Waterproof coatings are favored in many fields because of their excellent protective properties. According to the author's understanding, there are many kinds of waterproof coatings in the market, such as two-component polymer waterproof coating, one-component polyurethane waterproof coating and so on. However, how to choose high-quality waterproof coatings is believed to be a problem for many consumers. In fact, according to the nature of the points, the market in the sale of waterproof paint can be divided into four types, their performance is different, but also have their own advantages and disadvantages.
Hard mortar: waterproof effect on the back surface of the coating
Hard mortar, also called rigid mortar: The ratio of emulsion to mortar is 1:4. After coating, it is not necessary to treat the coating. It can be directly tiled, which is more convenient. After solidification, it forms a cement block, which does not cause water seepage. Its back surface has good waterproof effect and is its biggest advantage. The disadvantage is that this kind of mortar has high hardness and is easy to crack with the deformation of the base layer, so it is generally used for waterproofing the back surface. Price: 200-300 yuan / barrel, a bucket of 18 kg, can brush 10-13 square meters.
Flexible mortar: Cracking does not affect the waterproof effect
Flexible mortar: The ratio of emulsion to mortar is 5:4, and it has elasticity. Even if the base layer deforms and cracks, it will not affect the waterproof effect. It is mostly used on the surface of water, such as wall surface and ground surface, but it cannot be used on the back surface of the top surface. If waterproof is not done well, there is water penetration and it is easy to make water seepage. Price: 300-500 yuan / barrel, a bucket of 18 kg. There is also a type of silicone-based waterproof coating in flexible mortar, which belongs to high-grade flexible mortar. The elastic tension and flexibility are good, but the price is 600 yuan/barrel, which is relatively expensive and very rare on the market.
Acrylate: Long time soaking does not affect function
Acrylates: Pure liquids, ready to use. Water-based, can be melted in water, it is easy to combine with the gap in the ground to form a strong waterproof layer, waterproof effect is better than flexible mortar. After brushing, it is necessary to perform surface treatment such as pulling or sanding to increase the friction and make it easier to tiling. Due to its excellent waterproofing effect, flexible mortars and acrylates are more suitable for long-term flooding. Price: 300-500 yuan / barrel, a bucket of 18 kg.
One-component polyurethane: flexible indoor and outdoor use
One-component polyurethane: Both indoor and outdoor use, brushing is very thick, about 3 mm or so, and the elastic tension is more than 300%, it is very elastic, cracking of any substrate will not make it crack, waterproof effect is the best. Although the safety performance control is among the environmental protection requirements, the odor of such a waterproof coating is relatively large, and it is difficult for most people to accept, and the environmental performance of a few brands is not up to the standard. Polyurethanes are colloidal and are very thick. The use of scrapers during construction is laborious and complicated. After brushing the paint, it is necessary to perform surface treatment, pull the hair or lift sand to increase the friction, and easy to tiling. Price: 500 yuan / barrel, a bucket of 18 kg.
Waterproof coating knowledge: different in nature and different
In waterproof coatings, the difference between 'one-component' and 'two-component' is that mortars are two-component polymers, that is, the ratio of emulsion and mortar; acrylate and polyurethane do not use mortar, it is Single component.
In addition, the drying speed of these paints is affected by the weather, and the drying speed is slower in a cool-climate climate, but the climate has no effect on the waterproof effect. In general, mortars have a drying cycle of 24 hours and acrylics and polyurethanes have a drying cycle of 24-48 hours.
Windows are more than just openings in walls; they're portals to the outside world, sources of natural light, and crucial elements of architectural design. Let's explore the various types, features, and benefits of windows.
Types of Windows:
-
Single-Hung Windows: Consist of two sashes, one fixed and one movable, allowing the bottom sash to slide up to open while the top sash remains stationary.
-
Double-Hung Windows: Similar to single-hung windows but with both sashes operable, allowing for better ventilation and easier cleaning.
-
Casement Windows: Hinged on one side and open outward with the help of a crank, providing excellent ventilation and unobstructed views.
-
Awning Windows: Similar to casement windows but hinged at the top and open outward from the bottom, offering ventilation even during light rain.
-
Sliding Windows: Feature one or more sashes that slide horizontally to open, making them ideal for tight spaces or where a projecting window might interfere with outdoor activities.
-
Picture Windows: Fixed windows that don't open, designed to provide unobstructed views and maximize natural light.
-
Bay Windows: Consist of three or more windows arranged at angles to create a bay space, adding architectural interest and expanding interior space.
-
Bow Windows: Similar to bay windows but with a curved shape, creating a gentle arc that enhances exterior aesthetics and interior views.
