how much hardner do i need for 4.35 gallons?

The resin and hardener come as a 5 to 1 ratio. The resisnt exactly a gallon, the hardener in I think a 25 oz can goes with a “gallon” of resin so you would need to get five of these 25 oz cans of hardener and you’ll have 2/3 of a can of hardener left when you’ve used up your 4.35 gallons of resin.

I have used Envirotex Lite to coat tiles and it is crystal clear but SO long to cure. Question is if this is crystal clear? And how long to cure?

You have to use 207 hardner and 207 resin. Go to West system site and read about clear finish.

Do these containers come full ? appeared to have channellock marks on lid channel and there was hardener on inner lid. Missing 2 inches of product.

It doesn't matter. It was obviously opened by someone. Just return it and get another one or a refund.

My set of resin and hardener came today, but the hardener is brownish/redish in color when I pump it out. Is that correct or should I return it?

My hardener was slightly brownish when mixing with the resin, but after mixing it would clear up, and it would harden clear as well. If it is very pronounced, you may have a problem, but if it is just a tint that goes away when you mix, that seems to be normal. You may want to do a test on some scrap material to confirm.

West System Products are Great!

West System Products are wonderful for both hobbyists and professionals. Convent package sizes make it easy to buy the right amount without waste. 205-B is great for cold weather or fast cure needs.

Delivery ahead of schedule

Timely delivery of product is always desirable. West systems offers among the best performance for an adhesive and structural epoxy. Not to be confused with a slow cure or high depth of pour product.

Know quality,know WestSystem. No quality,no WestSystem.

Can't go wrong with West System. This is the fast hardener, compared to the Slow. Duh. The other pic is of their 404 high-density filler. I use it to make the epoxy thicker. I have dyed it also to make it match the color of wood. Works great! Thanks West System, your a good guy.
