Instructions for installing 2-layer polymer-coated wood plastic flooring S140V23

2-layer open-groove polymer-coated wood plastic flooring (2-layer open-groove wood plastic flooring) S140V23 is a type of flooring specifically used for outdoor projects such as swimming pool floors, garden floors, terrace floors, etc. The product is made of 35% HDPE plastic + 55% wood powder + 10% additives, with a lifespan of up to 20 years with an expansion rate of 0,1%.

6 notes when installing 2-layer open-groove wood-plastic flooring S140V23:

1. The foundation has a slope of 2 - 3% to best support the drainage process under the floor.
2. Required to be constructed on concrete with thickness ≥50mm
3. Distance between bars from 200 - 350mm
4. Distance between floor bar and wall ≥15mm
5. The frame material is stainless steel bar with size ≥30x30mm, thickness ≥1,4mm
6. At the floor connection position, it is necessary to install on double ribs, the distance between 2 double ribs is 5 - 20mm and the distance between 2 floor bars right there is 3 - 10mm.
7. S140V23 floor bars are connected via specialized stainless steel pins to create gaps of 3 - 5mm.

Step 1: Prepare tools and materials for constructing 2-layer wood plastic flooring

Supplies

Below are 6 types of materials that customers need to prepare when constructing 2-layer wood plastic flooring S140V23:

1. 2-layer open-groove wood plastic flooring S140V23
2. Stainless steel bar (size ≥30x30mm, thickness ≥1,4mm)
3. Specialized stainless steel pin
4. Stainless steel screws
5. 2-layer wood-plastic V-shaped strip (V50X50)
6. Copper nail

Tool:

6 necessary tools to construct 2-layer polymer-coated open-groove wood-plastic flooring include:

1. Cutting machine, drilling machine, welding machine, nail gun
2. Drill and screw bit set.

Step 2: Surface treatment for 2-layer open-groove wood-plastic flooring

The construction surface must meet the following 3 technical requirements:

1. Stiffness: The surface must be solid and have good load-bearing capacity.
2. Flatness: Surface must be flat, not rough, not peeling, pitting, cracking or rippling.
3. Tilt: The surface should be designed with a slight slope of 2% to 3% towards drainage points to ensure that water can flow and drain quickly, without stagnating on the surface.

Compliance with these technical requirements will help protect the structure from water damage, increase the life of the structure and ensure the safe and long-term use of the structure.

Step 3: Install the frame on the construction surface

The skeleton is joined together by welding and the welds need to be smoothed and painted with anti-rust paint.

Using a welding machine, weld the ribs firmly.

Install the skeleton on the surface of the construction

Step 4: Proceed to install the first wood plastic floor

The first S140V23 wood plastic floor bar is installed on the frame bar by the following 3 steps:

1. Fix the stainless steel pin to the frame, install the first 2-layer wood plastic floor bar into the stainless steel pin at the locking groove position.

Install stainless steel pins for the first wood plastic floor bar, ensuring the alignment of the pins.

Install the first floor bar onto the frame and stainless steel pins

2. Install the specialized stainless steel pin into the remaining locking groove of the 2-layer wood plastic floor bar.

3. Drill a pilot hole and fix the stainless steel pin on the crossbar with stainless steel screws.

Kosmos recommends the frame distance and floor distance at the junction between 2 floor bars:

In case of large construction area, it is necessary to connect the wood plastic floor. Each floor bar will be on 2 different ribs. The distance between 2 ribs is 5 - 20mm.

When installing the floor bar at the double rib, it must not protrude more than 10mm from the rib, otherwise warping will occur, and in the long run it can cause serious consequences or floor breakage, the distance between the 2 floor bars at the joint point is 3 - 10mm.

Step 5: Install the remaining plastic wood floor bars until completed

4 remaining steps to install wood plastic floor panels until the floor is completed:

1. Insert the groove of the next floor bar into the stainless steel pin of the first floor bar.

2. Install the specialized stainless steel pin into the remaining locking groove of the 2-layer wood plastic floor bar.

3. Fix the stainless steel pin on the frame with stainless steel screws.

4. Repeat the above 3 steps until the project is completed.

Kosmos recommends:

• The distance between the floor bars is connected by specialized stainless steel pins from 3 - 5mm to allow the S140V23 floor to expand.

• Distance between 2 ends of floor bar when placed on double rib bar is 3 - 10mm.

Below is the seasonal expansion chart of 2-layer laminate flooring.

Note: Outdoor plastic Laminate flooring should be installed in a staggered 50 - 50 pattern (forming a ladder). That is, 2 floor bars next to each other should be installed with the wrong length in the ratio ½. This installation method helps to ensure the highest level of floor structure.

Step 6: Cover the edges of the finished 2-layer laminate flooring and it's done.

Before installing the V-shaped strip, we need to cut the wood-plastic floor bars to cover the installed frames. This helps to cover the frame, creating an even and beautiful floor surface.

1. Measure the height of the structure from the floor to the base of the frame

2. Cut the wood plastic floor panels to the measured height

3. Use screws to drill the bottom floor bar and the top floor bar or frame (if drilling the floor bar onto the frame, insert a wooden bar first as shown in the picture), but do not drill into both.

Note: At the right angle position, the floor board needs to be cut at a 45° angle.

4. Cover the floor edges with V50X50 wood plastic V-shaped strips to complete the project. Please note that at right angles, the V-shaped strips need to be cut at a 45° angle.

Customers use 1 of 2 following ways:

Option 1: Fix the V-shaped strip to the floor with glue. Then, use a drill, pilot drill and screw stainless steel screws to fix it firmly (distance between screw holes ≤35cm).

Apply Kosmos exterior glue to the strip and secure to the floor.

Secure with stainless steel screws for added security, distance between screw holes ≤ 35cm

Option 2: Fix the V-shaped strip to the floor with glue. Then, use a nail gun to nail the copper strip again for security (distance between nail holes ≤10cm).

Apply Kosmos exterior glue to the strip and secure to the floor.

Additional fixation with copper nails, distance between nail holes ≤10cm

At Kosmos Vietnam, in addition to the S2V140 open-groove 23-layer wood-plastic flooring, there is also the S2T145 seamless 22-layer wood-plastic flooring. S145T22 floor has good load-bearing capacity, simple construction, and is very easy to clean..

Note: Instructions are for reference only. To have the most suitable construction plan, it is necessary to survey the specific project and come up with an optimal construction solution.
