Troubleshooting Pin Holes Above and Below Edging Strips399

Introduction

Pin holes are a common problem that can occur during the application of edging strips to furniture. These holes can be unsightly and can also weaken the bond between the edging strip and the substrate. There are a number of factors that can contribute to the formation of pin holes, including:
Improper application technique
Insufficient vacuum pressure
Inadequate adhesive strength
Air bubbles trapped in the adhesive

In this article, we will discuss the causes of pin holes and provide tips on how to prevent them from occurring.

Causes of Pin Holes

As mentioned above, there are a number of factors that can contribute to the formation of pin holes. The most common cause is improper application technique. If the edging strip is not applied evenly or if it is not pressed down firmly enough, air bubbles can become trapped in the adhesive. These air bubbles can then expand and create pin holes.

Insufficient vacuum pressure can also lead to pin holes. The vacuum pressure helps to draw the adhesive into the pores of the substrate. If the vacuum pressure is too low, the adhesive will not be drawn into the pores properly and air bubbles can become trapped.

Inadequate adhesive strength can also contribute to pin holes. The adhesive strength should be sufficient to hold the edging strip in place and to prevent air bubbles from forming. If the adhesive strength is too weak, the edging strip may not adhere properly and air bubbles can become trapped.

Finally, air bubbles trapped in the adhesive can also cause pin holes. These air bubbles can be caused by a number of factors, including:

Insufficient mixing of the adhesive
The presence of moisture in the adhesive
The presence of dust or debris in the adhesive

Preventing Pin Holes

There are a number of things that can be done to prevent pin holes from occurring. First, it is important to use the proper application technique. The edging strip should be applied evenly and it should be pressed down firmly. It is also important to use a vacuum press to help draw the adhesive into the pores of the substrate.

Second, it is important to use an adhesive with sufficient strength. The adhesive should be able to hold the edging strip in place and to prevent air bubbles from forming. It is also important to mix the adhesive properly and to make sure that it is free of moisture and debris.

Finally, it is important to clean the substrate before applying the edging strip. This will help to prevent the formation of air bubbles.

Conclusion

Pin holes are a common problem that can occur during the application of edging strips to furniture. However, by following the tips provided in this article, you can prevent pin holes from occurring and ensure that your furniture looks its best.
