Before starting to finish drywall constructions, whether it be arches or cabinets, it is necessary to decide whether gypsum cardboard should be primed before puttying. Typically, preparing walls for drywall almost does not imply the need to solve such complex issues, but preparing the sheets themselves for finishing can cause a lot of discussion among specialists. The debate about whether there is a need to be primed before puttying, wallpapering or staining, arises at least at least.
Do I need to prime drywall
When the question arises as to whether a primer is needed for drywall before subsequent plastering, a lot of controversy arises. Some argue that only the fastener caps and seams need to be primed, others have the belief that it is worth processing the entire surface. There is a statement that you can do without applying a primer at all.
As practice shows, the best result can be achieved if plasterboard is treated over the entire area. There are several reasons for this. Firstly, the primer can improve the adhesion of materials, reducing the consumption of glue, if you are going to paste the wallpaper. Secondly, when you decide to stick new wallpaper, the primer will provide an easy removal of the old coating. Otherwise, it will be quite difficult to separate the wallpaper, and sometimes they go away with drywall, you have to change not only the finish, but also the gypsum board sheets. If you plan to paint drywall, then with the help of a primer you can exclude the absorption of paint, it will be applied evenly and eliminate the formation of stains and stains.
The choice of composition for priming drywall
If you decide that it is still necessary to prime the drywall sheets, go to the choice of mixture. There are several points to pay attention to. The manufacturing company is important. It is not recommended to give in to temptation and acquire unknown soil, the quality of which may be desired. Pay attention to the manufacturer's recommendations. In the instructions you can find out the purpose of the soil. Those mixtures that are intended for outdoor use are not always suitable for indoor manipulations, because the composition may contain substances that are harmful to human health. However, when deciding whether it is necessary to prime drywall before puttying, you can find mixtures among a huge range of products that are universal and suitable for all types of work.
The primer can be tinted in pink or blue, do not refuse to purchase it. Manufacturers paint the compositions for ease of use so that the master sees the unprocessed areas. The color of the primer will not affect the hue of the topcoat, because after drying the mixture becomes colorless. It is important to remember when choosing a primer that too cheap, in comparison with other products, may seem of inadequate quality.
Features of the processing of drywall primer
Now you know if you need to prime drywall before puttying. Once you have selected the composition, you can begin to work. It is more convenient to do this with a roller on a long handle, and for hard-to-reach corners, a brush is suitable. You will need a special pallet with a ribbed surface where the mixture is poured, the master should use safety glasses that are worn even before starting work. If a finishing coating, such as a laminate or parquet board, has already been laid on the floor, then the surface should be covered with plastic wrap before priming.
The drywall primer is applied to the entire wall area, even the smallest areas should not be excluded. It is advisable to do this in two layers, each of them should dry well. If the primer is applied to the finishing putty, do not do this until the surface is sanded. Otherwise, sanding the surface will be impossible. Finishing is possible only after the primer has dried, the full drying period is usually indicated in the instructions.
Suture Processing: Preparation
When grouting is necessary, the drywall surface should be prepared. The master needs to make sure that the docking places are tightly attached to the frame. Each screw should be screwed into the surface to a depth of 1 mm, while cardboard should not be damaged. Next, the base is cleaned of dust and dirt, because the quality of the joints and the durability of the structure will depend on this.
Putty of drywall joints involves the preparation of the sheets themselves, or rather the end parts. Some experts believe that they need to be cut at an angle, which helps to increase the strength of the seam and makes embedding convenient. Others recommend to exclude this process, as they believe that the narrowing of the edges was performed by the manufacturer, and this is quite enough.
Mixture preparation
Sealing the joints in the next step involves the preparation of putty. Pour a certain amount of dry composition into the bucket, fill it with water using a construction mixer and stir until smooth. No lumps should be present in it. The mass must not drain off the spatula.
Tool preparation
Before starting work, it is important to prepare tools, among them:
- ready putty;
- putty knife;
- wide brush;
- primer;
- serpyanka.
You must make sure that there are no burrs on the seams, if necessary, you need to get rid of them with a wide brush. The seams are smeared with protective soil, leaving it to dry completely, at the next stage, you can proceed with embedding. A little mixture is collected on the spatula, which must be added to the joints, spreading along. A serpyanka is placed on the seam and leveled with a spatula. The tape should be drowned in bulk. Sanding can only be started after the surface has dried. You need to polish the seams with a grout mesh or sandpaper. The surface should be smooth, the seams are smeared with a primer again and left to dry.
Primer cost
The primer is acrylic, the price of which is 40 rubles. for 1 kg, it is offered for sale by the manufacturer Brozex. This composition is completely ready for use. On sale you can also find the Bolars primer, for 10 kg of this composition the consumer will have to pay 520 rubles. This acrylic primer, the price of which is reasonable, is a means to strengthen the bases of normal water absorption. The primer fixes loose, old and highly absorbent substrates. It can be applied before further use of adhesives, paints, putties and plasters.
How to choose drywall
If you are thinking about the question of which drywall is better, then you should initially understand its varieties, on sale you can come across:
The first variety is a traditional drywall, which is used for decoration of office and domestic premises. The humidity and operating temperature parameters of drywall do not exceed permissible norms. Humidity for using a wall of such material should not exceed 70%. The second type of drywall is a fire-resistant material, which has a high resistance to flame. As for GCRF, this is a moisture-resistant drywall, which has antifungal components. The latter variety is considered moisture resistant and fire resistant, combines the properties of the above materials.
Wallpapering on drywall
In order to stick wallpaper on drywall, you should prepare the surface, primer it and seal the seams. Initially, it is necessary to put vertical marks on the wall that correspond to the width of the roll. Marking will determine the total amount of material. Wallpaper glue is recommended to be applied with a roller. First, it is applied to the inner surface of the wallpaper, then a wall is rolled. It is better to stick wallpaper on drywall with the help of another person. It is recommended to stick the sheet from top to bottom, leveling it from the center line to the edges.
Conclusion
When deciding whether it is necessary to prime drywall before puttying, it is worth paying attention to the financial issue. Due to the fact that the cost of the primer is not so high, and its consumption is low, the acquisition will not significantly affect the cost of repair.
