However, if applying this under the ribbon surely the glue is going to show through in places and I'm going to end up with blobs of visible glue showing through.Necessary cookies are absolutely essential for the website to function properly. The only idea is using glue and in particular I find UHU glue very good for plaster such as crystcal R. ![]() My issue is using double sided tape to apply ribbon won't really adhere to the plaster for long term use. Because the item in question is a decorative gift sculpture and I can place a satin ribbon around the base. I've thought of an idea that would actually suit the base area and hide bubbles from sight. I can smooth out the sides with my finger but it still leaves a few small bubbles that look a little unsightly. Just one further question and slightly randon but is there any suitable way of applying satin ribbon around a plaster base? For example I have a round base approx 4cm high and It always seems to get more airbubbles o the sides more than anywhere else. If anyone can give some clarity on the best plaster to use it would be greatly appreciated. The stronger the plaster the better just to avoid being easily scratched or scuffed but ideally require a reasonably quick demolding and setting time. The item I'm making is a very simple cylindrical sculpture with approx diamter of 11cm x 4cm height. Would crystcast be any better or something like herculite 2 in terms of being not such a bright white and also as strong or harder than crystacal R? I think I've read that herculite 2 was not as strong but the finish is not so much of a bright white. This isn't a massive issue but I just wondered if there was a different plaster that is either the same strength or harder than crystcal R but might produce a slight off white colour once set as opposed to just bright white? The only issue is the areas where the bubbles were seem to change colour slightly once the cast has dried so you get small rounded patterns of a different shade within the bright white cast. The casts come out fine with a few air bubbles in places but as soon as removing from mold I run my fingers over the bubbles and it seems to do the trick as they fill in nicely. I have been using crystacal R so far to make a few sample casts. One further question if you don't mind answering with regards to strength and colour of plasters. I'm going to do a few test tommorrow with a couple of different varnishes I have.
