Title: Use of Seaming Adhesives in Cold or Hot Substrates
Content Description: Seaming Adhesives, in particular, Methyl Methacrylate Adhesives, which are commonly are used in seaming counter tops, such as solid surface, quartz, marble, granite, porcelain or sintered materials are designed to work in controlled environments.  The reaction of the resin with the hardener (generally a peroxide, and in Methyl Methacrylate Adhesives), is benzoyl peroxide, creates an exotherm (that means heat generating) reaction.  The effect of the exothermic reaction is that energy is given off, generally in the form of heat.  So, often, if there are large masses of the adhesive, you might experience a boiling, or popping of the adhesive, as the exothermic (heat) is great enough to cause certain components, like a monomer to boil.  This is often found in warmer conditions, or on warm summer days, where there may be an excess of material over seams, or expunged in a trash can to purge the adhesive.  It is that heat that creates a good bond of the adhesive to the substrates.  Too much heat, and one often experiences boiling, or the yellowing of the seam.  It is also the heat that contributes to the strength of the adhesive.  Certainly, if bubbling occurs, one might even experience a weaker joint due solely to the high temperature achieved by the adhesive at or near the joint. Therefore, we recommend in high temperatures, such as those greater than 85F, that seaming adhesive is applied not in large masses, but in smaller masses that do not generate much heat.  Seaming above 85F can cause some of the less pigmented products to produce a slight yellowing effect.  It is important to note that often it is the substrate temperature that is most important.  Hotter substrates, such as darker colors, seamed together in the sun, may cause more of this issue, so we don’t recommend seaming about 85F.  Should you find that the substrates are hotter than 85F, we recommend that you mist water on the substrate to cool the seaming area down.  In general, it may take 30 to 45 minutes of spray water to reduce the temperature below 85F.

Cabinet Sanding 101 the Do’s and the Don’ts

 

Cabinet Sanding 101 the Do’s and the Don’ts

 

dimg1

Whether you’re crafting custom cabinetry, refinishing doors, or preparing surfaces for paint and stain, choosing the right abrasives and sanding approach makes all the difference in your finish quality and workflow efficiency.

Why Does Sanding Matter in Woodworking? 

Proper sanding is more than just smoothing wood; it’s about preparing a surface that will accept finishes evenly, look professional, and stand the test of time. Whether you’re removing old finishes or refining raw wood before staining, the materials and techniques you choose shape the end result. 


What are Top Abrasive Options for Sanding Cabinet Doors? 

Foam Abrasive Sponges - The Game Changer

Innovations like foam abrasive sponges (such as EKASILK PLUS) have transformed sanding by blending the flexibility of hand sanding with the efficiency of machine sanding:

  • Long-lasting and washable
  • Flexible enough for edges, contours, and recessed profiles
  • Available in multiple grit stages for a complete sanding progression

These sponges make fast work of flat panels and intricate profiles alike, dramatically reducing sanding time while improving finish quality. 

Sanding Discs & Backing Pads

For machine-assisted sanding, especially on larger surfaces, quality sanding discs are essential. Look for:

  • Paper-backed discs for general wood sanding
  • Cloth-backed discs for heavier stock removal
  • Film-backed abrasive sheets for fine finishing

Coupled with the right backing pad, discs help you achieve consistent, professional results without hand fatigue.

Matching Abrasives to Your Cabinet Type

Every door style has its own challenges:

  • Flat panel doors need broader, consistent sanding surfaces
  • Shaker or profiled doors demand flexible abrasives that follow contours
  • MDF doors produce more dust and may require different grit choices than natural wood

Choosing the right abrasive for each style not only saves time but also protects your workpiece from scratches or swirl marks.

What Are Different Sandpaper & Grits Used For? 

A Quick Guide: 

Fine finishing requires the right grit sequence. A typical progression looks like:

  1. Coarse (40-80 grit) – removes old finishes and levels surfaces
  2. Medium (100-150 grit) – smooths initial scratches
  3. Fine to Very Fine (180-220+ grit) – prepares surface for stain/paint
  4. Extra-Fine (320+ grit) – ideal between coats for a glass-like finish

Starting with the right grit and progressing thoughtfully ensures a smooth surface that accepts stains and paints beautifully.

How to Match Sanders & Tools to the Job? 

Selecting the right sander can also improve your workflow:

  • Orbital Sanders – versatile and beginner-friendly for general surface work.

  • Disc Sanders (3×4 or 5-inch) – excellent for cabinet doors and flat panels.

  • Belt Sanders – aggressive stock removal for prepping rough surfaces.

Pair quality abrasives with appropriate tools to maximize efficiency and finish quality.

 

The 3 Most Common Sanding Mistakes (and How to Avoid Them)

Even experienced woodworkers can run into sanding issues that affect the final finish. The good news? These mistakes are easy to prevent once you know what to look for.

Here are the three most common sanding mistakes we see — and how to avoid them on your next cabinet or woodworking project:

1. Tipping the Sander While It’s Running

Tilting or lifting the sander during operation can create gouges, divots, and uneven surfaces that are difficult and time-consuming to fix. Always keep the sander flat against the surface and start or stop it while it’s fully supported.

Pro tip: Let the sander come to a complete stop before lifting it off the workpiece.

2. Applying Too Much Pressure

Pushing down on the sander might feel like it speeds things up, but it often does the opposite. Too much pressure can cause:

  • Burn marks
  • Uneven material removal
  • Faster wear on sandpaper and pads

Quality abrasives are designed to cut efficiently on their own; excessive force just reduces their lifespan and your finish quality.

3. Oversanding the Surface

More sanding isn’t always better. Oversanding can remove too much material, leading to waves, dips, or sanding through thin veneers, especially on cabinet doors and MDF panels.

Stick to a proper grit progression and stop once the surface is smooth and consistent.

What is the Golden Rule of Sanding? 

Let the sander do the work.
Use light, even pressure, maintain control, and allow your abrasives to perform as designed. This approach delivers cleaner finishes, longer abrasive life, and professional-grade results every time.
