Restoring the Mantel

" That's a pretty interesting technique of stripping paint Greg. What was it you just said?"

" Well, I've just vacuumed off a methylene chloride-based stripper that I've been using on this heavily over painted ornament here on the mantel. "

" It sure is heavy, I'll give you that."

" It's a commonly available stripper you can get at the paint store or the hardware store."

" Uh huh. Well, I think this miracle here was mostly all stripped now. Is that the process you used for the whole thing?"

" No. Actually, on most of the flat surfaces, the profiles, these columns----"

" Yeah."

" I use the heat gun----"

" Okay."

" and various profile scrapers----"

" Uh huh."

" such as just one or these 2."

" Yeah."

" This one works very well in these fluted columns."

" Right."

" By moving it back and forth, you can get into the profile quite nicely."

" We'll just use that with the heat gun."

" Right."

" And what's this---- What would this one here be used?-This is excellent for very tight corners. And here, you see I'm running along the grain of this profile----"

" Okay."

" but I am not scraping against the grain----"

" Right."

" or this flat surface here."

" Yeah. Very nice."

" This one also works very nicely in---- against flat surfaces where you've got a rounded surface next to it of which there are quite a few actually----"

" Yeah."

" on this mantel, on all 3 of these mantels."

" And what's with the process now? Did you do the same thing up here on these musical-looking beauties here?"

" Right. These wires have to had several applications, probably as many as 6 or 7 applications of stripper. And, as you saw, I used the scraper----"

" Okay."

" while the strippers on there to get down into the profiles, and then ultimately, without a stripper on there, I would dry scrape as well. And you can see I'm getting the last little residues of weight----"

" Right."

" after between each of these individual strings, which are fairly delicate."

" So no heat on these details here."

" Correct. This ornament cannot withstand high temperature. They are made of among, other things, hide glue, which is made from animal hides."

" Alright. Okay. Yeah."

" Hide glue, linseed oil, saw dust."

" So this is how they are originally made. They put them in a mold?"

" Correct."

" Put them out and attach them?"

" That's correct."

" And I see we've got one over here that we're----"

" Right. Over here, I have an entire mantel basically fully strips----"

" Okay."

" and in fact, I'm now repairing ornaments."

" So this looks pretty much like the one we just left."

" It is very similar in construction. The only difference is the motif. In the freezer area here----"

" Okay."

" where we had lyres and other musical motif there, we have here a----"

" Little dolphins there?"

" We've got dolphins and other seafaring emblems."

" Okay."

" We also have a Masonic symbol here in the center of these 2 panels."

" Okay. Now, we've seen how they've been applied before in past jobs, but I understand you're not doing the composition here. You're doing something different."

" That's right. What I'm doing is completely different in appearance. I'm using Plaster of Paris, mixed with a bonding agent, which I'm adding right now to some cold water. Here's my bonding agent. I'll be using this as an add mixture to which I then add Plaster of Paris, mixing that to about the consistency of toothpaste. I always and the powder to the liquid. Mix it fairly slowly, but with Plaster of Paris, as you know----"

" That's not [unk]."

" You don't have a lot of working time."

" Right."

" So Ryley, I'm using a 1:1 ratio here between water and the bonding agent in my Plaster of Paris mix. Okay. Now, I'm applying the bonding agent right to the surface of the mantel. Well I can see that the bonding agent is ready now, and so is the plaster, so I'm gonna put on these magnifying glasses. And,"

" I'll just say that everything a little better?"

" Absolutely. And I'm gonna lay on a very rough initial application of the plaster to the location that we're gonna be returning."

" It's almost like miniature trowel work."

" That's exactly what it is. I just wanna be sure I have enough in place so I can come back in a while and smooth it out."

" Now Greg, why not use some of the materials that are out now for as wood fillers to do this work as opposed to Plaster of Paris?"

" Well, it's a preservation philosophy that we don't want to fool or trick or confuse any future conservators should they come along and want to strip and trace the history of this panel."

" They wanna see that this is a repair. They don't wanna be confused."

" Correct. So these are gonna be very obviously repairs out of a completely different material."

" And I've got to ask you what are all these red tapes for?"

" Those indicate locations where I have got work cut out for me."

" Looks like they're a lot."

" The missing ornaments in about 30 locations."

" Yeah."

" Some are very simple. Some are rather more complicated. We have a flower down there that I have already done some work on. Others are very simple where they are just big blisters that simply need to be filled in and smooth out."

" Now do you have any special tools for the actual carving?"

" Well, I've been using anything that works really, but specifically, I've got some very small hobby knives----"

" Okay."

" which works well."

" Can we see how you use them?"

" Yeah. I've some here, a couple of pieces that I laid up earlier today. I come back now and shape these, using the Exacto knife. Really works well at this stage. I also have dental picks I use. The very nice thing about the bonding agent I use is it makes the Plater of Paris workable for a much longer period of time and regular strip plaster repair."

" Very nice."

Planting a Perennial Flower Garden

Ruth Foster, a landscape consultant, oversees the planting of the perennial flower border in the yard. Smaller plants fill in the front, moving to the tallest flowering plants in back. Foster has chosen deer-resistant plants like summer asters for the front, with echinacea or cone flowers behind. Foster has also selected a vivid, neon autumn joy for the garden. She and Bob look at the early blooming magnolias that have been planted in the yard and the euonomous hedge that will grow to eight or ten feet and turn red in the fall.

Mulch Options
Mulch Options

Here s another great tip from BobVila.com. Mulch is probably the best tool you have to keep your garden healthy and green this summer. There are lots of different kinds of mulch to choose from, depending on what s in your garden and what s available where you live. Wood or bark chips, compost, straw, salt hay, cocoa husks, shredded leaves, plastic sheeting and even gravel can all make good mulch for different reasons. In the right quantities, they serve as a shield for the soil so it can do its best work. Mulch protects the soil from erosion and helps it retain its moisture so you can water less frequently and roots grow deeper and healthier. It also keeps weeds down, reserving precious nutrients for your vegetables, flowers and shrubs so you don t have to add as much fertilizer. You spend less time and energy weed whacking and don t need to use poisonous herbicides. After you ve mulched everything once, you don t necessarily have to spend a fortune every season on new bags of commercial mulch. As a matter of fact, be careful of mulching your garden with anything that attracts pests or contains dangerous chemicals, especially on vegetable gardens. Adding some organic material might be enough. Autumn leaves are a gift to your garden that literally just falls out of the trees. Instead of getting rid of them all, put them through a leaf shredder or just run over them a few times with the lawnmower, rake them up and use them as fall mulch on flower or vegetable beds with a little fertilizer. You can add compost to them and turn them into the soil in the spring. In play areas or anywhere you don t want to maintain a lawn, try a recycled mulch like rubber chunks from used tires that would otherwise sit in landfills.
