If you hear the “empty” sound of the rock slab, you must try to repaint it.
11 joint filling and clean rock slab paving can be carried out 24 hours later.
3 preparation for rock slab paving rock slab handling in order to facilitate handling, it is recommended to use a frame with suction cups for handling, so as to avoid twisting and breaking of products.
The specific construction steps are as follows: ① the mortar of the leveling layer shall be mixed with dry hard cement and coarse sand in the ratio of 1:4 (the dryness of the mortar shall be kneaded into a ball without loosening, and the sand must be coarse sand).
Or use Mabei self leveling mortar for leveling, with higher flatness.
On the contrary, if the ceramic tile glue does not fall down, it will be completely mixed.
Before moving, ensure that all suction cups are fully pumped, and the red line of the built-in pump is in the pump, and then start lifting.
It is specially designed for indoor ceramic plate and rock plate paving.
Before installation, the state of the ground must be detected and the stains such as base ash and oil must be removed to avoid affecting the adhesion of ceramic tile adhesive.
Too thick ceramic tile glue is easy to fall off in the later stage.
Extra care must be taken in this process.
8 use of vibrator and rock plate racket in order to ensure that the rock plate is completely bonded to the base surface and squeeze out all air, please use vibrator or anti rebound rubber plate to smooth the surface of the rock plate.
After tidiness, install a leveler at the edge of the rock slab.
③ Apply cement mortar with ash knife.
Walking and washing are prohibited within 24 hours after construction.
2 ground leveling treatment if the ground flatness does not reach the deviation of ± 3mm, it needs to be re leveled, and the leveling layer shall be moistened and cured with clean water after 12 hours of initial drying, and the curing time shall not be less than 7 days.
④ Use leveling guiding rule to scrape the cement mortar to be consistent with the height of ash cake, and ensure that the thickness deviation is within ± 3mm.
7.
Special attention shall be paid to the breakage or corner damage of the rock plate during handling.
After mixing, use an electric mixer to mix evenly, and use an ash knife to take part.
It is recommended to press from the middle of the rock plate to all sides in the same direction as the scratch of the adhesive, that is, parallel to the short side, so as to ensure that the air between the rock plate and the base surface is squeezed out.
Benefits of Scraper Application: 1 Improve construction efficiency two Save material three Save space four Reduce the hollowing rate.
Today, Xiaobian will popularize our new product – the construction process of 10000 ton rock slab paving! Paving construction flow chart tool for paving rock slab 1 base surface inspection and treatment rock slab can be paved on the common base surface in the construction industry.
9 leveling treatment insert the base of the leveler every 60cm around the edge of the positioned rock plate, insert the leveling wedge and clamp the leveler after checking the flatness, adjust the surface flatness of adjacent rock plates, and adjust the gap between rock plates to about 2mm for subsequent joint agent treatment.
After the joint sealant is solidified, the excess joint sealant shall be cleaned to keep the surface of the rock slab clean.
The sponge joint scraper can be used to beautify the joints of the rock slab.
4.1 what is the mortar product made of ceramic tile adhesive, selected high-quality natural inorganic mineral raw materials, crystalline masterbatch and polymer additives, which can be used after mixing with water.
After completing the above processes, the whole paving operation steps will be completed successfully!.
Rock slab is a new type of multifunctional building material, which has a wide range of applications and strong overall decoration effect.
On the other hand, the adhesive is applied on the back of the rock plate with a scraper with small teeth (square teeth with an interval of at least 3-4mm), so that the back of the rock plate is fully coated.
12 finished product protection in order to avoid scratching the rock plate in subsequent construction, the ground needs a protective film (the simple one can be replaced by the rock plate carton), and the corner of the wall needs to be protected with a protective sleeve.
Its super bonding force makes the paving of low water absorption ceramic tiles, ceramic plates and rock plates more durable and firm.
The adhesive must be applied in the same direction on the base surface of the back of the rock plate (coated with adhesive) (parallel to the straight line of the short side of the rock plate).
The uneven or rough surface can be troweled with cement mortar, and the construction base surface shall be fully wetted to prevent hollowing.
5 Application of scraper use a scraper with inclined notches (spacing of at least 10mm) to apply the adhesive on the base surface so that the adhesive is evenly distributed on the base surface.
At this time, the wall and brick surface can be painted and scraped.
10 empty drum inspection after paving for one hour, gently tap the plate surface with a small hammer to check whether there is empty drum.
② Use the infrared level to locate the leveling line and hit the ash cake as the leveling point (generally, the leveling layer is 3 ~ 4cm thick).
6 the application method should be to apply the adhesive in a straight line parallel to the short side of the rock plate, not in a circle, so as to reduce the air generated by extrusion during pasting.
After the adhesive is applied and scraped on the ground and the back of the rock plate, use the rock plate lifting bar to lift the rock plate to the paving area, adjust the position and slowly bond with the ground, and move and adjust the paving position when it is not fully adsorbed.
The interior of the base surface must be kept flat.
It is super flexible and can well adapt to the slight deformation of base surface and ceramic plate; It can be used for the base surface with slight vibration and is not easy to shrink.
It can cut a variety of specifications freely to meet the needs of personalized space design! However, the construction problem of rock slab has been bothering the terminal stores and consumers.
4.3 preparation of ceramic tile glue according to the different requirements of different brands of ceramic tile glue, it is necessary to see the instructions behind the bag, especially the mixing ratio of water and ash.
If cement paving is used, it is easy to cause hollowing due to low bottom adsorption capacity.
② The thickness of ceramic tile glue should be 5-7mm.
4.2 tips for ceramic tile glue preparation ① during the construction of rock slab paving, professional back glue and ceramic tile glue must be used instead of traditional [cement], because 10000 tons of rock slab raw materials have high purity, high density and extremely low water absorption (double 0 absorption all ceramic).
