Takeaways
- 🎨 The main topic of the video is about common issues encountered during and after wall painting and how to solve them.
- 🧪 Painting high-quality paint over low-quality paint can lead to stains because low-quality paint dissolves easily in water, causing streaks.
- 💧 Moisture from outside the wall can also cause paint to peel or stain, especially when cheaper paints are used.
- 🌦️ Low-quality exterior paints are unable to withstand extreme weather, leading to peeling or cracking after being exposed to rain or heat.
- 🔧 When high-quality paint is applied over low-quality paint, the weak foundation can cause the top layer to peel away.
- 🔨 If painting over high-quality paint, sanding the surface first helps the new layer adhere properly, especially for exterior use.
- 👷 For exterior walls, using specialized exterior paint is recommended to prevent issues like peeling and cracking.
- 💪 Good-quality interior paint, when applied over damaged surfaces, can last longer if applied properly with appropriate primers or repairs beforehand.
- 💡 It is advised to match the paint brand and type when applying new layers to avoid chemical incompatibilities that can lead to damage.
- 🏠 New walls or freshly plastered surfaces should be fully cured and primed before painting to prevent stains or peeling.
Q & A
What causes stains to appear after painting walls with good paint over bad paint?
-Stains appear because the bad paint underneath is weak and easily dissolves when exposed to water. This allows dirt and debris trapped during the painting process to surface, resulting in stains.
Why does bad paint dissolve more easily when exposed to water?
-Bad paint often contains chalk-like substances that are more prone to melting and mixing with water, making it easier for dirt and stains to form.
What happens when good paint is applied over bad paint on exterior walls?
-Good paint may not hold well on exterior walls if bad paint is underneath, as exposure to weather conditions like rain and heat can cause the bad paint to crack and peel, affecting the overall durability.
How can moisture cause stains or crusting on walls?
-Moisture can seep into walls with poor-quality paint, leading to the formation of crusts or stains as the paint becomes eroded and the debris separates from the surface.
What is the recommended solution when bad paint is found underneath a good layer of paint?
-The best solution is to sand the surface before applying new paint, especially if it’s exterior. This removes the weak layers and allows the new paint to adhere properly.
Why is it risky to apply cheap paint over good-quality paint?
-Applying cheap paint over good-quality paint can result in poor adhesion because good-quality paint doesn’t absorb water well. The cheap paint can peel off easily and affect the finish.
What is the ideal time to paint a newly plastered wall?
-It is ideal to wait at least three months after plastering a wall before painting to ensure it is completely dry. Applying paint too soon can lead to stains and streaks.
What should be done if stains appear on newly painted walls?
-If stains appear, you should use the same brand and type of paint to cover them. This helps avoid chemical mismatches that could lead to further problems.
Is it better to use exterior-specific paint on outdoor walls, even if it’s more expensive?
-Yes, it’s recommended to use exterior-specific paint as it is designed to withstand harsh weather conditions like rain and sunlight, preventing peeling and damage over time.
What is a potential problem with mixing paints from different manufacturers or with different chemical compositions?
-Mixing paints from different manufacturers or with different compositions can lead to chemical reactions that cause peeling, stains, or poor adhesion, resulting in an uneven or damaged finish.
Outlines
🎨 Common Issues When Painting Walls
The video begins by discussing common problems that arise during and after painting walls. It emphasizes the need to understand the root causes and solutions to prevent issues like stains and marks from occurring. The speaker starts by addressing what happens when a good quality paint is applied over a poor quality one. Poor quality paint tends to dissolve when it comes into contact with water, causing stains to reappear on the surface, even after being painted over. This happens because the impurities from the original paint mix with the water and migrate, leading to visible marks and stains. The solution is to use a higher-quality paint from the start, or apply a primer to avoid these issues.
🔄 Effects of Painting Poor Quality Paint Over Good Quality Paint
In the second paragraph, the speaker explains what happens when poor quality paint is applied over good quality paint. Due to exposure to outdoor conditions like rain and sun, poor quality paint is unable to adhere properly and eventually peels off. This is because good quality paint doesn’t easily absorb moisture, making it a poor foundation for low-quality paint. The speaker advises viewers to always consider the quality of the paint before applying it over an existing layer. For outdoor surfaces, it is crucial to use paint specifically designed for exterior use, as it can withstand harsh weather conditions.
