NovaTuff P-505 Epoxy Primer

Tikweld welding supplies and services is the distributor of NovaTuff Epoxy Primer in Nigeria. NovaTuff P-505 is a polyamide epoxy primer designed to penetrate and seal concrete surfaces, leaving a smooth, pinhole and bubble free surface. The formulation includes a long pot life as well as a low sensitivity to substrate moisture, allowing it the ability to bond when applied to a damp surface.

Resistance:

NovaTuff P-505 has excellent resistance to various solvents, hydrocarbons, acids and alkalis, particularly food acids.

Preparation:

To begin, the surface should be etched to provide a profile or “tooth” for optimal adhesion.  Surfaces must be cleaned free of grease, oil, wax, mastic compounds, paint, waterproofing compounds, form release materials, and all other contaminants prior to application.

New concrete and masonry should not be coated for at least 28 days to permit the concrete or mortar to cure and dry out.  Concrete should be visually inspected and tested for moisture content before coating.

NovaTuff P-505 will not develop optimum adhesion to concrete unless Latinate and other loosely bound materials are first removed from the surface.  Latent must be removed by abrading.  Shot blasting, scarifying, grinding, sand-blasting or other abrasive mechanical means are recommended.  Acid etching is an option but not recommended because of environmental concerns or accidental damage to non-target areas.

Mixing:

The mixing of parts A & B is very important!  NovaTuff P-505 has a mixing ratio of 3 parts “B” to 1 part “A”.  Use a power mixer to thoroughly combine both parts. Mix for a minimum of one minute per gallon. Allow idle activation time for a minimum of 15 minutes.

APPLICATION:

Brush, 3/8″ nap roller cover, squeegee, or airless spray equipment may be used to apply NovaTuff P-505.  Surface configuration, weather, or area surroundings will dictate application method.

Dry Film Applications:

DO NOT apply product heavier than 100-sq. ft. per gallon per coat.  For a heavier dry film, apply necessary number of coats.  Use of thinner increases possibility of sag and reduces dry film thickness.  NovaTuff P-505 may be applied to damp surfaces but it is best to have a dry surface if possible. Allow NovaTuff P-505 to become tack-free before applying additional coats or approximately 6 hrs.  Caution!  Without the use of aggregate in NovaTuff P-505, the surface will be slippery when wet!

GENERAL:

NovaTuff P-505 should be applied in well-ventilated areas.  Surfaces should be free of foreign matter. DO NOT apply product near an open flame.

CLEAN UP:

Application equipment should be cleaned immediately with Lacquer Thinner.  Use Apple Cider Vinegar to clean hands and skin.  Do not allow NovaTuff P-505 to remain on tools!  Once it sets and is cured, it is difficult to remove.
