Pemko PK33D18 – Frequently Asked Questions

1) What is the Pemko PK33 adhesive perimeter gasketing used for?
The PK33 provides weathersealing around door perimeters. It seals gaps between door frames and door slabs. Creates barrier against air infiltration, dust, and moisture.
2) Which door types are compatible with the PK33 gasket?
Works on most standard commercial and residential doors. Compatible with wood, metal, and fiberglass door frames. Verify frame surface is clean and smooth for proper adhesion.
3) How is the PK33 gasket installed?
Remove backing from adhesive strip. Position gasket along frame perimeter. Press firmly for full contact. Allow 24 hours cure time before door operation. Clean frame surface before installation.
4) What compression range does the PK33 provide?
Gasket compresses to seal typical door frame gaps. Accommodates minor irregularities in frame alignment. Check manufacturer specifications for exact compression measurements.
5) Can the PK33 be used on fire-rated door assemblies?
Verify local fire code requirements before installation. Some jurisdictions restrict gasket materials on rated assemblies. Consult authority having jurisdiction for specific applications.
6) What surface preparation is required for adhesive application?
Clean frame surface with degreasing agent. Remove paint chips, dirt, and debris. Surface must be dry before gasket installation. Poor preparation reduces adhesive bond strength.
7) How do you measure for the correct gasket length?
Measure door frame perimeter including head and both jambs. Add 6 inches for splicing and waste. Order continuous lengths when possible to minimize joints.
8) What temperature range is suitable for PK33 installation?
Install at moderate temperatures for best adhesive performance. Avoid installation in extreme heat or cold. Allow gasket to reach room temperature before installation.
9) How is the gasket maintained after installation?
Inspect gasket periodically for wear or damage. Clean with mild soap solution. Replace sections that lose compression or show cracking. Avoid petroleum-based cleaners.
10) Are there related Pemko gasket products available?
Pemko offers various perimeter gasketing solutions. Browse our Pemko products for alternative profiles and mounting methods. Different gasket designs suit specific applications.
11) Can the PK33 gasket be removed and reinstalled?

12) What tools are needed for PK33 installation?
Basic hand tools include utility knife, measuring tape, and cleaning supplies. Degreasing agent and clean rags for surface preparation. No specialized installation equipment required.

    Posted by Timothy on Sep 4th 2023

    The Pemko PK33 Adhesive Perimeter Gasketing is a lifesaver for drafty doors. It's a breeze to install, and the adhesive sticks like a champ. But keep in mind, it might not fit super snug on every door, so measure twice! Overall, it's a winner for keeping my home cozy.
