Table with a stylish worktop made of epoxy and plank


An interesting countertop was made by the Master. Choosing the right color scheme, the master made a stylish table that fits perfectly into any environment.

To make a table, the master needed the following

Tools and materials:
-Boards;
Epoxy resin;
-Yellow pigment;
-Rail;
-Capacity;
-Scotch;
-Grinder;
-Burner;
-Foots for the table;
- Paint brush;
-Libra;
-Remedies;
-Fasteners;
-Screwdriver;
- Water-based dye;
-Drill;
-Rule;
- Crosses for tiles 8 mm;
-Acrylic sheet;
-Double sided tape.


Step One: Material Preparation
The master bought a board in a building goods store. It is important that the board is even and dry. The place of work must be dry without dust with an air temperature of at least 20 degrees. Epoxy must also have a temperature of at least 20 degrees. In order to achieve the desired effect, the countertop will be poured into four approaches.


Step Two: Boards
He puts the boards on the desktop in random order. The gap between the boards makes 8 mm. The gap between the boards and the frame is 12 mm. For contrast, some boards are coated with a water-based dye, others are slightly burned with a burner. Measures the size of the future countertops on laid out boards. Sticks a sticker on each board and removes it from the table.






Step Three: Prepare the fill spot
Double-sided tape glues on a flat desktop. On a sticky tape sticks a sheet of acrylic. Around acrylic makes a side of the plank. The choice of acrylic is due to its poor adhesion, and epoxy will not stick to it. Acrylic can be used several times.











Step Four: Epoxy Preparation
For his countertops, the master uses the proprietary GlassCast® 3 resin. Mix it with 2 parts of the resin with 1 part of the hardener. But first, the master makes the calculation of the required quantity. With a table area of ​​1.28 sq.m. about 13 kg of resin will be required. Next master on electronic the balance weighs the right amount of resin and adds color. Through an experiment, the master calculated that one kilogram of resin required 3.5 grams of pigment. In this case, the color is saturated and does not lose transparency. A total of 13 kg produces 45 grams of dye. The master adds dye to the resin (the resin has not yet been mixed with the hardener) and mixes thoroughly.





Step Five: First Layer
The first layer is 3 mm. Calculates the right amount of resin and hardener.In this case, it will be 2, 56 resin + 1, 28 hardener = 3.84 of the finished solution. The master kneads the resin for 3 minutes, then pours it into another container and kneads another 3 minutes. After mixing, pour out the resin and level. If necessary, warms up with a burner (this will help remove air bubbles).
After about 12 hours, the resin will acquire stage "B", in which by pressing on the resin it is slightly pressed, but does not stick to the glove. It is at this moment that you need to fill the second layer.







Step Six: Second Layer
The second layer is 1.5 mm. Knead the right amount of resin. Pours part of it onto the previous layer. Spreads the bottom of the boards with resin and puts it on the table. It must be laid so that there are no air pockets under the boards. Lubricates the boards with resin on all remaining sides. Using crosses, aligns the gaps of 8 and 12 mm. Leaves for a few hours. Then it removes the crosses, and leaves the resin to solidify to stage “B”.











Step seven: layer three
This resin will take the most resin. It will be necessary to fill in the resin between the boards and a little above the boards. Everything, as in the previous steps: calculation, mixing, filling. After pouring, the burner necessarily expels air bubbles. Well, it leaves to stage "B".






Step Eight: Fourth Layer
The fourth layer is the last and is 3 mm. When pouring, it is especially necessary to shed corners and adjacent surfaces. After pouring, the countertop should dry for at least a day, and ideally several. During drying, the master closes it with a lid. On a completely hardened resin, when you press the surface with a nail, no trace remains.


Step Nine: Grinding
Deletes a side. Turns the countertop over and removes the acrylic sheet. Then polishes the end parts of the countertop. For sanding it uses sandpaper from 240 to 1200 with water. After polishing, it polishes the end parts.













Step Ten: Installing the Feet
Marks the location of the legs. Drill mounting holes. Screws the table legs.




All is ready.


It’s not a sin to wash the successful completion of work.

With this question you are on a technical and scientific site, and here is popular. Well, or you can take a piece of acrylic to the laboratory, pay the money and they will tell you everything about its parameters, if it is so important to you and somehow it will affect the table made of epoxy resin that you have made.
"poor adhesion"?
And how much will it be in MPa? smile

Is this contrary to the phrase "poor adhesion"?
Poor adhesion to metals and other materials

adhesion - adhesion strength The combination of forces that bind a coating to a painted surface. [GOST R 52804 2007] adhesion A surface phenomenon leading to adhesion between heterogeneous materials brought into contact by the action of a physical ... ... Technical Translator's Guide
ADHESION, the attraction of the molecules of one substance to the molecules of another. In rubbers, adhesives and pastes, the property of adhesion to hold various substances together. see also COGESION. Scientific and technical encyclopedic dictionary.
For the assessment of adhesion / cohesion, criteria have been adopted and approved [2].
Bonding intensity is measured in MPa (megapascals).This number indicates the effort that will have to be applied to separate the coating from the base. For example, if the label says that the product provides adhesion of 1 MPa, then in order to tear it off, you will have to apply a force of 1 N per mm2 (about 100 g / mm2).

Poor adhesion to metals and other materials, low surface hardness, a tendency to irreversible deformations under load, high temperature coefficient of linear expansion of ar, low thermal conductivity are often the cause of increased instability of the geometric parameters of products made of polymers, the occurrence of internal stresses in their volume, which can subsequently lead to cracking. [1]

Poor adhesion films are obtained by applying low quality paints and grease stains on the surface to be coated. [2]
