• ASTM C494: Types A & D

12 months from date of production if stored in unopened, undamaged and original sealed packaging.

SikaPaver®-707 must be stored where temperatures do not drop below +5°C. If the product has frozen, thaw at +5°C or above and completely reconstitute using mild mechanical agitation. Do not use pressurized air for agitation. Store under cover, out of direct sunlight and protect from extremes of temperature.

SikaPaver®-707 is compatible with most admixtures used in the production of quality concrete including normal, other mid-range and high-range water-reducing admixtures, air entrainers, accelerators, retarders, extended setcontrol admixtures, corrosion inhibitors, and shrinkage reducers.
SikaPaver®-707 is also compatible with slag and pozzolans such as fly ash and silica fume.

As a guide, a dosage range of 200 ml to 400 ml per 100kg of cementitious material is recommended.
Optimum dosage of SikaPaver®-707 should be determined with trial mixes. Higher dosages may be required when certain combinations of materials and conditions are present or water reduction in excess of 15% is required. Because of variations in concrete materials, job site conditions, and/or applications, dosages outside of the recommended range may be required.

Points to remember when producing waterproof concrete:

• Ensure water/cement ratio is within the range of 0.40 to 0.60.
• Keep water content as low as possible.
• Place concrete quickly and compact it well.
• Ensure complete curing with a MASTERKURE curing compound.

Effects of Over Dosage
A severe over-dosage of MasterPel 707 shall result in some of the followings:

• Extension of the initial and final set
• Increase in air entrainment
• Bleed/segregation of mix, quick loss of workability
• Increased plastic shrinkage

A slight overdosing may not adversely affect the ultimate strength of the concrete and can achieve higher strengths than normal concrete, provided it is properly compacted and cured. Due allowance should be made for the effect of fluid concrete pressure on form work, and stripping times should be monitored.

SikaPaver®-707 is a ready-to-use liquid which is dispensed into the concrete together with the mixing water. The plasticising effect and water reduction are higher if the admixture is added to the damp concrete after 50 to 70% of the mixing water has been added. The addition of SikaPaver®-707 to dry aggregate or cement is not recommended.
