When used as pump primer, Primetech eliminates the need for premium priced grout slurries or bagged cement primers. As a pumping aid, Primetech enables the pumping of harsh, lean or over-watered mixes, reduces line pressure and increases the range of pumpability.
For Pump Priming: Use one 5 oz. (142 g) bag in 5 gals (19 l) of water to prime 100ft. of 5-in pump line. Remove the outer bag and add the water-soluble bag of Primetech to 5 gals. of water. Mix for one minute, then allow the mixture to set for at least 5 minutes. For concrete mixes with superplasticizers, increase mix water content by 5 gallons (19 l) to reduce line blockages. Pour into the priming port or hopper just prior to pumping. In some cases, priming directly in the hopper may be possible.
