The filler for joints - reanimate the construction sites

Construction joints - what are going to fight?

In general, the construction joints can be divided into groups:

• in concrete structures;
• in ceramic tiles and finishing;
• waterproofing (bathrooms, saunas and swimming pools, the junction of the roof, ventilation, piping);
• in windows and doorways.

Each type of compounds has structural problems, and the material used for the sealing of joints is different.Concrete floors and waterproofing sealants are used for decorative tiles - grout, and for windows and doors - foam.Size matters: for joints less than 3 cm and grout applied sealants, more than 3 cm - foam.

Sealant - the most popular filler for joints

Sealants - this polymeric materials, they are single and multi-component curable and there, their main quality - elasticity.As the base material are silicone sealants, acrylic polymer and bitumen.For concrete joints is mainly used silicone sealant.

Any building undergoes deformation, causing its differential outdoor temperatures, humidity, ultraviolet radiation, ground motions and movement techniques.Parts of the building are moved in different directions, and in places of potential design tension cracks are perceiving elastic deformation.

destruction is not included in the operating plans of the building, so the cracks should be repaired as soon as possible.They fill the prepared fiber and silicone sealant.Encapsulation also protects joints against ingress of water and corrosive liquids.

Silicone sealants are available with anti-fungal additives, it is convenient to use the toilets, baths and showers, they prevent the appearance of mold.Acrylic sealant sealed inactive compounds, and it is the best way to seal cracks.It is only suitable for outdoor use, the cold hardens and loses its plasticity.

Polyurethane Sealants façade called for suitability for outdoor use and high adhesion, due to which the sealant is kept in a vertical seam without dripping.They easily withstand deformation, do not lose their properties against heat and cold, painted in any color.

Bituminous Sealants in the home called the roof, their proper name - Thiokol.The basis of the bitumen allows them to adhere well to moist surfaces, they are well to seal cracks in the foundation and exterior walls.

Grout and foam - where the use of these fillers?

grout for decorative tiles (or floating) the type of foundations is divided into two types:

• cement;
• epoxy.

grout based on cement contains more silica sand and mineral plasticizers, used for interior and exterior use.Some cement grout is added to the second component - latex, it is mixed independently.In this case, the grout can be used for swimming pools and saunas.

two-component epoxy grout initially gives an impermeable seam is very durable, used for exclusive design.A mixture of grout chosen depending on:

• of the coating.Cement grout do not use on limestone, PVC, wood, epoxy - on porous stone and brick;
• weld size, this option is specified on the label of the grout;
• operating conditions, if necessary, use special impregnation over a cement grout, glass-epoxy is used in the most expensive design.

When the amount of cracks more than 3 cm foam used to seal joints that can expand during solidification.The foam fills all, even invisible cavity and solidifies to form a porous heat and sound insulation material.Foam is summer, winter or all-season, to protect it from ultraviolet radiation can be putty or decorative ribbons.
