NAC TAC, NAC TAC II, and NS97 Primers are necessary components of all NAC Membrane Systems.  The use of the appropriate NAC Primer is required in order to meet the ANSI Specification for shear strength greater than 50 psi as mandated by A118.10 for waterproof membranes, A118.12 for crack isolation membranes and A118.13 for sound control membranes.

NAC Primers

NAC TAC Primer

 

 

 

NAC TAC is a non-flammable, neoprene-based primer for use in interior OR exterior applications. NAC TAC is a pre-mixed formula that requires no thinning, establishes a permanent bond in 48 hours and will not re-emulsify.

 

Application:

Substrate temperature must be a minimum of 65ºF (18°C) for 24 hours prior to application.

 

NAC TAC can be applied with a short nap roller, brush, trowel or sprayer.  Allow NAC TAC to dry until tacky to touch, but non-transferable to finger. This may take as little as 10 minutes, but usually no more than 45, depending upon temperature, humidity, internal moisture level/porosity of substrate and application thickness.  

 

Tile may be set immediately after membrane is installed on horizontal surfaces.  

 

See the label on NAC TAC container or the specified membrane installation sheet for complete application instructions.  Please refer to the Primer Reference chart to ensure appropriate substrate grade for the application.

 

Moisture Vapor Transmission:

NAC TAC Primer will protect against Moisture Vapor Transmission (MVT) when used with NAC sheet membranes providing 10#/1000 SF/24 HRS protection.

 

Coverage:

NAC TAC will cover 375-425 square feet per gallon depending on applicator type and porosity of the substrate.

 

Clean Up:

Remove wet NAC TAC with a damp cloth and plain water.  Use mineral spirits for dried primer.

 

Storage:

Store in original, tightly sealed container in a cool dry area.  NAC TAC has a 12 month shelf life so be sure to rotate stock. Do not store below 35 degrees F (2 degrees C) as NAC TAC is not freeze/thaw stable.  If NAC TAC separates, shake to remix.  If product will not remix, do not use.

 

Packaging:

NAC TAC Primer is available in quart bottles (12/carton), one gallon jugs (4/carton) and 5 gallon pails.

NAC TAC II Primer

 

 



NAC TAC II is a non-flammable, water-based primer for use in interior applica-tions that are on grade or above grade. NAC TAC II is a pre-mixed formula that requires no thinning, establishes a permanent bond in 48 hours and will not re-emulsify.

 

Application:

Substrate temperature must be a minimum of 65ºF (18°C) for 24 hours prior to application.

 

NAC TAC II can be applied with a short nap roller, brush, trowel or sprayer.  Allow NAC TAC to dry until tacky to touch, but non-transferable to finger. This may take as little as 10 minutes, but usually no more than 45, depending upon temperature, humidity, internal moisture level/porosity of substrate and application thickness.  

 

Tile may be set immediately after membrane is installed on horizontal surfaces.   

 

See the label on NAC TAC II container or the specified membrane installation sheet for complete application instructions. Please refer to the Primer Reference chart to ensure appropriate substrate grade for the application.

 

Moisture Vapor Transmission:

NAC TAC II Primer will protect against Moisture Vapor Transmission (MVT) when used with NAC sheet membranes providing 7#/1000 SF/24 HRS protection.

 

Coverage:

NAC TAC II will cover 375-425 square feet per gallon depending on applicator type and porosity of the substrate.

 

Clean Up:

Remove wet NAC TAC II with a damp cloth and plain water.  Use mineral spirits for dried primer.

 

Storage:

Store in original, tightly sealed container in a cool dry area.  NAC TAC II has a 12 month shelf life so be sure to rotate stock. Do not store below 35 degrees F 

(2 degrees C) as NAC TAC II is not freeze/thaw stable.  If NAC TAC II settles, shake to remix.  If product will not remix, do not use.

 

Packaging:

NAC TAC II Primer is available in one gallon jugs (4/carton) and 5 gallon pails.

NS97 Primer

 

 

 

NS97 is a non-flammable, solvent-based primer for use in exterior applications. NS97 is a pre-mixed methylene chloride formula that requires no thinning, establishes a permanent bond in 48 hours and will not re-emulsify.

 

Application:

Substrate temperature must be a minimum of 55ºF (13°C) for 24 hours prior to application.

 

NS97 can be applied with a short nap roller, brush, trowel or sprayer.  Allow NS97

to dry until tacky to touch, but non-transferable to finger. This may take as little as 10 minutes, but usually no more than 45, depending upon temperature, humidity, internal moisture level/porosity of substrate and application thickness.  

 

Tile may be set immediately after membrane is installed on horizontal surfaces.  If water test is required, allow 48 hours to cure.  

 

See the label on NS97 container or the specified membrane installation sheet for complete application instructions.  Please refer to the Primer Reference chart to ensure appropriate substrate grade for the application.

 

Moisture Vapor Transmission:

NS97 Primer will protect against Moisture Vapor Transmission (MVT) when used with NAC sheet membranes providing 10#/1000 SF/24 HRS protection.

 

Coverage:

NS97 will cover 300-400 square feet per gallon depending on applicator type and porosity of the substrate.

 

Clean Up:

Tools, equipment and spillage may be cleaned up with mineral spirits.

 

Storage:

Store in original, tightly sealed container out of sun at 60-95 degrees F. NS97 may gel if stored at lower temperatures but will return to normal viscosity at 70 degrees F.

NS97 has an 18 month shelf life so be sure to rotate stock. 

 

Packaging:

NS97 Primer is available in one gallon cans

(4/carton) and 5 gallon pails. 

 

Caution:

Avoid contact with aluminum application equipment (spray guns, pumps, canisters) copper, copper alloys or polystyrene foam.
