PRi CRETE
PRiBOND’S PRi CRETE is an acrylic emulsion which when added to cement mortar / concrete / grout provides good adhesion, water resistance and improvement of other properties. It is available in form of a milky liquid.
Acrylic Modified Emulsion & Waterproof Additive For Mortar & Concrete
STORAGE & SHELF LIFE
Storage
- Store under cover away from direct sunlight and protect from extreme temperature
- In hot temperature conditions, it must be stored in a temperature-controlled environment i.e., less than 30°C.
Shelf Life
- Shelf Life is 18 months from the date of manufacturing.
HEALTH AND SAFETY
- PRiBOND is alkaline and should not come into contact with skin or eyes.
- Avoid inhalation of dust during mixing.
- Gloves, goggles and dust masks should be worn.
- Any contact to eyes should be washed immediately with clean water and seek medical advice.
Packing
5KG & 20 KG
PRi CRETE is a high quality emulsion that substantially increases the quality of cement
mortars /concrete /grout for :
- Rendering and coating
- Jointing
- Repair and adhesive mortar
- Roof finishing
- Bonding of concrete casts
- Tiling
- Waterproof rendering
- Cement injection mix.
- Extremely good
- adhesion.
- Reduced shrinkage.
- Greater elasticity.
- Excellent oil and water resistance.
- Increased abrasion resistance.
- Improved chemical resistance.
- Improved UV resistance.
- Concrete surfaces should be sound and clean, free from oil, grease, cement laitance & loosely adhering particles.
- Absorbent surfaces should be saturated thoroughly with water but without showing any puddle on their surfaces.
Mixing :
Mixing of diluted PRi CRETE to cement mortar / concrete should preferably be done manually. When a concrete mixer is used,
pour the mortar as soon as its consistency is cohesive. Do not run the mixer too long.
Aggregates :
Aggregates used in the mortar / concrete
| Thickness of Mortar | Particle Size |
|---|---|
| 5 mm | 0 – 2 mm |
| 6 – 15 mm | 0 – 3 mm |
| over 15 mm | 0 – 5 mm |
1.Bond Coating:
Prepare the base as indicated above. Apply cement based primer by using PRiCRETE : Water = 1: 4 by volume in order to obtain
a thin layer. When the primer coat is still fresh and sticky apply mortar made out of PRi CRETE& water combination.
2. Masonry Jointing:
Prepare the base as indicated above. Make a firm mortar with fine sand & cement using PRiCRETE : Water = 1: 8. Impregnate
the area with primer coat as above. While the primer is wet, apply the mortar and immediately finish or reshape the surface as
required..
3.Waterproof Plaster :
Dilute PRi CRETE with water in the proportion of 1: 6 by volume. Prepare the mortar with this gaugingmortar. Cured Plaster with
PRi CRETE would harden faster and would be watertight.
4.Bonding Successive Concrete Casts :
Wash the surface with high-pressure jet. Prepare a pasty mortar with PRi CRETE: Water = 1: 8 by volume. Apply this mortar onto
the surface in a layer of 23 – 30 mm thickness. Pour fresh concrete after about an hour. Vibrate carefully to achieve satisfactory
interpenetration of mortar and concrete.
5.Polymer Modified Cement Grout for Injection :
Open the crack lines into V and U groove and fix galvanized iron nozzles spaced at regular intervals of 0.5 to 1.5 mm c/c along
groove length with PRi CRETE or PRI LATEX SBR. Prepare a cement grout slurry admixed with PRi CRETE at dilution rate of 1: 4 to
1: 8 by volume with water. Inject the fluid as per normal.
6.Cleaning of Tools :
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed
mechanically
7.Curing Treatment :
Ensure that freshly applied mortars, renders, floor toppings, etc, are adequately protected from the drying effect of wind, sun
and high temperatures. Adopt a curing regime appropriate to the application such as water mist, wet hessian, plastic sheeting,
curing membranes.
