This video is to bring you a closer look at the Pemko PK33W White PemkoPrene™ Adhesive-Backed Fire/Smoke Gasketing.
Available in different lengths/sets (17ft, 18ft, 20ft, 21ft, 25ft).
For example a 17ft roll would be perfect for a 3070 door (7ft + 7ft+ 3ft = 17ft).
You can also get this in a roll of 510ft, if you have a project that needs a lot of gasketing.
This material is very supple, it is small and thin, but it gives you the impression that this is of very high quality.
The PK33 is specifically intended for very tight margins on doors and frames.
It compresses down to about a 1/16″ and it is 3/16″ when it is uncompressed in terms of the thickness.
The width of the backer is 3/8″.
It has a peel away two-sided tape that you pull off.
It is a tear-drop shape, white in color.
It has small grooves in the material.
This will be used for fire rated frames or smoke controlled openings, they are going to require some sort of material like this.
There is a link below the video to the cut sheet that shows the steps of installation.
The instructions also come on the back of the packaging.
This material will be placed on the two jams and the head.
You want to install this in pieces, not a continuous run.
If you run it continuously the inside corners will be a point of failure.
Cut and even miter your two inside corners.
The material must be installed onto very clean frames, make sure that if the frame has been painted it has fully cured.
Step one says to pre-cut.
The next step says to remove approximately 24″ of backing of the adhesive.
Personally I have found that that amount of length is too much to work with.
If you do it too fast you’re going to have a wavy look to it.
I recommend working with 10″ so it looks nice and straight.
It is noticeable if it is not straight as soon as you open your door.
Also, if you have too much hanging you do not want to unintentionally touch the frame and have to pull it off, that will fatigue the adhesive.
Step three says not to pull or stretch it to put it on, otherwise it will fail at those points as well.
Apply firm pressure along the surface once installed to make sure the adhesive is properly applied to the frame.
Just pad it down, do not run your hand along the material (that will stretch it out).
You will receive a decal to go onto the frame, showing that the opening is in compliance with the proper code for smoke and draft control.
Also, they will give you a frame cleaner as well (before applying the adhesive).
Pemko is a full-line manufacturer of all things weatherstripping related.
The PemkoPrene is their signature material, it fees very durable (feels like it wouldn’t tear as easy as silicone).
This material works well in situations where you have a shop to a showroom setting, it works well at keeping the dust and or debris from getting into the showroom.

Today we answer a few of these questions as we take a trip down to our local Farmer’s Market and learn about hydroponics and other great info from two local farmers.
