MYMIX SBR 330
Product Description
MYMIX SBR 330 is a Styrene Butadiene Rubber Latex for improving adhesion strength of all types of cement based mortars with water and vapour resistant bonding properties.
Advantages:
- Excellent adhesion to cement based mortars
- Improve the Flexural and tensile strength
- Lower shrinkage characteristics
- Multipurpose and Economical
- Easy to use
Area of Application:
- Waterproofing and repairingstructures
- Surface treatment and protecting
- Excellent choice to use concrete, glass bricks and high porous substrates
- Can use as bond coat mixing with cement and sand
Shelf Life:
- Best before 12 months from the date of manufacturing, in unopened condition and stored in dry area.
- Avoid direct sun light.
Packing Details:
- Available in 200ml, 500ml, 1 Liter, 5 Liter, 20 Liter.
- Bigger packing sizes are available on request.
Surface Preparation:
- All concrete Substrates: All concrete surfaces should be clean from dust, free from contamination, efflorescence and curing compounds.
Method of Application
| Application | Mixing Properties | Application Tools | ||
|---|---|---|---|---|
| Cement in Kg | SBR 330 in LTR | Sand in Kg | ||
| As Bonding Agent | 1 | 1 | ----- | brush application |
| As Repair Mortar | 5 | 0.750 | 15 | trowel application |
| As Waterproofing | 1.5 | 1 | ------ | brush application |
Mixing For Old Concrete to New Concrete Substrate:
- Add MYMIX SBR 330 in a plastic container and take 1 kg of cement.
- Add cement gradually to MYMIX SBR 330 with constant mixing.
- Ensure that premix should be uniform slurry and without lumps.
- Apply slurry on the properly prepare substrate using paint brush.
- Leave for 24 hrs and allow it to cure.
For Mortars and Plaster
- Use 6 to 7 Liter of MYMIX SBR 330 per 50kg bag of cement to improve the properties of plaster mortar free from shrinkage crack and for higher compressive and tensile strength.
- Cured plaster with MYMIX SBR 330 would harden faster.
