5 Things You Need To Know About Chalking
1. What are the approved wall plasters on the market?

Painters on the market today traditionally use raw materials such as vegetable glue, powder, gypsum powder, varnish and white glue to make batches of wall plaster by themselves, and the price and cost are relatively economical. But in fact, making batches of wall plaster by yourself requires certain skills, and the stability is not enough, so you still buy ready-made batches of wall plaster for construction. Nippon Paint Odour-less Wall Putty was launched with high quality considering the difficulties encountered in chalking, such as technique, effect, smell and so on.

2. What are the problems with vegetable gum powder in the market?

In fact, the vegetable glue powder on the market requires a lot of effort to prepare, and the most important thing is that the use of vegetable glue powder can easily cause mold on the wall! Because vegetable gum is a plant fiber, extracted from seaweed, it is easy to cause bacteria to grow on the wall.

3. How to perfect chalking?

Chalking can be divided into three steps:
1. Clean up the dust
2. Chalking
3. Polish
Clean up the dust is actually to fill up some uneven walls with large gaps to make them smooth, and add plaster to increase their stability. The next step is to apply the dust to make the surface of the wall smoother and smoother, and achieve a smooth effect through repeated chalking actions. However, the chalking should not be too hasty to apply all at once. It is necessary to wait for each layer of the dust to dry before applying the dust again. Otherwise, cracks will appear on the wall, and if you apply too much too quickly, the natural absorption will be uneven, so remember not to be too quick and too thick at once. The last step is to polish, which is mainly to sweep away the excess dust on the wall and make the overall wall smoother and smoother. The polish also needs to be repeated many times to make the paint more full and smooth. As for the polish tool, you can choose Nippon Bang Sanding Sponge, which uses high-density sponge, electrostatic sand planting process, parallelogram design, easy to polish the corners, good elasticity, durability, not easy to remove sand, and can be reused after cleaning.

4. What you need to know about special weather?

The wall has been severely eroded by the accumulation of precipitation over time. In addition to the problem of time, there are also reasons for the climate. Because the climate in Hong Kong is often humid, and the housing environment and structural problems in Hong Kong are quite special, the sunlight cannot fully shine into the house, which makes the problem of humidity in the house gradually serious. In addition to re-cleaning the dust, the best way is to take good ventilation measures, for example: opening the windows to allow air convection, which can effectively eliminate the humid molecules mixed in the air. Or some special weather, such as the weather after rain or the rainy season that is prone to mold, you need to pay attention when these weathers occur. Residents with dehumidifiers can use dehumidifiers to strengthen the elimination of moisture in the house. Content, fully keep the room in a state of constant temperature, dryness and humidity.

5. How to deal with special circumstances

Residents may encounter some serious wall problems. For example, the wall has been aged for more than 10 years, and a large area of the wall has been severely affected by moisture. Carry out a major renovation, and redo it together with the paint and dust on the wall. You don't have to worry about this cumbersome project, because Nippon Paint has launched a refresh service for homeowners who need major renovations to help them solve the problem. All the problems encountered in the renovation do not need to be done by the customer at all. Nippon Paint provides one-stop service, and also provides a variety of renovation cases for customers to refer to, so that everyone can have a general understanding of the renovation, and then a series of renovations will be introduced Process, answer customers' doubts, strive to achieve excellence, and provide residents with a perfect and comfortable living environment.

Paint Problem Solving And Advice

According to Porter's Paints: paint problem solver & advice

generate bubbles
Air bubbles are created in the paint film, resulting in a localized loss of adhesion.
possible reason
– Substrate humidity is too high
– Paint on soiled or decayed substrates
– Paint on overheated substrates or expose to direct sunlight
– poor working or drying conditions (e.g. high humidity, condensation, rain)
– Identify the cause and extent of the problem. Resolve the cause, strip off the old paint, make sure the substrate is properly repainted. (Some substrates are too damaged to be repaired, such due to replacement)

The surfaces of two freshly painted objects are glued together (eg a window is glued to a frame).
possible reason
– Close doors and windows before paint dries.
– poor working or drying conditions (e.g. low temperature, high humidity, condensation, rain)
– Sand to remove affected area, repaint after ensuring proper substrate.
– Provide correct drying time according to paint label recommendations.
– Make sure the workmanship and drying conditions are in accordance with the manufacturer's recommendations.

