Characteristics of polymer clay
1) It is a multifunctional, odorless and nontoxic powder material with one component and simple construction. It can be operated only after adding a proper amount of water and mixing well.
2) It can be constructed on wet foundation.
3) Low shrinkage and good water retention.
4) It has the dual functions of waterproof and bonding. When it is used in exterior walls, toilets, pools and other parts that need waterproof, it can be used to stick tiles instead of being used as a waterproof layer.
5) Its internal holes are spherical or nearly spherical closed holes, which will not form connected capillary channels, and have good impermeability, which can effectively prevent water from entering the structural layer or cement mortar leveling layer.
scope of application of polymer mastic
1) It is mainly used to paste various tiles, horses and smooth tiles.
It is suitable for waterproof layers of interior and exterior walls, bathrooms, toilets, reservoirs and so on, which are based on concrete and compressed fiber cement board.
How to use polymer mastic
1. Used as waterproof coating: mix it according to the proportion of mastic: water = (2.5-3.): 1, and then brush it after stirring for ten minutes, with uniform thickness and no omission. After the previous procedure is cured, brush it for the second or third time, with a thickness of about 1.mm, (1.. For some parts with special requirements, glass fiber cloth or non-woven fabric can be used for reinforcement, and the construction process of "one cloth, two coats" and "two cloths, three coats" can be adopted, and the thickness is about (2.-2.5) kg/
m2.
2. Used as a bonding material (also waterproof): mixed according to the proportion of beneficial cement and water = about 1: 3, and can be used after stirring for fifteen minutes. For granite, marble and other high-grade decorative materials, it is not necessary to use old techniques such as drilling holes and hanging nets, but can be directly daubed and pasted like ceramic tiles and other materials, and the thickness of the paste layer should be kept between .5 and 3. mm. The method is the same as pasting with ordinary plain cement slurry, which has super cohesive force and waterproof function.
Precautions for polymer cement
1. The construction base surface must be kept moist, free of Mingshui, clean, flat and firm;
2. After completion, attention should be paid to the protection of finished products, and it is forbidden to destroy the waterproof layer artificially;
3. In ventilated and direct sunlight areas, in order to prevent excessive water loss and pulverization, methods such as sprinkling water and covering with warm materials can be adopted for proper maintenance for 3 days.

○ All small gaps can be stirred into a wet mass by adding water or cement mortar into the powder, and then smoothed. Yin and Yang angles should be painted into circular arcs or obtuse angles in advance.
OLY-531 construction method of OLY-531 beneficial mastic:
It is used for waterproofing (interface layer and waterproof layer) of toilet, kitchen, parapet floor and external wall:
○ Interface layer: a layer of beneficial mastic mortar (about 1-2mm in thickness) is scraped lightly on the cleaned and moist base as a waterproof interface layer, and it should be spread and compacted when scraping.
○ Waterproof layer: After the interface layer is scraped, a layer of beneficial cement mortar is scraped on it as a waterproof layer (thickness is about 2-3mm). The scraping direction should be 9 degrees with the interface layer, and it should be fully paved and dense when scraping.
It is used for waterproof bonding of various decorative tiles:
○ Single-brick bonding: When bonding decorative tiles, you should scrape a layer of beneficial cement mortar (about 4mm in thickness) on the cleaned base surface or brick back, and stick it from top to bottom or from bottom to top according to elastic lines or hanging lines, and then use caulking mud for caulking after the adhesive layer is finally set.
○ Two-sided coating: When the facing is required to be waterproof, the double-sided coating method can be adopted, that is, a mortar with beneficial mastic (about 2-3mm in thickness) is scraped on the surface of the base, and a PA-A mortar with beneficial mastic (about 2-3mm in thickness) is scraped on the back of the tile to be pasted, and the joint is sealed with caulking mud after the adhesive layer is finally set.
Precautions:
○ Lime cement containing lime cannot be directly covered on the coating of this product, and an interface treatment agent must be applied first to enhance the adhesion.
○ Within 24 hours after the slurry is coated, protective measures should be taken to prevent people from walking, getting caught in the rain, frost and exposure to the hot sun.
OLY-531 Normal dosage of Olya-Yi cement:
1 ~ 2 kg/m2, and the actual dosage depends on the smoothness of the base surface and the construction habits of workers.
storage:
stored in a cool and dry place. The shelf life of unopened products is one year.
question 3: how to use the beneficial cement? Make the beneficial cement first, and then make it waterproof. In fact, it doesn't matter whether the beneficial cement is made or not. If your base surface is too rough, you can make it with the beneficial cement first. (Note: it is the ground, not the wall) Then waterproof it twice. It's safe to do some special treatment for the angle of yin and yang and the pipe position.
