Technical Data Sheet
General Preparation:
The temperature of the product, the surfaces, and the working area should be between 41°F (5°C) and 104°F (4°C). For best performance, store
cartridge at room temperature at least 24 hours before use. Cut plastic nub on top of cartridge (be careful not to cut into the threads) then screw
on plastic nozzle. Insert cartridge into caulking gun, cut nozzle at a 45° angle to desired bead size (3/8” is recommended for optimal joint protection).
Joint Preparation:
The number of joints and the joint width should be designed for a maximum of ± 25% joint movement from the initial joint width. The depth of the
sealant joint should be ½ the width of the joint. The maximum depth should not exceed ½ inch (13 mm) and the minimum is ¼” (6 mm). The
maximum recommended joint width is 1-3/8 inches (35 mm). See chart below.

To maintain the recommended sealant depth, install backer-rod by compressing and rolling it into the joint channel without stretching it lengthwise.
Closed-Cell Backer-Rod should be approximately 1/8” (3 mm) larger in diameter than the width of the joint to allow for compression. Soft Backer-
Rod should be approximately 25% larger in diameter than the joint width. Backer-rod becomes an integral part of the joint. The sealant does not
adhere to it, and no separate bond breaker is required. Do not prime or puncture the backer-rod.
Application:
Using a caulking gun, apply sealant with steady pressure, forcing sealant into joint. If the depth of the joint exceeds 1/4” the use
of a backer rod is recommended. Perfect Finish House and Home Premium Sealant will not pop or splatter and will dispense smoothly on extrusion
from the cartridge. Tooling of the sealant is allowed. Full cure may take 24-48 hours or longer depending on ambient conditions and
volume of sealant used and porosity of the substrates. Sealant is paintable in 30 minutes with a latex paint. If using oil based/alkyd paint, a latex
primer should be used first.
Clean-up:
Clean tools and any uncured sealant residue immediately with mineral spirits or paint thinner. Cured sealant must be carefully cut away with a
sharp-edged tool.
NOT DAMAGED BY FREEZING. Store in unopened containers in a cool, dry area away from heat and direct sunshine under standard
conditions. Standard storage conditions are defined as 72 ± 4ºF (22 ± 2ºC) and <50% relative humidity. Elevated temperatures will reduce shelf
life. In cool or cold weather, store container at room temperature for at least 24 hours before using. Use an approved hazardous waste facility
for disposal facility. Hardened material may be disposed of in the trash.
LABEL PRECAUTIONS
WARNING! UNCURED SEALANT IRRITATES EYES, SKIN AND RESPIRATORY TRACT.
WARNING! Contains silane and crystalline silica. May be harmful if inhaled or swallowed. Methanol is released during
application and cure, which may affect the nervous system causing dizziness, headache, or nausea. Use in a well-
ventilated area. Do not breathe vapors. Avoid eye and skin contact. Prolonged or repeated skin contact with uncured
sealant may cause irritation. Wear gloves and safety glasses when applying product. Remove contact lenses before
using sealant. Wash hands after using.
FIRST AID: For eye contact flush with water for 15 minutes. Call a physician if irritation develops and persists. For skin
contact, wash thoroughly with soap and water. If affected by inhalation, remove to fresh air and get medical attention. If
