So I Bought Your PC Epoxy for a Repair– Now What??? (Hint: Surface Preparation)

By Repairs, Uncategorized

There are basically two types of people roaming the hardware stores these days – those who are naturally good at fixing things up (and even enjoy doing it), and those who just really want to save themselves some cash. Some folks are a little mixture of both. But whatever category you fall into (full disclosure not necessary), there is one gargantuan hint to any successful epoxy repair.

You must effectively prepare your surface BEFORE the application of any epoxy product for full effect and durability. No matter what your surface may be.

Why, you may ask? Because epoxy must adhere to surfaces, and surfaces are often covered with dust, dirt, grease, oil, oxide films, etc. All these contaminants, even at a microscopic level, will interfere with the strength of your finished epoxy project.

Fiberglass

  • Prep surfaces by making sure they are clean and free of dirt, oils, etc. Note: Always clean the surface before sanding. Sanding the surface with sandpaper does not remove wax or other contamination. Sanding often melts greases and oils into the surface making it impossible to obtain a clean surface.
  • Lightly sand or “rough up” the fiberglass surface. Caution: Do not sand excessively. This will create porosity in the surface that will have to be filled.
  • Blow off the surface with clean, dry, compressed air while dry wiping to remove sanding dust and residue.

Wood

  • Surfaces to be bonded must be free of dirt, oil, decay, etc. Denatured alcohol works very well to clean surfaces before applying.
  • If surfaces are previously painted, it is best to strip paint before utilizing epoxy wood repair products.
  • For best results, rough up the surface that PC-Woody® or other PC Wood Products will be bonding to with a light grit sandpaper.
  • Normally, a vice grip or a clamp is not needed for an epoxy wood repair. Prop or tape heavy objects to a wall or ceiling.

Glass

  • Surfaces to be bonded must be free of dirt, grease, etc. Denatured alcohol can be used to clean and prep the surface.
  • Dry thoroughly before beginning the epoxy repair process.
  • For best results, rough up the surface to be bonded if you can. However, when you want the result to be clear and seamless (as with the case of a broken crystal vase etc.), simply press the two clean surfaces together with PC – Clear.

Concrete

  • All concrete surfaces must be cleaned of any grease, dirt, or debris.
  • If holes are being drilled, be sure to blow out dust from the bottom of the hole/crack. Brush the hole/crack with a nylon brush. Blow out dust again.

 

 

Taking the time to complete a thorough surface preparation is going to make all the difference in the quality of your project, and help to provide a lasting result for your DIY fix-it efforts. And of course, if you have any questions at all, feel free to ask our experts or visit our PC – Products page on Facebook!

Extreme Weather Wreaking Havoc on Your Concrete or Blacktop? No Sweat (or Chills!)

By PC Xtreme, Uncategorized

Make no mistake about it – no matter where you live, the weather can be quite variable – and even downright cruel. The repeated freezing and thawing of concrete or blacktop over the course of time is quite likely to cause cracking, no matter how well the surface has been poured and treated. Heavy use, high traffic, and/or the movement of industrial equipment across surfaces will require the use of something super-human for repair purposes.

Extreme Times Call for Xtreme Measures

Is There Really Such A Thing?

Impossible, you say? Try us. We encourage you to challenge us with unusual applications, extreme environments, and difficult repairs. PC Xtreme is self-leveling polyurea epoxy, and will neatly fill both cracks and joints no matter what the temperature may be.