Oil sweep/oil reel marks
Unintentional texture left in paint by an oil sweep or reel.
possible reason
– Painted with low quality/incorrect tools.
– Poor workmanship (eg too fast or too much paint).
– Repaint or reroll partially dried paint.
– poor working or drying conditions (e.g. overheated substrate, high temperature)
– Lightly sand affected area until smooth, repaint
– Use consistent painting techniques (such as applying oil reel pressure evenly from top to bottom) while keeping the edges wet.
– Make sure to use high quality and recommended tools and equipment.
– Make sure the workmanship and drying conditions are in accordance with the manufacturer's recommendations.
– In hot or windy conditions, the recommended amount of thinner can be added to improve workmanship.

Powder on the surface of the paint film, produced by the degradation of the paint binder.
possible reason
– Use interior grade paint on surfaces exposed to UV radiation.
– Surfaces where the painted surface has been fully exposed to strong sunlight for a prolonged period of time, and/or has an elevated salt concentration (eg coastal areas).
– Use dark paint, which absorbs more heat and UV rays from sunlight than lighter colors.
– Paint lighter than recommended thickness.
– Wash the affected area, remove all surface contamination and powder, and repaint with a UV–resistant paint system.
– Make sure to paint to the recommended coverage.
– To minimise chalking, have a maintenance schedule in place from the outset to ensure that painted surfaces are cleaned and repainted within scheduled times.

The salt migrates to the surface of the porous masonry substrate, forming a white scabbed deposit.
possible reason
– Excessive moisture in the substrate
– Paint on under–cured substrates.
– Use a stiff brush to remove deposits, then clean the surface with a mild white vinegar solution (acetic acid). In severe cases, a stronger acid solution should be used by an experienced contractor to remove mineral salts and then allowed to dry.
– Identify and eliminate the source of moisture and repaint once the surface is intact, clean, dry and free of mold and algae. Alkali–resistant sealants and a suitable topcoat are recommended.

Excessive tarnishing of the paint coat.
possible reason
– Use interior grade paint on surfaces exposed to UV radiation.
– The painted surface is exposed to high salinity (e.g. coastal areas).
– Colors such as bright blue, yellow, red are particularly susceptible to UV radiation.
– Add a colorant higher than the recommended coloring level.
– The paint film used is lower than the recommended thickness.
– Thoroughly clean the affected area, remove all surface contamination and repaint.
– Use manufacturer–approved UV–resistant paint products and coating systems.
– Make sure to paint to the recommended coverage.
– To minimise fading, have a maintenance schedule in place from the outset to ensure that the painted surfaces are cleaned and repainted within the scheduled time.

Air bubbles formed during application and pits created when air bubbles burst in the paint film.
possible reason
– Painting with improper tools (eg oil reel fuzz length, material type).
– Poor workmanship (eg too fast or too much paint).
– Over–mix the product before use.
– Paint with old and/or improperly stored paint.
– Make sure to use the correct application equipment and technology. If you notice excessive foaming in the can, allow the paint to settle before using.
– Correct foam in dry paint film, lightly sand affected area to a smooth surface and repaint. In some instances, lather in the wet film can be corrected by light application with a brush.

wear and tear
When the painted surface is worn or impacted, visible shiny spots or areas of polishing can appear.
possible reason
– Use low–gloss, matte and flat paint in heavy tones (dark or vivid), especially in high–traffic areas
– Fang.
– Frequent cleaning and/or spot cleaning, especially with abrasive cleaners or tools (wire balls).
– Unintentional bumps on painted surfaces (eg furniture rubbing coatings).
– Critical or low angle lighting may accentuate any worn look that has a chance.
– Repaint with higher gloss or lighter color paint.
– In some instances, a durable clear coat may be recommended.

Black, grey, brown spots on the painted surface.
possible reason
– Presence of moisture (condensation in the substrate, surface or high humidity).
– Paint on moldy substrates.
*TIP: Test for mold by putting a few drops of household bleach on the discolored area; if it disappears, it's likely mold.
– To get rid of mold, scrub the surface with a diluted household bleach solution (one part bleach, three parts water) while wearing rubber gloves and goggles. Rinse thoroughly.
– To prevent mold, use paint with anti–mold properties.