🏠 Painting Good Quality Paint Over Good Quality Paint
This paragraph discusses applying good quality paint over another good quality layer. Even though both paints are of high quality, they might not bond well together. This is especially true for exterior surfaces exposed to weather changes. The key takeaway is that the new layer might not adhere well unless the surface is sanded or primed beforehand. The speaker advises sanding the surface lightly before applying a new layer to ensure better adhesion and a longer-lasting finish.
⚠️ Potential Issues with Painting Good Quality Paint Over Poor Quality Paint
Here, the speaker describes how applying a good quality paint over poor quality paint can lead to unsatisfactory results. Because the original layer of poor-quality paint doesn’t absorb moisture well, the new paint layer may not stick properly and might start peeling. To avoid this, it’s recommended to sand down the original layer or use a primer to improve adhesion. The paragraph also mentions that mixing different brands or types of paint can result in chemical incompatibility, causing stains or peeling.
🛠️ Challenges with Painting New Walls
The fifth paragraph focuses on the challenges of painting newly plastered or ‘virgin’ walls. It’s advised to wait at least three months after plastering before applying a primer. Painting too soon can result in marks and stains, as the moisture from the plaster hasn’t fully evaporated yet. For those who have already painted too early and encountered issues, the solution is to apply the same brand of paint again after ensuring the wall is fully dry. Proper preparation and timing are crucial for new walls to achieve a flawless finish.
💡 Final Recommendations for Successful Wall Painting
The speaker concludes by reiterating the importance of using similar quality paints for best results. Applying low-quality paint over high-quality paint or vice-versa can lead to peeling, stains, and other issues due to chemical incompatibilities. When choosing paint for exterior surfaces, it’s recommended to invest in paints designed for outdoor use, as they are more resistant to weather changes. The video ends with a positive note, wishing viewers health and success, and encourages using the right materials and techniques for a lasting, professional-looking finish.

Highlights
The problem of applying good paint over bad paint often leads to stains because bad paint is more prone to dissolving in water and bringing dirt along.
Bad quality paint tends to melt when exposed to water, causing dirt to collect and form stains after drying.
Dirt accumulates due to trapped particles from the previous paint layer, which are released when exposed to water.
The problem may also arise from external moisture, such as dampness, which can exacerbate paint degradation.
The solution to bad paint covered by good paint is often sanding the old paint before reapplying a better-quality layer.
Applying bad paint over good paint causes peeling and cracking, especially in outdoor conditions where heat and rain weaken the poor-quality paint.
Even if bad paint is applied over a good base, the weaker layer cannot withstand the weather, leading to flaking and cracking.
Specialized exterior paints are available that can better resist heat, rain, and cracking, reducing these problems.
Good quality paint on a good foundation, even after multiple years, doesn't develop stains or cracks as much.
Interior paints, when applied in the right conditions, tend to last longer without showing defects even after several months.
A common issue with new walls is staining or residue due to incomplete drying of the plaster layer underneath the paint.
Walls that have been plastered need to dry for up to three months before applying a primer and then the final paint layer.
Different paint brands and chemical compositions can lead to problems like stains or poor adhesion if mixed without proper preparation.
Applying inexpensive paint over inexpensive paint can still yield good results if done correctly, with attention to compatibility.
For exterior walls, using a specific exterior-grade paint ensures better protection against the elements and longer-lasting results.

