Prime the plaster thoroughly before painting - DIY instructions
- Three variants for a primer
- What primer choose "> Rigips in wet rooms
Today, plasterboard is one of the most important materials in drywall construction and is mainly used in the area of floor planing and the redesign of residential areas. Before painting or applying a wallpaper, you should pay attention to the primer and treat the surface accordingly. Here, the reader learns helpful tips and measures on how the drywall is used as an optimal substrate for wallpapers and paints and what preparation ensures precision in the surface treatment.
Primer provides for plaster walls for a uniform and lasting adhesion of the paint. It is imperative to prime the gypsum board with a primer before painting and to prevent the paint or applied plaster from drying or crumbling unevenly when the moisture penetrates into the plasterboard. For priming there is not only one possibility, so that the do-it-yourselfer can make the basis for further wall processing dependent on his personal possibilities and the subsequent processing of the surface. Gypsum plasterboard is very absorbent and is one of the materials with special sensitivity to external influences. This has an effect on the treatment of the surface and, if the primer is not applied, can contribute to the color becoming spotty, friable or uneven and not optimally holding. Priming yes, but how? Here, the do-it-yourselfer learns important information about priming and the necessary preparatory tasks for walls in drywall construction.
Advantages of preparation by priming:
- The surface is restricted in its suction behavior and absorbs the paint, the plaster or the wallpaper paste evenly.
- Too fast drying of the paint is avoided, whereby the result is more intense and stain-free when painting.
- You need much less material and saves yourself unnecessary additional costs.
- The joints between the wall panels made of plasterboard are compensated in the suction behavior and do not appear visible after painting. This means that there are no visible transitions between the plasterboard panels and thus no color differences on the wall.
- If a wall is made of plasterboard and masonry, the different material properties are counterbalanced by priming and the finished result does not reveal where the concrete, brick or plaster wall paint is located.
Three variants for a primer
Different ways lead to the goal in the dry construction and give the chance to choose between different measures with the priming. Thus, the primer can be applied with a special deep base or diluted wall paint. The use of Tiefengrund best balances sensitivity to external influences and is one of the most common applications in drywall construction because of its simplicity and effective effect.
Since there are different depth reasons, you should focus on the selection of the subsequent wall processing and choose a design that harmonizes with the wall paint or wallpaper paste and supports its adhesion. The primer with diluted wall paint is especially recommended if the wall is subsequently painted and not papered. The costs are lower than with Tiefengrund and it takes less working time for the application. With plasterboard, this method works very well, as dilution gives sufficient moisture in the wall paint and the plasterboard can not completely absorb the primer. Alternatively, one can also rely on the benefits of drywall paint and use this for the primer.
You need this:
- or diluted wall paint
- or drywall paint
- a painter role
- a bucket
- a device or a wooden stick for stirring
- a drip filter from the painter's supplies
Wall paint for priming is the cheapest and time-saving option. However, the result is only suitable for pure rigs and not to compensate for material differences. Deep reason is relatively expensive and requires that you include an extra step in wall processing. Accordingly, you pay more here in priming more money and must expect more time to the finished wall. Ideal is drywall paint, which is especially suitable for preparing plasterboard for later processing. Primer and paint are applied in one step and you save time, while you have to accept a higher financial cost.
What primer choose ">
If you want to save time in the first place, the drywall paint is very well advised with variant three. Even if paint and primer are done in one step, you still have to spend more money on the plasterboard.
More time-consuming but cheaper is the primer with paint, which is applied well diluted with a 10-20% water before the actual puncture. This method is only suitable if the wall is completely made of plasterboard and has small joints. If widened joints or different materials on the wall are made evenly, a treatment with diluted wall paint is unsuitable.
Not always a plasterboard wall should only be painted. If the application of plaster is planned or if the wall is to be wallpapered, Tiefengrund offers itself as the best preparation of the Rigips surface. Deep priming reduces the absorbency the most, whereby the plaster or paste of the wallpaper can adhere to the surface. Especially with heavy wallpaper and textured wallpaper you should not give up on Tiefengrund and refrain from priming with diluted paint or special plasterboard color.
Ultimately, it can save you time and money by reading the back of the offers and getting an overview of what preparation is optimal based on further processing. Pure Rigips without primer can be painted, plastered or wallpapered without any problem. The properties of plasterboard are responsible for the fact that you should always work with a primer in dry construction and thus prevent the absorption of moisture in the plaster.
Rigips in wet rooms
The sensitive material plasterboard should not necessarily be used for wet rooms. If a bathroom or the kitchen is divided and decorated with plasterboard in the room, you have to give the primer even more attention than for example in the room division in the living room or bedroom. The sole treatment with wall paint is not sufficient to compensate for the high humidity in the room and to protect the drywall from damage caused by moisture. For wet rooms, deep priming and a subsequent waterproof surface treatment is the only measure recommended for Rigips and which lends itself to the desired result in the surface design and liability of wallpaper and plaster.
Do not underestimate the time required
For cost and time reasons to do without a primer is not advisable. Rigips is a practical material that shortens the construction time, but it has a very sensitive property and should therefore only be used indoors. Priming extends the life of a plaster wall and precludes drywall from being damaged by contact with moisture and replaced after a few years.
Gypsum boards are usually covered with a very thin layer of paper, which does not replace wallpaper and should not be considered as a primer. If the wall is to be plastered later, one selects gypsum boards without the paper layer, which would become detached during the application of deep ground and would become an uneven result of the surface.
Those who devote themselves to preparation with patience and the necessary time will enjoy their drywall construction and will not be able to design their house or apartment without pulling concrete or brick walls with a new layout. Also for hanging ceilings or wall compensation plasterboard is a popular and practical building material. After priming and the necessary drying time you can make the wall as desired and rely on optimal adhesion and rich colors on the surface. If you save that time, you can save at the wrong end and can expect that the construction site will reopen after a short time and ultimately have to start over with the wall treatment again.
With Rigips you can design rooms freely, hang ceilings, cover walls or set accents. Gypsum is a very moisture-absorbent material, which must be protected accordingly from external influences and contact with too high humidity. This is done in drywall by means of a primer, which provides the necessary roughness of the surface, for the reduction of the absorbency and a simpler application of colors or wallpaper. Gypsum plasterboard can be primed in three different ways. Therefore, it is advisable to compare the different substrates that are suitable for paint, plaster or wallpaper, which simplify reworking and support the positive properties of the plaster walls.
