    Hi, was looking into buy a unit from star seal but was turned off when i started figuring out the shipping and what it would take to get it across the border into canada. paper work etc.

    I have decide to build my own. What im looking for is a parts list and maybe some one can fill me in on what kind of pump i need and size of hoses/fittings etc. This would be very appreciated.

    DJ Contracting, I noticed you have made the same thing but i was unable to PM you about it. maybe you can answer some of my questions.

    Below is a picture of what I would like to build.
    Thank you all so much.

    Could not get pictures to work, here is the site.

    Dam, I have been researching that unit and I have herd nothing but BAD things about it. Speed, Clogs, Water needed to dilute mix, etc. Anyone have anything good to say about this unit?

    I know being cheap is the key to success but if you plan to use any catalyst(dryer) or silica, this tank is the worst. If you don't constantly turn and agitate the entire contents you'll get dry sealer in the corners etc.
    PS. polyethalene(plastic) is not suitable for open road use. These tanks are used in vans. The walls are sometimes not thick enough and CAN? break, distort etc.
    This apparatus is not suitable for sealcoating. Most of the THEIF-TIME gypsies use these tanks becuase they cost about $40 at the right store.
    Save your money and buy a a real steel tank.

    As far as the pump go on ebay. It's called a Diaphram pump and takes a compressor and about 6 HP engine.

    Keepoffthegrass The unit that you are looking at will work for you if your looking to get into the business, from experience the unit should last you two or three seasons with changing the pump diaphragm once, cost to put one together if you can find a tank for under $100.00 should be around $700.00 - $800.00. I bought the pump (Inteck transfer pump 5.5 hp) for $239.95 @ Tractor supply. The green hoses that are shown in the picture can also be bought @ TSC, i used 3/4 hose and also built my spray wand out of 3/4 gal.pipe. to make this short i belive i bought just about everything @ TSC and Homedepot. In the short time (Sept.and Oct) that i used it i made just shy of 10 grand so i'm looking for a good year next season, remember this unit will make you enough money to buy the commercial if you continue in the business, good luck.

    I have seen those pumps used for transfer (no sand) but not for spraying.
    The psi will be lower, youll be walking slower. I think that is a impeller not a
    diaphragm pump. 1-4 lbs of sand per gal will put some serious wear on the
    impeller & housing. As the clearence between the two incresses, preformance will drop rapidly. Hose lenght will be limited. I dought it will even
    spray a heavy sand load. My Graco diaphragm pump just finished its 6th
    season with zero problems.
    Thick sealer + 3lbs of sand per = a long lasting job with an antislip surface.
    Time has shown us the only way to mix thick sealer is a steel shaft,arms and
    rubber wipers. A recirculating system will not mix thick sealer correctly.
    A square tank (agine time tested) wont work for thick sealer.

    Just my 2 cents. Hope it was helpful to you.

    Oh, you wanted to hear somthing good about sure looks nice.

    I bought one of these units 4 years ago. It paid for itself in a month. Then if has just been profit since then. It added a whole new dimension to my business. Most all my mowing customers have me sealcoat the driveway in the spring. Best investment I have ever made. I don't know why people cut it down it does a great job and I can do a normal 2X2 driveway in 30 minutes. I think it is because they feel you have to pay alot of money to get the same quality they do. And before you ask I use 2 pounds of sand per gallon and 1 gallon of tarmax. Never had a minutes trouble with it spraying fourth year on my motor, but I think I am going to have to call StarSeal this year for a new motor.

    Don't let everyone talk you out of trying this it really does work!!

    Here guys I will post this for you too.
