Coating knowledge: common sense of choosing interior wall coating for decoration

Core tips: interior decoration, interior wall coatings (commonly known as latex paint) can be divided into water-soluble resin interior wall coatings and synthetic resin emulsion interior wall coatings Water soluble resin interior wall coating is cheap, nontoxic, odorless and easy to construct, but it is not resistant to water and alkali The coating is easy to peel off and turn yellow after being damped It is often used as interior wall decoration coating for middle and low grade rooms or temporary rooms The synthetic resin emulsion interior wall coating has the characteristics of rich color, good adhesion with the base layer, fast drying, scrubbing, safety, low toxicity, convenient construction, easy maintenance and renovation It has become the preferred material for the majority of consumers to decorate interior walls Besides, there is still air on the market Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coatings home news: interior decoration and interior wall coatings (commonly known as latex paint) can be divided into water-soluble resin interior wall coatings and synthetic resin emulsion interior wall coatings Water soluble resin interior wall coating is cheap, nontoxic, odorless and easy to construct, but it is not resistant to water and alkali The coating is easy to peel off and turn yellow after being damped It is often used as interior wall decoration coating for middle and low grade rooms or temporary rooms The synthetic resin emulsion interior wall coating has the characteristics of rich color, good adhesion with the base layer, fast drying, scrubbing, safety, low toxicity, convenient construction, easy maintenance and renovation It has become the preferred material for the majority of consumers to decorate interior walls In addition, there are air purification functional coatings and antibacterial self-cleaning coatings on the market Air purification coating: through physical adsorption or nano photocatalytic purification technology, it can remove formaldehyde and other harmful gases in the air to achieve the purpose of air purification Due to the problems of cracking and mildew in the interior wall, some high-grade interior decoration began to use elastic interior wall coating The "three in one" emulsion paint on the market is a high-grade coating that integrates elasticity, mildew resistance and stain resistance, with good performance, but low market share Pay attention to the following items when purchasing interior wall coating: 1 Pay attention to the product packaging mark For qualified products, their packaging must meet the following conditions: registered trademark; product model and Chinese name; product standard number (including type and quality level); net content; manufacturer name and address; production date and batch number; effective storage period (shelf life); product certificate; brief use instructions and precautions, etc 2, the quality of products should meet the technical requirements of GB/T9756-2009, such as synthetic resin emulsion interior wall coatings, JG/T210-2007 "primers for building interior and exterior walls", etc., and must meet the requirements of national mandatory standards GB18582-2008 "limits on harmful substances in interior decoration materials and interior coatings" Harmful substances in interior wall coating will pollute indoor environment and affect people's health For the products marked with "anti formaldehyde, anti odor and anti bacteria" and other words, they should also meet the requirements of various indicators in JC / t1074-2008 "purification performance of coating materials for indoor air purification function" 3 Choose the appropriate coating type according to the environment Such as kitchen, toilet and other damp parts should be waterproof, mildew proof, easy to wash paint Other walls should be selected with good decorative effect, fine coating, not easy to be powdered, and a certain degree of scrub resistant coating 4 Pay attention to brand selection At present, there are many brands of interior wall coating in the market Consumers can choose imported or domestic famous brands according to their own economic strength Domestic well-known enterprises have relatively perfect quality management system, advanced production equipment, complete inspection instruments, and relatively stable product quality At present, no matter foreign or domestic brands in the market, they are generally series products Different brands and products produced by different enterprises have poor comparability in price and quality The higher the price is, the better the product quality is Compared with domestic products, foreign products have little difference in performance, but the decoration effect is better than domestic products, and the price is relatively high 5 Distinguish good from bad in sense and feel The coating with good quality has no pungent smell after opening the tank, fine and full appearance, mobility, soft color, high and even viscosity, good workability and smooth coating after painting the wall The second quality coating has pungent smell after opening the tank The coating is stratified and can be even only after mixing, especially the color paint often has floating color Some coatings have high viscosity, but no fluidity, poor fullness, and are easy to produce brush marks during construction 6 You can view the inspection report of interior wall coating, and judge the quality of the product from the technical indicators The technical indexes directly reflect the quality of interior wall coating The main indexes are: contrast ratio (white and light color), washability, drying time, alkali resistance, low temperature stability, free formaldehyde, volatile organic compounds (VOC), heavy metals (soluble mercury, lead, chromium, cadmium), etc You can judge according to the corresponding national standards and make comprehensive selection and comparison 7 Pay attention to the shelf life Generally, the effective storage period of interior wall coating shall be indicated on the outer package of goods When purchasing, it must be within the warranty period of the paint If mildew, condensation, caking, precipitation, caking and other phenomena are found after opening, it indicates that the paint has deteriorated and can not be used again 8 Grasp the relationship between product quality and price The production cost of interior wall coating is much higher than that of water-soluble interior wall coating In fact, the so-called "emulsion paint", which has a very low price in the market, is a fake of water-soluble interior wall coating, resulting in poor water resistance of the coating, easy to fall off powder and fall off 9 When purchasing coatings, the construction instructions shall be read carefully Whether the matching primer is needed? Generally speaking, the primer can significantly improve the alkali resistance and other properties If the primer is needed, the matching products of the same brand are preferred 10 Coating construction is also a very important link Construction shall be carried out in strict accordance with the requirements of the product construction manual, and attention shall be paid to the matching of the bottom, middle and surface of the coating 11 The construction environment shall be ventilated If the product has requirements for the construction environment, it must be carried out according to the requirements Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