salam kreatif teman-teman kali ini kita
akan bahas
masalah-masalah yang sering muncul saat
ngecat tembok atau setelah ngecat tembok
ya teman-teman diantaranya yang kayak
gini nih makanya supaya nggak terjadi
hal seperti ini lagi kita perlu tahu apa
penyebabnya dan Apa solusinya bukan cuma
masalah noda-noda kayak gini
masalah-masalah lain pun yang umum
terjadi akan kita bahas Tuntas di sini
teman-teman
yang pertama saya mau sharing di sini
cat bagus di Tiban cat jelek nah ini
untuk Titan dibanding ban cat ya
teman-teman kalau cat bagus di Tiban cat
jelek muncul noda-noda kayak gini wajar
teman-teman Kenapa karena chat bagus itu
biasanya dia berdiri sendiri ya dan
jelek itu biasanya dia rentan banget
rentan banget maksudnya apa dia kalau
terkena air teman-teman maka zat
kapurnya itu gampang banget meleleh atau
gampang banget ngikut dengan aliran air
jadi ngikut dengan aliran air ngebawa
kotoran-kotoran yang waktu kita ngecat
dengan kuas atau dengan roll karena
otomatis itu ada kotoran atau ada debu
yang nyangkut dan akan buyar lagi saat
kena air teman-teman jadi dia akan
memisahkan diri minggir-minggir-minggir
sampai pojokan air nah di situlah
kotoran terbentuk lagi saat kering dan
membentuk noda kerak seperti ini saya
akan buktiin di sini saya akan ambil
sedikit air dan saya akan berkelahi
temboknya ya cat temboknya akan saya
cipratin saya akan basahi di sini
teman-teman bisa lihat dia udah otomatis
apa langsung ilang ya langsung ke bawah
air dan muncul lah cat lamanya yang
bagus seperti saya bilang tadi cat
lamanya itu seperti berdiri sendiri cat
yang jelek itu atau yang kurang bagus ya
yang biasanya harganya murah-murah
banget itu ya dia akan melebur atau
membaur membuyar ya Maksud saya dia akan
membuyar begitu aja ikut dengan aliran
air dan kotoran-kotoran yang di bawah
dari bekas cat itu akan Membekas dan
itulah terjadinya kerak bisa juga ini
karena lembab ya lembab dari luar bisa
juga mengakibatkan dinding berkerak atau
bernoda seperti ini metodenya sama
mirip-mirip karena murah tadi dia
gampang terbawa air atau tergerus air
sehingga kotorannya yang memisahkan diri
ke pinggir-pinggiran Terus solusinya
gimana sambil jalan kita bahas
teman-teman lanjut
yang kedua yaitu cat jelek di Tiban cat
bagus gimana hasilnya kalau di eksterior
teman-teman kayak gini teman-teman
kepanasan kehujanan timbulnya kayak gini
cat jeleknya nggak akan mampu untuk
menopang cat bagus teman-teman Ya
namanya juga cat kurang bagus dia akan
mudah terbawa air kayak tadi akhirnya
Kalau saat hujan atau saat panas dia ada
retak-retak semuanya jadi ngelupas
seperti ini Nah kalau misalkan cat
luarnya itu jelek kayak tadi tentunya
udah terkikis air ya teman-teman karena
cat luarnya ini bagus dia nih ban cat
lama yang jelek akhirnya dia pondasinya
dicat lama cat lama nggak kuat menopang
panas dan air makanya dia nyoplok semua
kayak gini ini contoh cat umum ya yang
saya pakai teman-teman yang cat interior
yang saya pakai biasanya zaman sekarang
ini udah banyak cacat khusus eksterior
untuk menghindari hal-hal seperti ini
teman-teman karena sebagus-bagusnya cat
interior kalau dipakai di luar dia
kepanasan kehujanan lama-lama kasusnya
akan seperti ini juga Tapi kalau nggak
kepanasan nggak kehujanan dia sebenarnya
aman-aman aja teman-teman
ngomong-ngomong sembari lewat ini kusen
saya yang keropos dulu ya teman-teman
udah 2 tahun lebih ya masih bagus kita
akan cek chat jelek di Tiban cat bagus
yang enggak kepanasan enggak kehujanan
Contohnya kayak gini teman-teman udah 4
bulan dia masih bagus ya Ini terakhir
kali saya dempul ya untuk retakan atau
pecahan di dinding ini gede banget
teman-teman dan sekarang ini masih mulus
banget tanpa ada retakan baru yang
muncul ini udah 4 bulan banyak juga yang
nanya ini sekarang kabarnya Gimana Bang
retak lagi apa enggak Nah ini nih
teman-teman teman-teman bisa lihat
sendiri lah retakannya enggak muncul
lagi Insyaallah ini selamanya kalau
enggak ada gempa nih ini enggak akan
muncul Letakkan lagi teman-teman
catnya juga kuat banget aman banget nah
step-stepnya ada di video itu tuh
