  1. Alan,

    The difference is huge! At one time I was using 14 GPM. That is not possible in a lot of situations though.

    The impact at the surface has much more force with 8 GPM, so every revolution of the bar you remove more dirt, oil, etc. per pass of the bar . Which lets you push a surfacer faster without stripes.


  2. F-13 is a potassium hydroxide (alkaline) based product with 5% by weight.

    F-13 is a general purpose degreaser that works well on siding and also gutters. It can be diluted up to 100-1, for general house washing I recommend 40-1.

    It can be mixed with sodium hyporchlorite to kill the mildew. Be sure to mix in a container that can breath. Only mix what you need, after mixed it will have a shelf life of about 2 hours.


  3. Good choice! Next you need to buy the pressure washer that will work with the hot box you will buy in the future. If you decide to go with an oil burner your options are 12 volt or 115 volt models. If you decide on the 12 volt buy a pressure washer with a 20 amp charging circuit and enough room to mount a larger battery to keep up with the need of the burner. The 115 volt will require a generator.


  4. Bullet, shooter and that thingy that shoots a straight stream of water up to 40 feet depending on the GPM of your pressure washer.

    This is the method that I have used for years. Adams injector to apply chems. The use of various nozzles depending on the situation. If you use a 0040 nozzle it will pull chemical and shoot about 40 feet depending on the GPM of the pump. This nozzle gives you a bullet stream, but the pattern is round and tight. So I use a round steam nozzle blank, drilled the correct hole size to match an #40 orifice. The steam nozzle has about a three inch barrel and the pattern is more of a fuzzy bullet ( for lack of a better term ) that allows you to more evenly apply the chemicals and still shoots the chemicals to the same height.

    If you want this method to apply chems with a ratio of about 4 to 1 ( depending on the GPM of your pump ), plumb a Shur-Flo pump into the chemical pickup line that goes to the injector. the will boost the injection rate.
