The best and how to properly glue glass to wood, features and choice of composition
Despite the strict requirements for such products, carpenters offer several solutions to the question of how glass can be glued to wood. However, when choosing a means of fastening these materials, it is necessary to take into account the structure and type of surfaces. For embossed glass, reinforced compounds are suitable, and for aquariums, those capable of withstanding many years of contact with water.
Basic Adhesive Requirements
Unlike other materials, glass has a low degree of adhesion. Therefore, in this case, specialized products are used for gluing, which must meet the following requirements:
- nontoxic;
- raincoat;
- very elastic;
- after drying, it remains transparent;
- thick consistency;
- resistant to extreme temperatures.
The adhesive must also be suitable for glass. That is, funds of this type should be characterized by increased adhesion.
As noted, when choosing an adhesive, it is necessary to take into account the peculiarities of the glued surfaces. The more complex the texture of the glass, the higher the adhesion should be.
Which glue is right
Despite the fact that increased requirements are imposed on the characteristics of the adhesive used for fixing glass, there are several types of such means.
Liquid Nails
Liquid nails are a versatile product that can be used with a variety of materials. This product adheres well even to uneven surfaces.
Liquid nails are classified into 2 types. The water-soluble variety does not tolerate contact with water. But this kind of liquid nails are better for bonding porous materials. For bonding glass and wood, it is recommended to purchase an organic soluble type. These liquid nails dry quickly but have a pungent smell. Therefore, you must work with this product outdoors. Liquid nails are more often used for gluing wood and glass. This is due to the fact that this composition can be applied both around the entire perimeter and pointwise. This approach reduces glue consumption.
AVP
Inexpensive glue, also used for working with different materials. PVA in contact with open fire does not ignite and does not emit an unpleasant odor. This product can be used at home. PVA tolerates temperature changes and mechanical stress well.
When buying this product, you should take into account that carpentry is used to connect wood and glass, not office glue. The latter is used when working with paper. PVA glue is recommended for joining compact pieces of glass and wood. When working with other materials, other means are appropriate.
"Thermoactivated 3M TS230"
"3M Thermosetting TS230" requires heat treatment after application (a household hair dryer will do). Thanks to this effect, the composition quickly gains strength and provides a reliable connection of materials. This product can be used to bond glass to various surfaces, including wood.
Scotch-Weld two-component adhesive
A two-component adhesive provides a strong bond between glass and wood.This composition has a low viscosity and creates a sealed layer that does not let water through. The joint remains transparent regardless of the thickness of the glue applied.
Double-sided tape
This variant of surface bonding is used in cases where the glass is opaque. In addition, double-sided tape is suitable for securing parts of the material that remain hidden from view.
Work rules
Before starting work, it is necessary to clean the surface from dirt and remnants of old glue. It is also recommended to degrease glass and wood with alcohol or other solvents. These products are also suitable for removing glue.
Glass and wood are bonded according to the following algorithm:
- Both materials are pre-treated with putty or other means that eliminate visible defects (chips, cracks, etc.).
- In places where glue is applied, glass and wood are treated with fine sandpaper. This increases the degree of grip. That is, the glue will more reliably connect the materials with each other.
- The adhesive is applied and the surfaces are pressed.
The procedure for applying the glue depends on the type of composition chosen:
- ACP. The adhesive should only be applied to one surface, avoiding the formation of bubbles. After that, the materials should be kept under load for half an hour.
- "Moment-Crystal". After applying the glue, the created connection must be dried with a hair dryer for 15 minutes. During this time, the composition only has time to dry. The tool gains strength after a day.
- "BF2" and "BF4". Both products must be dried after application.In this case, a construction hair dryer is recommended, since this glue gains strength when exposed to a temperature of 140 degrees. Then you need to connect the glass and wood and squeeze, applying maximum effort.
If liquid nails or PVA are used to connect wood and glass, the agent should be applied only to a surface with a thin layer. If this last requirement is not met, the adhesive remains visible after curing.
Two-component products are applied using a different algorithm. In this case, one surface should be treated with glue, and the other with an activator. After that, you need to firmly clamp the materials together and stand for five minutes.
