Flexible plastic thread, easy to install at rounded corners. In particular, advanced technology helps the decorative vein layer on the overflow not to be broken when bent. Besides, modern technology also helps this type of mold to wear a variety of designs and diverse designs.

This type of molding can be easily transported or installed because of its high strength and resistance to physical impacts. Not easily deformed or chipped on impact and extremely light weight. This product is an extremely economical choice as they are extremely cheap but also save additional installation and shipping costs.

The plastic material makes this decorative molding 100% waterproof. You don't need to worry about the rod being deformed or changing color when it encounters water.

There are quite a lot of poor quality plastic moldings floating on the market, making users skeptical about the product. It only uses impurity plastic that is brittle and has the risk of emitting toxic gases. At the same time, poor quality moldings do not guarantee the color of the pattern to remain stable during use.


Classification of hot trend plastic molding models

The hot trending plastic molding models include 3 names: ps moulding, pvc moulding and pu moulding. The features of each type of molding will be analyzed in detail below.


PS is a hard plastic molding, produced by plastic material Polystyrene. The plasticity of the mold is not high. In return, ps plastic molding has good impact resistance. In particular, the inside of the molding has an activated carbon component, so it has the ability to disinfect, filter gas, and limit odors.

PVC thread spool

PVC thread is a decorative material formed by plastic materials Polyvinyl Chloride. Because of the sturdy plastic material, the pvc formwork has the highest durability of the 3 hot trend plastic molds today. On the other hand, the weight of the formwork is also at the highest of the three types and cannot be installed at the arch or round position.

PU thread

PU molding is a flexible plastic molding, produced by Polyurethane plastic material. Because it is a flexible plastic mold, the impact resistance of this product is somewhat limited. However, they are highly sought after because of their excellent flexibility, often used in curved corners.

Applications of plastic moldings in interior decoration

The application of plastic molding is to cover the gap between two planes, for example:

  • The position of the edges of the wall and ceiling plastic panels.

When installing wall / ceiling plastic panels, it is imperative to cover the cross section. Instead of using braces, we can apply molding to make the work more perfect.

  • Location of wall corners: use corner molding, end molding.

In order for the building to have a soft and flexible beauty, the position of the corners should have the presence of a molding. Not only that, the position of the outer corner of the wall is very susceptible to damage due to impact, so the outer corner molding plays an effective protective role.

  • Position between wall and ceiling: use ceiling corner plastic molding.

It is not necessary to install new panels to use ceiling corner molding. Ceiling threading has been used for a long time because it brings good aesthetics to the interior.

  • The position between the wall and the floor: use plastic skirting boards.

When installing plastic or wooden floors, it is necessary to leave a gap for the floor to expand. At this time, the skirting board plays the role of covering that unlucky gap. The hollow plastic skirting boards are also used as places for electrical wiring.

  • We can simply use molding to decorate the wall/ceiling, no longer monotonous by molding picture frames, back only, borders, etc.

Is plastic molding simple or not?

The construction of plastic molding is very simple. First, we just need to prepare a flat and dry installation area and then determine the mounting position with a gauge. After that, we proceed to paste the mold on the wall right at the position marked with ink pen. Finally, we fill the gaps with milk silicone glue and putty.

How to stick plastic molding

To stick the plastic molding on the wall, we will inject the special glue on the back of the formwork. This glue takes a long time to dry, so it is necessary to combine double-sided tape. After gluing, we perform more nailing to the formwork to be sure. The slats have been cut to the proper length for use.

How to cut plastic molding

If the cutting operation is not standard, the connection between the beams will be clearly visible. The standard way of cutting molding without adjustment is to follow 2 rules:

  • Cut the standard plastic molding corner at a 1-degree angle to join the formwork at a right angle.
  • Cut molding at an angle of 30 degrees to extend the molding without exposing the seam.
