When in a DIY store, I am confused by the amount of products available. Why should I choose your product?

We do realize there can be lots of confusion when choosing the right product for the job. We pride ourselves on having products that perform as advertised and after 60+ years this assumption has proven itself out. Knowing there are many types of products, you need to determine how critical your repair is before you choose any product. If you need a permanent repair you need a permanent type repair product. We thrive on providing products to people who have tried other products that did not perform. If you want it done correctly, always look for the “PC” on the label.

Can I fix..?

Which of your products can I use to repair vinyl?

None of them will be reliable, and none of the other epoxies on the market will be either. Vinyl is not a good candidate for repairing.


Which product is the best for granite counter tops?

Depending on the colour you want; either PC-7® (dark grey) or PC-11 (off white) will work great and are recommended by many of the manufacturers of these countertops. For invisible seams, we recommend PC-Clear™.


Will your products bond to stainless steel?

Yes they will. Stainless steel has an oily film that needs to be cleaned with denatured alcohol. Rough up the area to be repaired with sand paper and you are ready to fix away.


Will any of your products bond to plastic?

Plastic repair is very difficult and in many cases impossible. Most epoxies have limited success on plastic surfaces. In general, if it is a soft and flexible plastic, you will not have any luck with any product. If it is a rigid plastic like fibreglass, ABS type plastics etc. you can use our products. You need to sand the shiny surface from this plastic first and then clean the area well before applying. PC-SuperEpoxy® has a pretty good track record on this type of repair. If on fibreglass, we recommend PC-11® as well.


Do your products bond to rubber?

They do.


The bottom of my garage door is rotting out. How do I fix this?

We would suggest the following: Clean the rotted area of any loose dirt and dust. Apply PC-Rot Terminator® product to the area with a brush. Repeat if needed. After fully cured, you can use PC-Woody® to rebuild the area. Let this cure, then sand and prime and paint. Take lots of photos of your completed project; you will be the envy of all you show them to.


Will your products bond to polypropylene, polyethylene and polystyrene?

Our products will bond to polyurethane. As for the rest of the polys., no. If unsure what you are dealing with, it is best to test a small area first.


I need to bond Styrofoam and the product I used melted it? Do your products melt Styrofoam?

NO. Our products do not build up extreme heat during the curing process and do not contain solvents that might react with Styrofoam.


Our picnic table is rotting. What do you make that will repair this?

Ah, the joys of dining al fresco! Since this, to us, would be considered more along the line of being structural (you dont want to end up on your butt with chili sauce all over you), we would suggest using PC-Rot Terminator® wood hardener to harden the deteriorating areas, and then rebuilding any missing parts with PC-Woody®. Fire up the grill!


I have a hole on the inside of my dishwasher. What can I use to fix it?

We can’t relate to this. We are cheap and wash them by hand. You should use PC-11®. Once it cures, it is non-toxic and nothing will leech into the water. It will also hold up very well to the hot water and vibration.


My wife broke a porcelain statue. How can I fix it?

Yeah right, your wife broke it. If it is a clean break and no missing pieces, you can use PC-Clear™. If some of the pieces have shattered and the area needs to be rebuilt, PC-11® is an excellent choice.


Which product should I use to repair my aluminum boat?

Most products have a tough time with aluminum, but you’re in luck. You can either use PC-7® or PC-11® for this type of repair. Make sure the area is well cleaned and rough up with sandpaper first. Aluminium oxidises and forms a powdery film on the surface. Cleaning and roughing up the area will eliminate this prior to making the repair.


I have water seeping into my basement through a crack in the wall. What do I do?

You can do one of two things. First, you can just fill the basement with water and make it into an indoor swimming pool. This is popular with friends and relatives. The other option is to seal the crack and stop the leak. We would recommend PC-7® for this application. Clean out the crack and make sure it is dry first. If you cannot dry the area, use PC-11®.


I need to splice two electrical wires together. The wire nuts keep vibrating loose. This is on a trailer. Do you have something that will work?

We would suggest PC-Metal™ putty epoxy. The bond will be good and it will take the vibration well. This is also non-conductive. This also works well for underground wire splicing.


How do I patch my wooden siding? Wood fillers do not work.

PC-Woody® will work for this and will not shrink. PC-Woody® will also hold up to expansion and contraction due to temperature changes and can be painted. This exact application was highlighted on a recent “Today” show in the USA and our PC-Woody® was one of the recommended products.


I have a hole in my petrol tank. Will any of your products fix it?

The tank can be fixed by using PC-Metal™ putty epoxy, or PC-7® paste epoxy. The PC-7® will be more durable, but will take longer to cure for service. It depends on how much of a hurry you are in. Either product will hold up to petrol or fuel oil once they have cured.


What can I use to repair my surf board?

Use PC-11®. It is a great choice for repairs to fibreglass. Gnarly, dude!

Using PC

How to I prepare for the repair?

Each product category has a notation on preparing for the repair. Making sure the area to be repaired or bonded is prepared correctly is 80% of the battle. The products all work best on dry surfaces, but many can be used in a wet or underwater environment. The most important factor to keep in mind is that the surface being repaired or bonded to must be as clean as possible. The adhesives are only as strong as what they are bonding to, so the cleaner the better.


Do I have to remove the paint before using your products?

Only if you want it to last for a long time. Sand as much of the paint or rust or other materials from the repair site first. Preparation is 90% of the job. Adhesives are only as strong as what they are bonding to. If there is paint etc. then, the epoxy is only as strong as the paint.


How do I clean up after using PC?

As with the surface prep, each category has clean-up tips for the products. Some of the products we offer clean up with soap and water while others require a solvent or alcohol for proper clean-up. Please check the specific product page for more in-depth details.


The product is not curing. What went wrong?

There can be several reasons for this. 1. The product may not have been thoroughly mixed. 2. It may be below the curing temperature and needs to be warmed to finish curing. The products are pretty simple and easy to use, and this just about covers the curing issue.


The bond let loose after it was cured. Why?

The most common problem with this is that possibly the surface being bonded to was not clean. Also, certain plastics are not compatible with our products or others for that matter. Please see the troubleshooting section for more details.


Are there any toxicity issues with your products?

As with any product on the market, there can be skin irritation caused by the uncured products, but as a general rule there are no issues with cured products.
