Hard Blok - Block Filler

Greg Reimer 7376 · 11-15-2009, 01:07 PM

Make sure all freeze plugs are out, hot tank, wash out and then use only brass freeze plugs before using muriatic acid.Make sure the drain plugs are out, rinse and dry the block thouroughly, then install the filler one side at a time as was suggested with a day or two in between. Take your time and do it right, as I know of no way to get this stuff out if you do it wrong.Make sure you do the acid in a well ventilated place because it will stink up the place, and the fumes are corrosive.

I have found that it bonds to the block/cast iron surface a little better when the water jackets are a little wet/moist.

You should at least wear some sort of cotton or gauze mask to keep the inhalation of the vapors to a minimum, even when using muriatic acid outdoors.

Thanks for the replies.
Yes I know muriatic is ugly stuff to work with. I have the proper respirator/cartridges for that chemical as well. Like I said earlier, I've filled blocks in the past and had the best luck using muriatic acid, but I thought I'd ask. Sometimes new ideas come along.

Thanks again.
