Worth knowing about moisture barrier and fog masses in bathrooms

Building a bathroom from scratch is done in layers of layers of different layers. Fluid pack, moisture barrier, sealant, primer, fix and joint are needed. Everyone has their purpose, from the protection of moisture to the tiling of tiles. Without one of the parts, the bathroom can not be considered completely built.

Tiled wet rooms make high demands on walls, floors and ceilings. Here, both layers are needed that protect the rest of the house from moisture as well as firmness and joints to make the plates sit and provide a smooth and easily cleanable surface. All components are equally important for a durable and beautiful final result.


The walls in a bathroom can consist of special plasterboard or concrete. On this surface a primer is laid on walls, floors and ceilings. The primary purpose of the primer is to ensure that the moisture barrier that is laid attaches securely to the walls. After the primer is laid, the floor is then flattened with a slope towards the floor well. The flypack also provides a smooth and stable surface to lay.

The moisture barrier

After primer and float package, the so-called moisture barrier is applied to all surfaces. In order for the moisture barrier of the room to become completely tight, reinforcement of the moisture barrier is necessary for the floor wells, corners and drainage pipes. These reinforcements consist of cuffs that can be purchased in the construction industry. Two to three layers of moisture barrier are needed to get the wet space really tight. Finally put a sealant on the moisture barrier. Also, it often needs to be added in several layers.

When does the moisture barrier not need?

A moisture barrier is a necessity in all bathrooms and wet areas to be tiled. However, not all seat mats and plastic walls need a moisture barrier behind them. Some space mats are counted as moisture barriers in themselves. They act as surface layers and moisture barrier in one. There is even the possibility of tipping on such plastic mats.

Bathrooms below ground level and which have penetrating soil moisture should generally not have any moisture barrier. The dense layers sometimes cause more harm than goodness. In such bathrooms, only primer should be used. Here a professional should really help create a good wet space.


Below the tiles, a warehouse is added. The fix is ​​a pulp that causes the tile to cling to the wall or the floor. The fix should be vertically laminated to form slats that the water can drain downwards if it gets damp behind the plates.

Variants of Fixed

There are fixes for both floors and walls and fixes that are only made for one of them. Different fixes also tolerate different stresses. If there is heat in the floor, the fix must be heat resistant to be durable. Large tiles and mosaics need special fixes. The large plates can be set with float fixings, while so-called superfix is ​​suitable for mosaics. There is also a fix for transparent mosaics. It is called white fixation.

Fog mass tile

The tile joint for tiles is the material between the plates. It is designed to provide a smooth and good finish and acts to protect the plates, not to counteract moisture in the first place. It makes the moisture barrier. The joint mass comes in several different colors and can therefore be matched to the plates. White tiles need a darker joint, while dark tiles appear beautifully with a lighter joint.

Fuse massages

Fuse is also needed to protect the ends of the worktops against tiles and other joints from becoming damp. There are different joint masses for different materials and different environments. The joint used for the corners is of a different kind from that used for the tile. This joint must be a very moisture-resistant and durable joint that does not break out at first. The most common joint mass behind the slabs and in the corners of a bathroom is a silicone joint. It should be designed for wet rooms to be suitable. It is a resilient joint that does not break at first. This type of joint can not be painted over.

Tips for Buying

There are several brands of products designed for sealing bathrooms and for tiling. They may have different recommendations as to how these products should be used to ensure best protection. Always follow the instructions very carefully. To get an approved design, all products will come from the same brand. Always bet on high quality. Cheaper products are often worse in the long run.


New material regulations, rules, recommendations and working methods are constantly coming. Therefore, always contact the relevant trade organization / professional before starting.