Question 4: The function of beneficial cement has the following main functions:
1. Improve the bonding strength: The beneficial cement uses polymer compounds as water-retaining agents, so that the water in the cement base material is not easily absorbed by the bonding materials, so that there is enough hydration time and the bonding strength is improved.
2. Extend the correction time: Because the polymer-beneficial mastic uses polymer compound as water-retaining agent, it has strong water-retaining performance and inhibits the excessive loss of water, so that the correction time can be extended to about 2 minutes at the longest.
3. Improve sag resistance: Slip and sag are caused by the gravity of the cement just constructed on the vertical surface and the tile pasted with its image. Anti-sagging agent in beneficial cement products can improve this undesirable phenomenon.
4. Increase the viscosity of the binder: The polymer thickening assistant added to the product with beneficial mastic has high viscosity, which makes it have good operability.
5. Improve the waterproof performance of the binder: Beneficial clay can reduce the number of capillaries produced during the solidification of cement-based materials and generate many fine bubbles at the same time. These closed fine bubbles can block the capillaries produced during the solidification of cement-based materials, thus improving its waterproof and impermeability by 2%.
Question 5: Is beneficial mastic putty? What's the difference in function? That's not true. Polymer-beneficial cement is a new type of non-toxic and odorless rigid waterproof adhesive material, which is made by mixing a variety of imported polymer materials with a certain proportion of portland cement and silt, and processed by scientific proportioning and special technology. It has the functions of waterproof, bonding and plugging, and belongs to cement-based polymer dry powder waterproof mortar.
And what we usually call "putty" refers to the building decoration materials commonly used by painters and used for leveling walls. Generally, there are: talcum powder, white powder (Shuangfei powder) and finished putty powder produced in factory. Putty is not latex paint. Putty is the basic material of latex paint. In construction, first batch of putty is scraped, and then the latex paint can be rolled.
as for the problem of "cement paint", in fact, it is a difficult concept to explain clearly. Some people think that exterior paint is cement paint, but this is not accurate. Exterior paint is not necessarily cement paint, but most of them are cement paint; The diluent of cement paint is not necessarily water, but most of it is water. Cement paint has waterproof (water-resistant) function, and what we usually call "latex paint" refers to one of the indoor wall coatings, which does not have waterproof (water-resistant) ability. Therefore, in this respect, it needs to be determined according to the text description of the paint.
For the term "plastering", it generally refers to the leveling construction of wall surface with cement mortar in civil engineering, that is, the wall surface is painted with cement mortar. This is different from "putty".

question 7: does beneficial cement have waterproof function? beneficial cement is only used as a material for joint repair, and its waterproof function is limited. Generally, matching waterproofing agents are recommended to be used together on the Internet. If you are leaking in the joints of ceramic tiles, you can brush the cracks of ceramic tiles with Helong transparent waterproof glue. If the cracks collapse and are uneven, you can also fill them with ordinary cement or caulking agent before brushing.
question 8: can the mastic be used to paste tiles? If so, can all kinds of tiles be used? Beneficial clay is a common name, which is a local dialect. Its formal name is tile glue. Porcelain tile glue is not suitable for all tiles, but it is divided. The so-called glazed tiles, vitrified tiles, whole tiles, antique tiles, etc. are distinguished according to the water absorption. < P > Question 9: What is the dosage of beneficial mortar and jointing agent? 5 points Under normal circumstances, when the flatness of the base surface is plus or minus 5 mm, the dosage of beneficial cement is about 6 kg, and if the flatness is almost the same, the dosage is about 8 kg.
it covers an area of 17 square meters, with the interior wall area of about 3 times, and the interior wall construction area of about 51 square meters. But smallpox can't be tiled, right? Deduct 17 square meters, which is about 34 square meters for construction. When all the walls are tiled, the consumption of beneficial cement is about 1.5 tons, which is the calculation of one floor. If it is 4 floors, it is about 5 tons. The budget is all the tiles on the wall, which needs attention!
For caulking agent, you need to know the size of caulking gap. If you follow the standard caulking construction, the consumption per square meter is about 2.5 kilograms. I hope it can help you.
