Pecora 895 NST Sausage: Silicone 20oz

Pecora 895 sausage is a high-performing, neutral curing, medium modulus silicone sealant specifically designed for structural and non-structural glazing, with excellent aesthetic characteristics in that it will not stain sensitive porous natural stones such as granite or marble and will not contribute to residue run down on non-porous surfaces such as metal or glass curtain wall facades.
Reduction in long term dirt pick up on sealant surface is also a feature of the Pecora NST line of silicone architectural grade sealants. With a dynamic movement capability of ±50% to complement its structural strength, Pecora 895NST is equally efficient as a weatherseal in the vast majority of sealant applications other than glazing.

Surface Preparation:

No sealant will maintain long-term adhesion to any substrate if the surface is not prepared and cleaned properly before the sealant is applied. Thoroughly clean all joints and glazing areas by removing all 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 by a solvent procedure or by mechanical means. Soap or detergent and water cleaning treatments are not recommended. Cleaning of all surfaces should be done just prior to the sealant application. Areas adjacent to joints should be masked to assure neat sealant line. Do not allow tape to touch clean surfaces to which sealant is to adhere.


Pecora 895 sausage does not require priming on most common substrates. Unusual building materials, special coatings and treatments of surfaces may impair optimum adhesion. Where primer is indicated, P-150 primer should be used on porous substrates and P-120 on metal. All precast substrates require priming with P-225 primer.


Install back-up fillers, setting blocks, spacer shims and tapes as specified. Apply Pecora 895 sausage in one continuous operation. Tool sealant at once after application before skin forms. Tool concave with a firm continuous stroke to assure complete sealant contact with the substrate and present a neat appearance. Remove masking tape.

Clean Up:

Immediately remove all excess sealant and smears adjacent to joints with
mineral spirits. Also use mineral spirits for removing uncured sealant from equipment. Remove cured sealant by scraping, sandpapering, etc. (Caution: mineral spirits is flammable and toxic. Observe manufacturer’s precautions.)
