pH is between 6 & 8. If it is not, then Enviro Etch should be applied to the surface. Rinse and allow to dry and re-take the pH reading. 

1.       All interior surfaces must use Enviro Etch first to allow for adequate and even absorption of the Trojan Color Sealer.

2.      Apply Trojan Color Sealer with a low-pressure sprayer. Trojan Color Sealer should be applied liberally to allow the surface to drink as much as possible without leaving puddles.

3.4              SAFETY

A.         Safe storage, handling and use dictate that adequate health and safety precautions be observed with this product. User is specifically directed to consult the current Material Safety Data Sheet for this product as well as precautions contained on product labeling.

3.5              PROTECTION

A.         Protect sealer from damage during construction.
