The biggest mistake in finishing drywall, and how it can be avoided

INsho often in the interior decoration of country houses builders began to use plasterboard sheets (GCR) instead of traditional, familiar to all even with the 90s lining.

Dipsokarton refers to the so-called "Dry Technology" which are very easy to install: plasterboard is manufactured in the form of sheets and attached to the pre-prepared core systems.

However, ignorance of important nuances of working with GCR is able to block all the advantages of this material.

gypsum plasterboard - a layer of dry gypsum, pasted on both sides with sheets of cardboard, and the weak spot GCR is that it is exposed to moisture.

Gypsum has a porous structure that on the one hand allows the walls to "breathe", but on the other hand - and absorb moisture to pass through itself.

PWhen building this is often forgotten, especially since the consequences of negligence occur no earlier than a year.

EIf a sheet of drywall is hidden insulation (mineral wool), then he is sure to dampen and insulate lose their properties. If the insulation is not present, then the moisture will pass directly to the outer walls, and

lose heat.

How to avoid it?

1) When placing plasterboard on the floor, pour into the cellar natural thermal insulation - expanded clay or sand (with a moisture content of up to 1.5%). Filling with expanded clay is very simple and very cheap concrete block, the only requirement - insulated concrete block on the ground.

2) Mounting a plasterboard on the vapor barrier wall is required to stretch the film or membrane between the insulation and the sheet of drywall.

3) The general recommendation is All manufacturers GFC is a constant monitoring of moisture levels in the room - in other words, ventilate the room, paneled GCR often.

Ence the opinion that the above problems can be easily solved with the help of water-resistant gypsum board, but this stuff I never used, and can not say anything about it.
