Types of antifreeze adhesives for granite for outdoor use, rules of use
Facing the facades, marble plinths, granite makes the architecture more expressive. Natural stone is very durable and extends the life of brick and concrete walls. The coating is influenced by solar radiation, rain, snow, wind, temperature differences. For outdoor use, a frost resistant granite adhesive is required. Inside, especially in swimming pools, artificial reservoirs, the glue must be waterproof.
Basic Adhesive Requirements
Marble and granite give exterior and interior cladding a noble and expensive look. Its service life depends on the glue with which the stones are connected to the surface of facades and flooring.
Versatility
The adhesive composition should be equally effective when performing external and internal work, resistant to temperature extremes.
Strength
The glue should be inert to alkalis, acids and ultraviolet light.
Sustainability
The density of the adhesive should not change for a long time, so that compression and cracking do not occur.
Solidification rate
The faster the marble or granite slabs are glued, the higher the quality of work.
Which glue is right
The choice of glue depends on the characteristics specified by the manufacturer and the price.
cement based
The adhesive composition includes cement grades M400, M500, M600. Inexpensive funds are used for interior and exterior work. Frost resistance depends on additives.
Polyurethane
Synthetic adhesive based on polyester. Produced in the form of putty. Curing speed depends on air temperature. The composition does not interact with aggressive media.
Properties deteriorate with prolonged high humidity.
Polyester
Two-component composition for bonding marble, available in three consistencies:
- fluid;
- viscous;
- solid.
The multi-color range allows you to use it to decorate mosaic panels.
Epoxy
The two-component composition has good adhesion properties on concrete, metal, stone, withstands low temperatures. It is used for exterior and interior cladding of structural elements of buildings.
Impregnating
Adhesives of this type are produced in the form of a gel that penetrates into the pores of the stone, the cracks. After hardening, it acquires monolithic properties with a stone, amenable to grinding, polishing. The tool is used for outdoor work due to its resistance to low temperatures and atmospheric influences.

How to choose the right one
A high quality coating can be achieved provided the correct brand of glue is selected. This will determine the strength of adhesion of the stone to the base, which means the durability of the work done. Each option requires its own brand of glue, which must correspond to the type of facing and the type of stone. Stone tiles have different thicknesses and sizes.
Adhesives have different working times after preparation. The optimal retention period for adhesive properties is 3 hours. This allows tiles to be laid with good performance.
For facade works, the glue must have:
- a vertical retention indicator of 70-80 kilograms;
- frost and frost resistance to frost at least 35 times;
- waterproof qualities;
- resist low/high temperature cooling/heating;
- color matching.
The marble slabs are glued with colorless glue.
How to paste
The choice of brand depends on the location and type of stone tile to be bonded, as well as its condition.
From granite to granite
For carrying out work indoors, polyester glue is used, which can be used up to a temperature of 0 degrees. When choosing a composition, one should take into account its consistency:
- For a solid connection of horizontal plates, a liquid form is used.
- The semi-thick composition fills the pores of the stone, restoring its strength. Once hardened, it lends itself to grinding and polishing, creating a monolithic bond.
- The walls are covered with a thick glue which, due to its high viscosity, does not slip vertically holding the tiles.
When working with polyester compounds, add the hardeners specified in the instructions. In order for the junction to be inconspicuous, a transparent or a glue suitable for the shade is selected.
Marble tiles
For finishing marble, polyester and epoxy glue are used. Polyester glue can be liquid, semi-liquid and thick. It is used indoors. Add a hardener putty before use. Epoxy is used for interior and exterior wall cladding.
Granite tiles
Epoxy glue has a high degree of adhesion to the material, which makes it possible to glue granite not only on granite, but also on concrete, metal, wood. The composition can be used for interior and exterior coatings, as it retains properties from -30 to +60 degrees, it is resistant to moisture and ultraviolet light.
The liquid form is used for horizontal surfaces, thick - for vertical ones.After hardening, the glue is sanded and polished. An adhesive is prepared according to the instructions before starting work.
General rules for using glues for working marble and granite
The rules for using adhesives for natural stone differ depending on the place of facing. The general rule is to prepare the workplace and the equipment. They are cleaned of dust and dirt. The amount of adhesive should match the surface of the stone slabs to be bonded.
outdoor work
Exterior coating works are carried out with cement and epoxy compounds. Both types of glue are prepared just before gluing. Water or latex is added to the dry mix, and the hardener is added to the epoxy resin in the proportions indicated by the manufacturer.
It is necessary to use the adhesive within the specified time. The adhesive remaining over time loses its properties. You cannot add new portions to it and mix.
Internal work
Interior walls can be concrete, plaster, brick. Before proceeding to gluing, they must be cleared of paint, wallpaper. Floors and walls are checked with a level so that the stone slabs do not protrude above each other.
Additional tips and tricks
Epoxy and polyester glues are harmful to the skin. When working with them, you need to protect your hands with gloves. Cement mixes generate dust when agitated, lifting the smallest particles of cement and gypsum into the air.
To avoid getting into the lungs, it is necessary to prepare the glue in a respirator.
Different adhesives are used to create marble and granite coatings. The surface of the marble will stain if the adhesive contains dyes or salts. Granite has less porosity and does not require special care when choosing an adhesive.
Marble for exterior cladding is used in the climatic conditions of subtropical regions. In temperate zones and further north, it quickly loses its attractive appearance: it loses its color (dark), becomes dirty and cracks with frost. In cities with significant industrial and automobile emissions, it begins to crumble. It is imperative to impregnate marble surfaces from time to time with water and dirt repellent agents. After laying, granite does not require such protection if there is no constant humidity and pollution.
The thickness of the layer depends on the type of adhesive and the facing method. Liquid epoxy and polyester compositions are applied no more than 1-2 millimeters, semi-thick - up to 3 millimeters, thick - up to 4 millimeters. The layer of cement should not exceed 1.5 centimeters.
