Acrylic Primer AP-300 is an acrylic emulsion copolymer with very fine particle sizes and good adhesion to many different substrates. It can penetrate into the substrates to form a strong network, provide high level of water resistance, improve the adhesion between old and new concretes, and help the workability for self-leveling concretes.

Acrylic Primer AP-300 has the following benefits:

1. Excellent water and abrasion resistance
2. Good adhesion to the substrates and excellent water repellency
3. Good workability
4. Environmental friendly
5. Suitable for any construction work

Typical Physical Properties
Appearance: Light translucent emulsion
Solids: 49.0 ±1.0%
pH: 8.0 ±1.0
Specific gravity: 1.06
Viscosity: 8,000 ± 3,000 cps (Brookfield, RVT, #6, 5 rpm)
Tg: 15℃

Method of Use
Remove all loose material and contaminates from substrate. Apply a thin uniform coating of Acrylic Primer AP-300  (diluted with 4X volumes of water) using either a spray or a brush. About thirty minutes later, apply the second coating of Acrylic Primer AP-300 (diluted with 2X volumes of water). Allow Primer to dry and make sure the ground is tack free (about 30 minutes), then apply self-leveling underlayment, concrete, elastic cement or any other construction works. The coverage of Acrylic Primer AP-300 will depend on surface porosity; usually 1Kg Acrylic Primer AP-300 can cover about 5 to 7 square meters.
