Renders and Adhesives
Adhesives are designed to fix insulation external walls of the buildings, primers are used for prepare the surfaces, renders to be applied over the surfaces for finishing.
An adhesive is a gluing substance that is applied to one or both surfaces of two separate items that binds them together and resists separation. The adhesives used on external walls to fix external insulation must withstand extreme conditions. There are specialised adhesive products for fixing polystyrene, mineral wool or phenolic or wood products. They are supplied ready mixed, and have to be mixed with water at site. The wet adhesive would gain strength when drying and hold the insulation in place.
Types of Adhesives
- Adhesives for flooring,
- Adhesives for internal walls,
- Adhesives for external walls.
Flooring adhesive is any type of strong, permanent glue for adhering flooring materials to a floor or underlayment. There are specialised different types of adhesive for different types of flooring (wood, tile, rubber, cork etc), although some multi-purpose adhesives can be used effectively with multiple materials. Certain adhesives will bond better to different types of substrates. Some adhesives can be used to install flooring over plywood, and some other are for hardwood. There are specific adhesives where underfloor heating is being installed.
There are adhesives for internal walls for different materials, such as for wallpaper, for specialised wallpaper, for bonding plasterboard to substrates, for bonding tiles to walls etc, and multi-purpose internal wall adhesives.
Adhesives for external walls are created specially for polystyrene sheets, for mineral wool slabs and for both of them, and also those that can work well in winter time. There are also multi-purpose external wall adhesives.
