All construction coatings have passed ISO9001 Paint Home News: now, many people choose to paint their own latex paint, because its process is not complex, can save money, and can experience the joy of labor In fact, there are still some ways to brush latex paint by yourself, and some places to pay special attention to when you brush latex paint by yourself Here's a brief introduction of how to brush latex paint by yourself and the problems to pay attention to when you brush latex paint by yourself, hoping to help you Necessary tools: 4mm long inner wall roller (you can choose professional accessories from Christine or nippon) Brush the emulsion paint by yourself: 1 Mix the emulsion paint with clear water first The proportion of water added for roller coating is generally controlled to 20% to 30% by volume If there is too much water, it is easy to cause poor film formation of the emulsion paint 2 Mix the paint and water evenly and then stand still for 20 minutes to achieve the purpose of defoaming, so as to avoid pinholes or small bubbles after the emulsion paint is on the wall 3 The static time is over It's time to paint First, moisten your tools with water For example, the wool brush and roller at the internal corner should be moistened with water first, and then dip in the material Next, paint 4 The emulsion paint is applied in the way of one bottom and two sides according to the standard process (1) the primer is applied first to seal the body and alkali and increase the mechanical biting force (adhesion) of the bottom and finish paint The process of painting is that the living room is followed by the bedroom, the roof (ceiling) and the wall (2) If you think the wall is not delicate enough, you can use 600 × water sand to gently knock off some small particles on the wall before painting the second finishing coat Remember that the small particles should not be heavy (3) After each painting, paint at an interval of 2 to 4 hours, or feel with your fingers If the paint surface you press with your fingers does not have adhesion (dry with your fingers), it can be painted (4) The position of switch box and door jamb window cover shall be covered with masking paper before painting Masking paper can be bought together when you buy roller and wool brush Note: if you paint by yourself, especially if you paint locally at home, it is recommended to choose latex paint without smell Although it is more expensive, you can move in after painting 1 Pay attention to four points when determining the color - ● on the color board, or even on the paint barrel, the color you see may not be the same as when you brush the whole wall In order to avoid disagreements, the following steps can be taken: do not make the final decision on which color to choose in the paint shop; instead, take the color board or the actual paint sample home, and observe the color of the paint at the wall to be painted; ● observe the color of paint under natural light and night light respectively, because even if the same paint has the same color, under different lighting conditions, the displayed color will be greatly different ● at the same time, remember that when a paint of one color is applied to a large area, its color tends to increase To make up for this, it's best to use a lighter color than you want ● the coating has various glossiness, including "high gloss" and "flat gloss" The paint with higher glossiness has better reflection, so this kind of paint will make the room look brighter But on the other hand, the high gloss coating is easy to highlight the shortcomings of the wall, so if the wall is not very flat, it is appropriate to choose flat paint 2 Choosing appropriate brush tools and tools with good brush quality can brush a thicker coating, better cover the original color of the bottom layer, make the paint film more durable and withstand repeated scrubbing 3 Before hand brushing the wall, the dust and dirt on the wall should be removed with common cleaner or clear water and dried If there is a nail hole in the wall, fill it with filler Fine cracks can be filled with high-quality 100% acrylic sealant 4 Brush a "frame" on the outer edge of the wall with a brush before painting the inner wall with a roller The effective roller coating method is to dip the coating onto the roller to roll out a large "W" or "m" shape on the wall, then fill it up and roll in different directions The interior wall latex paint is an ideal paint for interior wall decoration, which uses water as the dispersing medium, has no organic solvent, explosion, fire and other dangerous problems In the process of decoration, the formulation of interior wall emulsion paint must be understood This issue provides formula information of interior wall emulsion paint for your reference! 1 Dispersant reference: select different dispersant types according to different thickener systems selected; when thickener systems are ASE and hase thickeners, our company recommends CPA, which has excellent thermal storage stability; when Huer thickener is used, we recommend kPa; Our experiments show that the coating produced by CPA and kPa will not have adverse phenomena in the storage process due to the increase of the amount of dispersant; we use CPA with MC35 thickening in the formula of interior wall latex paint, and use kPa with pu40 thickening in the formula of interior wall mercerization, with good effect; 2、 Pigment and filler reference: due to different requirements for gloss and air permeability of the film, the pigment and filler in the formula of medium and high-grade interior wall emulsion paint are generally controlled between 30% and 45% of the total amount of the paint; anatase is generally selected, with the addition amount between 10% and 20% of the total amount of the paint; calcined kaolin: good covering performance, excellent suspension, moisture absorption and impact resistance Heavy calcium carbonate: high whiteness and good rheology; compared with high PVC engineering interior wall emulsion paint, light calcium is generally not recommended to be used in the formula of medium and high-grade interior wall emulsion paint; in the formula of light system emulsion paint, fillers are generally not added (mainly most fillers are dimmed, but from the perspective of cost, we choose to add a small amount of fillers to reduce the cost; the experiment shows that, Among many cheap fillers, heavy calcium carbonate has the least influence on gloss; we use 10% anatase white, 8% calcined kaolin, 22% heavy calcium carbonate in the formula of interior wall emulsion paint, 20% anatase white and 5% heavy calcium carbonate (accounting for the total amount of coating) in the formula of interior wall mercerizing, with excellent performance 3、 Thickener reference in this formula we do not consider HEC Interior wall flat varnish: MC35 and mc201 are recommended for medium, MC35 has strong thickening ability in water phase, excellent fluidity and excellent medium shear viscosity, which is the best low-cost alternative product of HEC thickener; mc201 provides high shear viscosity, increases film fullness and improves construction splash resistance Lustrous coating: HEUR (such as pu-40) thickener has the highest lustre potential, while Newtonian hase (such as mc-201) thickener can catch up with HEUR in many formulations; Interior wall mercerizing paint: recommended T33 and PU40, T33 as acrylic thickeners, unique internal crosslinking characteristics to give the coating excellent construction performance, its yield value is high, it can prevent sedimentation, prevent coloring paint floating color and flower; PU40 for emulsion association ability, excellent canning effect, excellent construction performance, especially suitable for emulsion content higher system We use 2 ‰ mc201 and 7 ‰ MC35 (accounting for the total amount of coating) in the formula of interior wall emulsion paint, and 3 ‰ t33 and 3 ‰ pu40 (for the total amount of coating) in the formula of interior wall mercerization The viscosity is relatively balanced in low, medium and high shear viscosity After 48 hours, the viscosity tends to be stable Four Considering the gloss and permeability of the paint film, the emulsion content is generally controlled in the range of 15% to 40% of the total coating For the interior wall mercerizing formula, many paint factories love to choose the vinegar TERT emulsion The film prepared by the film is slightly higher than that prepared by styrene acrylic emulsion, but the price of vinegar tertiary emulsion is higher than that of styrene acrylic emulsion, and the water and alkali resistance are not better than that of styrene acrylic emulsion Therefore, we think that using vinegar emulsion is the best choice We use styrene acrylic emulsion TL-615 (18% of the total coating) in the latex paint formula of the interior wall, using the acrylic emulsion RS-998A (38% of the total coating) in the interior wall mercerizing formula, and the comprehensive performance is excellent 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,
