Model Railroading > Hydrocal Plaster

For all you folks who were looking for Hydrocal Plaster a couple of days ago, there is a place in Penn. that sells it again on ebay. Go to Hydrocal for the headline, scrowl down to the Hydrocal Gypsum Cement, (It is in a brown box, comes shipping free, 40 lbs. for $39.00, also there are auctions for 25 lbs. starting at $9.99) I have used this with GREAT results, very strong when sit up. I have built many mountains out of this. The manufacturing name is Robert Forrester Company.

Good to know. The shipping is usually very high.

Even when you get it on a bid from ebay, shipping is only $10.50 for 25 lbs. I've seen him have 25 lb. boxes on a buy-it-now also, free shipping. Good stuff guys, have used probably 200 lbs. of this.

Most building supply houses for contractors will carry this in 100lb bags for less then $20.00 here in California.

Agreed, but I don't need that much as just build bridge abutment, piers, etc., from time to time. And the smaller quantities come in a plastic tub that has a longer shelf life than an opened bag.

Have you tried "Ultracal 30" for bridge piers, abutments, etc..... it is stronger and shrinks less when dry

No, will have to try it sometime.
