KDK exterior coating

Product No. KDK-20003

1.Introduction
    KDK exterior coating uses a unique water-repellency  and water-vapor permeability formula to make the wall breathable and water-repellent. The product allows the wall to withstand water, moisture and external rain, and protects the wall from peeling and loosening. At the same time, the water-based synthetic resin emulsion exterior wall coating is environmentally friendly. KDK coating film has the following features:

   

(1)	Good weatherability, up to 15 years.
(2)	Hard coating film, reduce surface contamination.
(3)	Breathable membrane, prevents moisture condensation.
(4)	Low water absorption can protect the wall from freezing and thawing (the high water absorption rate of ordinary coatings will cause pressure on the coating film when it expands due to freezing).
(5)	Keep the wall dry and prevent the growth of bacteria.
(6)	Environmentally friendly coating.
(7)	Flame resistance.
(8)	Recoatability. If you want to change the color of the exterior wall, you can easily coat the traditional coatings or KDK coatings in other colors on the original KDK coating. There is no adhesion problem.

3.Surface treatment
The surface to be painted must be completely free of grease, dust and loose materials. • Newly built walls should be completely dry. The moisture content of the surface of wall (or putty) must be less than 20%.

New wall:

(1)	The newly built concrete wall must be dried for 30 days before the putty can be applied.
(2)	The putty should not be too soft. After the putty is dried out, use fine sandpaper to rub down and remove dust.

Old wall:

(1)	When repainting the old wall that has been painted, use a blade and sandpaper to remove the dust and loose materials as well as loose paint film.
(2)	Use suitable putty to fill wall defects.

Moldy wall:

(1)	Use a blade and sandpaper to grind and remove the mold.
(2)	Brush with appropriate mold-proof water and rinse with clean water, wait until the wall is completely dried.

Appearance of alkalization:

(1)	Massively remove floating particles to reduce salt content.
(2)	Use special primer for KDK coating.

6.Use recommendations

(1)	Please read the instructions before use.
(2)	After opening the can, please stir the coating in the can before use.
(3)	Add appropriate amount of water according to the actual construction conditions, but do not over-dilute.
(4)	Avoid excessive coating on the brush or roller during construction.
(5)	Do not return the diluted coating to its original packaging.
(6)	Please use as soon as possible after opening the can.

7.Construction recommendations:

(1)	Primer	:	KDK coatings do not require a primer in principle, but in the case of old wall surface, surface containing a high level of water vapor, or a wall less than 1 meter from the ground, it is recommended to use the special primer for KDK coatings before spraying the KDK coating.
(2)	Theoretical painting area	:	In theory, 1 liter of product can cover 10 square meters, but the actual painting area will vary depending on the construction method and surface roughness.
(3)	Construction tools	:	Paint brush or roller, ordinary spray and airless spray.
(4)	Dilution method Paint brush or roller Ordinary spray Airless spray	: : : :	Depending on the ease of construction and temperature, up to 20% water can be added for dilution. Usually add up to 1 portion of water to 10 portions of paint, which is 10%. Usually add up to 1 portion of water to 5 portions of paint, which is 20%. It is generally not recommended to add water.
(5)	Spray recommendations Ordinary spray Airless spray	: :	most facilities can achieve satisfactory results Typical airless spray facility shall be set to a minimum working pressure of 140 kg per square centimeter (2000 pounds per square inch); Nozzle size 0.58 mm, nozzle angle 65 degrees.
(6)	Cleaning	:	Please wash with clean water immediately after use.

8.Miscellaneous:

(1)	Paint cans must be tightly fastened and placed out of reach of children.
(2)	Wear appropriate mask for protection when sanding the wall.
(3)	Maintain good environmental ventilation during use and drying.
(4)	Wear appropriate breathing equipment if the spraying construction is under insufficient ventilation. All breathing equipment must meet the approved standards.
(5)	Please place the product away from food and beverages

(6)	Wear protective glasses when using the paint.
(7)	If the product accidentally splashes into eyes, rinse immediately with plenty of water and go to the hospital for medical treatment.
(8)	If the paint is splashed on the skin, remove the paint first and wash the skin with soap or suitable detergent and water.
(9)	Be especially careful when transporting paint. Be careful not to trip or place upside down
(10)	When the paint is overturned, it should be covered with sand or soil and then cleaned up.
(11)	Never pour paint onto sewers or drains. Dispose of paint waste in accordance with local environmental standards.
