Acrylic sealant - what is it worth to our attention?

Acrylic, sealant - the first acquaintance of

Acrylic sealant is a non-toxic and hypoallergenic polymer building material that is based on acrylic, and is intended for interior and exterior repair work. They are water resistant and not waterproof.

Non-waterproof version is perfect for sealing stationary and inactive mobility when performing interior repair work. Waterproof compounds are used to seal the roof, the outer side of the window blocks, etc. Acrylic frost resistant sealant can withstand temperatures up to -25 ° C.

Acrylic based sealers are quite popular among builders, thanks to a number of positive qualities :

1. easy to use and affordable price;
2. safety( they are non-toxic);
3. excellent adhesion;
4. are not fire hazardous;
5. resistance to UV radiation;
6. possibility of staining.

Features of the application of

If we talk about the shortcomings of acrylic representatives, it is worthwhile to clarify, although the manufacturers and argue that

acrylic sealant for outdoor works is well suited for sealing the roof, it must be used carefully. Since under the influence of changes in temperature and precipitation, the composition on the acrylic base can deform. This is because it hardens in the frost.

In addition, they can not be used in expansion joints with a maximum opening greater than 15%, becausepeeling from the surface may occur. But if you still need exterior sealant, you need an acrylic based sealant, then take an acrylic sealant. It has excellent vapor permeability, adhesion, resistance to UV radiation and atmospheric influences.

Acrylic Sealant - choose what we need

Often when performing internal repair and construction works, you can hear the question: which sealant, acrylic or silicone, is better to use? To answer this question it is necessary, first of all, to know in which room and what works are being conducted. And only then proceed from the characteristics of this or that material.

If the question is about the repair work in the bathroom, then use a better silicone sealant, tk.it is durable, heat-resistant and not hydrophobic. If the work is carried out in other premises, then acrylic sealants are preferred here. Firstly, because of the price, because they are several times cheaper than silicone, and secondly, the silicone compounds do not stain, and you will hardly be able to bring it into the proper form, combined with the design of the room.

You should also pay attention to whether the sealant you are using is filled with or without filler. Those in which there is no filler, after drying, are transparent. This type has increased adhesion, elasticity and price. They are the ideal solution for filling joints with significant linear extensions or as an adhesive.

A filler material( eg acrylic white sealant) is used if the surfaces do not experience linear extensions and are tightly fitted to each other.

Before applying the sealant, you must visually assess the depth of the crack or seam and, if necessary, put a sealant or special cord into it. This is done to save material. After that, the surface must be cleaned, degreased and dried. Sealant to apply a thin layer with a special construction gun( if bought it in a tube).And if it is in a bucket or in a tube, then it should be used with the help of improvised means.
