What putty is better for walls

The correct selection of the leveling or primer putty is determined by the material of the wall and the specifics of the use of the product. Manufacturers produce a variety of mixtures designed for various works.

Fundamental classification:

Gypsum putty are well aligned and not exposed to shrinkage, it is inexpensive and environmentally friendly, but they are destroyed under the action of moisture and are applied only with internal work.
Cement putty - provide durable surfaces, perfectly opposing water and frosts, are used on facades and in wet premises, lack are prone to cracking after applying.
Polymer sticks based on acrylic - plastic and easily laid mixtures with a wide range of applications, sold in finished form and undemanding to application technology, but have a high cost.
Polymer latex putty - differ from acrylic greater elasticity and stability to loads, apply even on metal surfaces, disadvantage - the resulting "rubber" coating does not let the air.
Oil-adhesive putty are suitable for plastered wooden walls of chulans, kitchens and other rooms, where the finish is more technical, not decorative.

The surface under the putty should be stronger than the applied composition. For example, it is meaningless to use a cement mixture on a loose base - it just falls off. Dry mixes require proper preparation, which largely determines the quality of the surface being separated. Finished putty are divorced in accordance with technology, therefore it is easier to use, but they have restrictions on transportation and storage time.

Separation:

Starting putty - high-strength mixtures with good adhesion and large graininess are intended to align plaster layers up to 20 mm.
Finishing formulations - used for decorative finishing and creating a perfectly smooth layer with a thickness of up to 4 mm.
Universal mixtures - combine the properties of previous varieties, cost more expensive, are used on walls with small defects.
