Kebanyakan rumah di Shah Alam 2 ini talah pun sedia di cat ketika di beli.Walaubagaimana pun ramai juga yang mengecat semula rumah mereka samada di bahagian dalam atau di bahagian luar, kerana mungkin mereka mempunya citarasa yang berlainan..
Semua orang tahu bagaimana mengecat, tapi takukah kita bagaimana mengecat dengan betul?.. Tahukah kita apa itu cat?.. Kenapa seringkali hasil yang kita dapati tidak seperti yang kita kehendaki setelah berhabis duit membeli cat?.. Cat yang bagaimana yang lebih bagus?.Apakah jenis jenis cat?...Yang murah atau yang mahal?..
Semua pertanyaan tersebut saya akan cuba huraikan satu persatu secara ringkas dan mudah di fahami..Sebelum itu sila lihat dahulu Technical Data sejenis cat yang di gunakan untuk primer atau undercoat.. mungkin ini akan mengubah persepsi anda terhadap CAT..

The substrate must be sound, clean, dry, free from dust, oil, grease and laitance etc. All traces of release agents must be removed. On chalky and dusty surfaces, all loose material must be removed by stiff bristle brushing.
The coating may be used on other substrates. Please contact your local Jotun office for more information.
Condition during application
Apply at a temperature between 10°C and 35°C.The temperature of the substrate should be minimum 3°C above the dew point of the air. The temperature and the relative humidity should be measured in the vicinity of the substrate.
Spray Use airless spray or conventional spray
Mixing ratio (volume) The paint is ready to use after proper stirring. If thinning is required, water may be added up to a maximum of 5%.
Guiding data airless spray
Pressure at nozzle 140 - 190 kg/cm² (2100 psi)
Nozzle tip 0.021" - 0.027"
Spray angle 65° - 80°
Filter Check to ensure that filters are clean.
Drying times are generally related to air circulation, temperature, film thickness and number of coats, and will be affected correspondingly. The figures given in the table are typical with:
* Good ventilation (Outdoor exposure or free circulation of air)
* Typical film thickness
* One coat on top of inert substrate
* Relative humidity 70%
Substrate temperature 10°C 23°C 40°C
Surface dry 2 h 1 h 0.5 h
Through dry 8 h 6 h 4 h
Dry to recoat, minimum 1 4 h 2 h 1 h
Dry to recoat, maximum 2,3
1. Recommended data given for recoating with the same generic type of paint.
2. In case of multi-coat application, drying times will be influenced by the number and sequence and by the total thickness of previous coats applied – reference is made to the corresponding system data sheet.
3. The surface should be dry and free from any contamination prior to application of the subsequent coat.
The given data must be considered as guidelines only. The actual drying time/times before recoating may be shorter or longer, depending on film thickness, ventilation, humidity, underlying paint system, requirement for early handling and mechanical strength etc. A complete system can be described on a system sheet, where all parameters and special conditions could be included.
Typical paint system
Jotasealer 07 1 coat
Jotashield 2 coats
Jotasealer 07 1 coat
Majestic or Strax 2 coats
Other systems may be specified, depending on area of use
