$11.50
- Peocra 864 NST is a one component, non-staining, neutral curing silicone sealant. 10 oz tube
- Sealing horizontal decks, patios, driveway or terrace joints where abrasion or physical abuse is encountered.
- Sealing submerged joints or below the waterline in marine applications.
- In totally confined or air- free spaces.
- In designs that will be painted after application of the sealant. (Sealant should be applied after painting is completed).
Pecora 864 Tube NST is one-part, low-modulus, neutral-curing, high-performance silicone sealant that cures via atmospheric moisture to form a durable, flexible building seal. Pecora 864 Tube NST will not stain natural stone such as marble and granite. Because of its low modulus, high extension/compression and recovery properties, and its strong adhesion to most building materials, Pecora 864 NST performs exceptionally well under dynamic conditions accommodating long-term movement of 50% in properly designed joints.

Surface Preparation: Clean all joints and glazing areas by removal of foreign matter and contaminants such as oil, dust, grease, frost, water, surface dirt, old sealants or glazing compounds and any protective coating.
Porous substrates and precast concrete
panels using form release agents other than polyethylene film should be cleaned by grinding, saw cutting, blast cleaning (water or sand), mechanical abrading or a combination of these methods which will provide a sound, clean and dry surface for
sealant application. Dust, loose particles, etc. should be blown out of joints with oil-free compressed air or vacuum cleaned. Metal, glass and plastic surfaces should be cleaned by solvent procedure or by mechanical means. Soap or detergent and water cleaning treatments are not recommended. Cleaning of all surfaces should be done on the same day on which the sealant is applied.
Priming: Pecora 864NST does not require priming on most common sub- strates. However, we strongly suggest adhesion pretesting, either in the field or in our laboratory, on all porous substrates, particularly brick, as well as unusual building materials and other substrates where special coatings or surface treatments may impair optimum adhesion.
Where primer is indicated, P-150 should be used on porous substrates and
P-120 on special metal and plastic surfaces. All precast substrates require priming with P-225 primer.
Also, Pecora offers complimentary adhesion and stain testing in its laboratory on actual field samples of substrate from the jobsite or on representative samples from the same lots. Contact Technical Services for details.