Deep, irregular cracks in the dry paint film.
possible reason
– Applying too much paint causes the surface of the paint film to dry faster than the rest (most commonly where paint can overlap, such as corners).
– Poor working or drying conditions (e.g. too cold substrate, too low temperature).
– Sand the surface flat and repaint at the recommended coverage.
– In some instances, oil–based primers or high–concentration products may be required.
– Ensure application and drying conditions comply with manufacturer's recommendations

Rusty nail head
Red/brown rust on painted surfaces.
possible reason
– Paint on ungalvanized iron nails, which tend to rust in wet environments.
– Paint on galvanized nail heads that have started to rust from sanding or excessive weathering.
– Wash off rust, sand nail heads, and follow new construction finishing procedures.
– When painting new exterior construction, if non–galvanized nails are used, it is advisable to countersink the nail head first and then caulk with a good quality exterior acrylic caulk.
– Each nail head area should be topically primed (preferably with an antifouling primer) followed by a good quality topcoat.

Poor gloss or color uniformity, especially when looking flat from an angle.
possible reason
– Paint on surfaces with different textures and uneven porosity (joints between plasterboards).
– Failure to properly prime the substrate.
– Inconsistent workmanship
– Bad working or drying conditions (eg high temperature, high temperature).
– Before applying the topcoat, the new substrate should be treated to ensure uniform porosity of the substrate.
– Use consistent painting techniques (such as applying oil reel pressure evenly from top to bottom) while keeping the edges wet.
– Make sure the workmanship and drying conditions are in accordance with the manufacturer's recommendations.

Cracking and peeling
The paint film forms a definite fracture, the local adhesion between the paint film and the substrate is lost, or the paint film is completely separated from the surface substrate.
possible reason
– Paint on unsound substrates (e.g. weathered wood, weak concrete or plaster)
– Paint on soiled or loose materials.
– Paint on overly smooth surfaces that are difficult to bond.
– No precoat (primer) used, poor quality or the wrong type for the substrate.
– Lack of maintenance of existing paint
– Before starting any new paint, the extent and cause of the problem needs to be clearly identified, the cause removed, and the old paint stripped until the substrate is sound.

A matter of appearance, areas where you paint with an oil brush look brighter or darker than areas where you use an oil reel.
possible reason
– Apply wet paint on dry or semi–dry areas
– Differences in gloss and/or surface texture due to different workmanship between oil brushes and oil reels.

5 Reasons Why Stucco Painting is a Good Idea

Seals Out MoistureStucco with water on it
You might see that after it rains, your stucco absorbs some of the water and becomes darker until it dries. When you apply a new coating of paint, this will seal the moisture out. This will allow you to waterproof your exterior and keep dampness at bay. Paint makes your home weather resistant and provides an extra layer of protection between your family and outside. Keeping water out will keep your stucco beautiful for years to come.

1.Covers Stains
A variety of stains can appear on your stucco over the years. Rust is particularly prevalent from window frames where nail heads could be oxidizing and running stains down the stucco. Some homeowners find their sprinklers leave orange colored stains on the house as well. All of these stains can easily be covered with a coating of primer and new paint.

2.Fills Hairline Crackscracked stucco
Hairline cracks can turn into a much more expensive repair if they are not addressed. When left alone, chunks of stucco can crack and fall off turning a small problem into a large one. Painting your stucco home will fill in these small cracks and make your home look pristine again.

3.Larger cracks could need to be repaired. 
Professional painters will be able to use exterior caulk or masonry to patch the issue areas. It’s important to take care of problems when you find them. Before a paint job is the perfect time to make repairs, since the paint will match perfectly once the job is complete.

4.Better Curb Appeal

Whether you are getting ready to paint your house or just looking to refresh it, painting the exterior can make a massive improvement. The right color will impress visitors, potential buyers and neighbors with a crisp and clean looking home.

5.Resists UV Rays
During the summer months, the UV rays can wear away at the durability of your paint. The paint is the first line of defense between your family and the outside weather and pests. This can lead to cracks and holes in the masonry. If left unattended, it can ultimately lead to structural damage. Painting the stucco with regularity, you’ll protect your home from UV rays and precipitation.
