Whether new or old building, without depth reason you will hardly get any renovation or renovation. The deep background creates the optimal conditions for applying wallpaper, tiles or colors to a material. All facts about the optimal depth reason and a guide for the application of depth reason or primer can be found here.

Whether before plastering an older wall or to limit the absorbency of the new plaster, Tiefengrund is a true all-rounder. This type of primer is very easy to apply and usually not very expensive. It saves a primer much of the costly wall paint, which would otherwise be simply absorbed. The results are convincing, and it's not just the painter craft or tiler who swears by the use of primer in many applications. Which depth reason for which of your purposes the right pretreatment is, we show here as well as the dry season of different products.

Costs and prices for Tiefengrund

You really do not need a craftsman for the deep reason. You could even work with the Tiefengrund together with your children. Even with the purchase of primer, there is little wrong to do, as most of the products do the job for which you buy the deep reason.

Deep background, primer or primer - there are many terms for it. In many cases today, acrylic primer is sold in commerce, which can be used for many purposes. Both for sanding and porous plaster surfaces as well as for chalking surfaces such as plasterboard or even on tiles. The prices are very different, as you can see in the examples below, but the qualities are quite good, even at low prices. You can find the Tiefengrund under wall primers in the hardware store or online at the relevant dealers.

  • Acrylic Deep Water dilutable (colorless)
    • 1 liter for 6 square meters about 6.50 euros
    • 5 liters from about 16, 00 Euro
    • 12 liters from about 16, 00 Euro
  • Deep primer - especially for gypsum, plasterboard and lime - solvent-free -
    • 5 liters from about 30, 00 Euro

Functions of deep reason

There are two rough subdivisions for the use of deep reason. In the first variant, the primer should reduce the absorbency of the substrate so that paint, wallpaper or plaster can be applied. New plaster, for example, absorbs large amounts of paint or paste. In addition, this uneven absorbency does not produce a uniform coating. The Tiefengrund compensates for this deficiency by moving into the surface and there clogged the pores. It will require less paint and the peeling of wallpaper will also be much easier in a few years to go by the hand.

Tip: You can check an absorbent plaster simply by pouring or spraying water. If the water does not run down the wall but is sucked in directly, the surface must be treated with a deep primer. For example, when wallpapering the paste is just as quickly move into the wall and not connect as desired wall and wallpaper. The wallpaper would fall at the latest when drying.

Wallpapering on the clean plaster can lead to loss of adhesion

However, the second variant, which uses depth primer, is not concerned with absorbent substrates, but on the contrary with the aim of rendering smooth substrates adherent. An important example is the bonding of tiles on old tiles. Tiefengrund is often offered on an alkyd or acrylic resin base and serves as a kind of intermediate layer.

Fixer for the plaster

Especially sandy porous plaster also sucks too strong, also dissolve components of the plaster when painting. Even when tearing off wallpaper, such a plaster can be damaged. The deep foundation then consolidates the plaster later. Similar to a hair gel, the primer attracts into the surface and stabilizes their cohesion. For such a surface, a solvent-based depth base is recommended, as it penetrates significantly deeper into the plaster or the surface and thus reaches more material in the plaster layer, which is then solidified.

Solidify the plaster with the primer

Tip: A very sandy plaster is so porous that sand already sticks to your hand when you just stroke your hand over the wall. Such sand plasters necessarily require a pretreatment with a high-quality deep ground. In most cases, an application here is not enough and you have to pass at least two layers of deep background. This becomes visible when the deep background dries immediately on the wall and draws in when painting.

Colored deep background - visible primer

For some applications there is depth reason that is colored. This will help you to see where you have applied the primer. However, whether this depth reason makes sense for your purposes also depends on what is to be applied later on the deep ground. If only a very light thin paper wallpaper is glued to the primer, the colored portion could possibly penetrate and discolour the surface.

Apply primer

The advantage of a colored deep background lies in the recognizability of the surface texture. If a surface is particularly porous or uneven, you will see after applying the colored deep ground, where the plaster still draws heavily. There, the colored primer is then barely visible and you should once again apply Tiefengrund. It should be applied as often as deep ground until the surface is evenly colored.

Tip: Pigmented primer should be applied primarily in the base color of the subsequent coat to compensate for color differences in the substrate. In fact, such a deep background resembles more a primer than a liquid deep ground.

Deep primer - solvent-based or water-dilutable ">
Deep background solvent-free

Tip: Since a solvent-free primer does not offer the same results on particularly absorbent surfaces, such as a solvent-based primer, you can achieve a better result with the new microemulsions. However, as is often the case with new developments, the microemulsions are also a bit more expensive than a normal depth.

The solvent-free deep primer can be used both inside and on outside walls. There is therefore basically no reason to use the solvent-based primer except very loose sandy plaster.

Instructions - Apply Tiefengrund

Most products can be applied with both a quast and a painting roller. Be sure to use the device you are most comfortable with. When applying Tiefengrund on the ceiling but bear in mind that Tiefengrund is usually very fluid.

Begin primer on the ceiling

Preparation of the surface

Loose plaster or peeling paint must be carefully removed before applying the primer. If any glue or wallpaper remains on the wall, they must also be completely removed. Paste or chalking surfaces can be thoroughly washed off with a thick sponge. Most manufacturers also point out that the surface must be free of oil, grease or efflorescence.

Tip: The plaster in a new building or plaster in general, should dry out at least four to six weeks before the primer can be applied with primer. In summer, drying is faster than in winter. If necessary, you can check the degree of moisture penetration with a moisture meter.

Prepare for deep reason

If you only bought one liter, you can easily shake the product in the bottle. Otherwise, the primer is thoroughly stirred with a stir bar from the painter's need in a bucket. Read the manufacturer's instructions carefully. Some products are concentrates and should be diluted with water in the specified amount.


Tip: Even Deep Solvent without solvent can leave ugly gray spots on surfaces. Window frames, door frames and the like should be covered with painter's tape and foil. If you do not want to renovate the floor right now, it is better to lay out the painter's fleece. On film, you would slip too easily if moisture drips on it.

Apply primer

Always start at the top of the walls. If the room ceiling also needs to be painted with primer, you should start here. Liquid primer drips quite heavily and by working from top to bottom, automatically dissipate spilled remains.

Mask off the light switch

Tip: The deep background should indeed be applied relatively "full", but he should not run from the wall. Especially on the ground, too abundant an order can lead to puddling. If the soil is to be treated later with a liquid product, this excess binder will cause problems. For this reason, apply only a small amount of deep ground at ground level.

If you apply a solvent-based primer indoors, it is important to ensure good ventilation of the rooms. In addition, sensitive persons should wear a breathing mask so that less of the solvents are inhaled. In addition, it is important to ventilate the room again and again in the weeks after.

drying times

The drying times at primer are quite different. You should therefore read the instructions of the manufacturer. However, there are also various applications in which wet is worked in wet and the next layer is applied directly to the wet depth. But these are rather exceptions.

When processing and drying time, always observe the manufacturer's instructions

Here are some examples of dry times of Tiefengrund:

  • Acrylic deep ground for many purposes - about 4 hours
  • Deep background for plasterboard - about 2 to 3 hours
  • Deep background on tiles - about 6 to 10 hours

Tip: As the drying time always depends on the absorbency of the substrate, you should rather be patient and finish the surface the next day. However, if you notice that the primer immediately disappears into the wall, you should apply a second layer of deep foundation directly. Then you only have to wait once for the dry season.