teman-teman waktu benerin ratakan ini
ini cat interior yang saya pakai di
eksterior sebenarnya kalau ada dana
belilah cat eksterior khusus ya yang
anti hujan anti panas teman-teman untuk
lebih amannya
yang ketiga cat bagus di Tiban cat bagus
bagus di sini yang saya maksud di
kisaran harga kurang lebih 200ribuan ya
teman-teman nggak yang mahal banget 500
sampai sejutaan kalau yang mahal
sekalian kayak gitu jangan ditiban-tiban
kayak begini atau jangan nibani kayak
begini Nah kalau yang bagus ketemu bagus
kayak gini teman-teman untuk di luar
enggak cocok karena dia kepanasan dan
kehujanan akhirnya bagian luarnya itu
akan memisahkan diri karena dia
masing-masing berdiri sendiri dan
masing-masing nempel sendiri-sendiri
yang mana yang paling kuat erat
nempelnya dia yang bertahan nah ini
nempel di atas cat bagus otomatis dia
itu terbagus tuh agak licin enggak mudah
terbawa air saat ngecat ini airnya tuh
enggak benar-benar nyerap di cat
bagusnya akhirnya ya kayak gini kalau
untuk di luar kalian kali kalau untuk di
luar mau di Tiban itu minimal di Amplas
dulu lah ya teman-teman jangan langsung
Tiban
yang keempat pertimbangkan untuk niban
cat bagus dengan cat jelek kalau cat
bagus di Tiban cat jelek atau cat yang
lebih murah atau rendah kualitasnya itu
bakal kayak gini teman-teman dia nggak
akan merekat kuat di cat bagus karena
cat bagus itu enggak menyerap air atau
kurang menyerap airnya sehingga dia
bagus ya nggak mudah luntur nah tapi
kalau cat bagusnya ini kita amplas dulu
dan kita Tiban dan jelek itu sayang
banget teman-teman ya Selain Nanti kalau
dia itu bisa berjamur dia bisa bernoda
akhirnya yang bagus jadi ikutan jelek
masalah yang kelima tembok rumah perawan
yang baru dicat itu biasanya akan
menimbulkan noda atau kerak kayak gini
itu kenapa itu karena aciannya itu atau
plesterannya itu belum Lama banget
teman-teman jadi belum kering sempurna
Oleh karena itu biasanya lebih bagus
kalau tembok itu di plamir setelah Acian
itu berusia 3 bulan Nah setelah masa
dari plamir itu setelah 3 hari kemudian
di plamir baru naik cat teman-teman
enggak bisa sebulan habis di aci terus
kita plamir terus kita cat itu maka akan
berbayang dia akan muncul noda seperti
kerak atau seperti noda-noda peta buta
nah solusinya buat yang udah terlanjur
kayak gitu beli cat yang sama dengan
merk yang sama Tiban lagi catnya
teman-teman itu bisa
terus intinya dari semua masalah-masalah
ini seperti apa Nah untuk cat tembok
dengan kualitas atau harga yang rendah
itu kalau kita mau Tiban kita Tiban juga
dengan cat yang kualitas dan harga yang
rendah pula karena kalau dia jomplang
atau beda merk beda pabrikan dia akan
beda zat kimia dan akan mengakibatkan
masalah-masalah tadi makanya di video
ini saya praktekin untuk Nih Ban cat
yang aman dan yang murah meriah tapi
hasilnya itu bagus ya teman-teman karena
apa Karena kalau misalkan jomplang beda
pabrikan beda kualitas beda zat kimia
dia akan berakibat hal-hal yang seperti
tadi ini contoh untuk cat murah di Tiban
cat murah masih aman kalau caranya bener
ya teman-teman Nah kalau misalkan cat
bagus di Tiban cat bagus Nah kayak gini
hasilnya walaupun udah bertahun-tahun
dia enggak akan bernoda dia nggak akan
nyoplok dia nggak akan bergerak ya
enggak akan retak teman-teman nah ini
contoh satu lagi ya teman-teman untuk
cat bagus interior di Tiban dengan cat
yang bagus minimal kalau ada kerusakan
Dia paling kayak begini dia akan
bocor-bocel bocel berdiri sendiri
teman-teman enggak ngajak-ngajak di
sebelahnya atau enggak ngajak-ngajak
bagian yang lain Nah jadi Itulah kenapa
di video Sebelumnya saya wanti-wanti
bener kalau yang mau nibani ban cat itu
perlu diperhatikan chat sebelumnya
jenisnya Seperti apa Harganya berapa
gitu ya Mereknya apa usahakan yang
sepabrikan ya kalau mau lebih amannya
Nah kalau untuk eksterior untuk lebih
amannya biar enggak ngecat-ngechat
teman-teman bisa lakukan ini atau beli
cat khusus eksterior semoga bermanfaat
buat teman-teman subscriber dan juga
buat yang baru mampir Saya doakan
semuanya Semoga selalu sehat banyak
rezeki makin kreatif dan diberkahi
kesuksesan amin
