Jaime I concur that your Buildings are superb. Though a picture tells a thousand words some of the Techniques are perhaps a little lost without some words. Most I get but the revealed Brickwork how did you achieve this? Did you hack away some of the Foam and put in Individual Bricks with some filler to blend in the sides?
Hi
Thanks for your words, and really, the brickwork deserves a more detailed explanation. This house is my first building made for my 1:32 layout, and the brickwork is different to how I do it now. Here I work with 1:32 bricks from juweela brand, but the results are very homogeneous, the bricks are very perfects, very news, and I prefer the wheatered walls. The mini WC attached now is made with the new technique that I use. First I ´ve made tools from old paintbrushes without bristles. Then I shaped the ferrules into the form desired with fine pliers.
This tool is used to emboss the surface in the foam, I used a metal ruler as guide. Missing bricks or fisures can be simulated with a needle.
Then two coats of humbrol 28 were applied with a wide brush
Polish the surface with 400-grade sandpaper (after 48 hours) to give the bricks a texture.
The brickwork is painted with acrylic paints by Talens, burnt Sienna 411 and red 339, mixed with matt black or simply just this two colours in various mixes.
The mortar courses between the bricks are simulated using white pigments applied overall, onto the surface of the bricks with an old, wide brush
After the excess pigment has been blown out, the remaining can be embedded into the joins with just your fingers.
More shades of acrylics colours were given to random selected individual bricks with a fine number 2 size brush
Green pigments can be applied for simulate the humidity.
Best regards

Many thanks Jaime, I was asking about the process of the Brickwork that is in this picture where Brickwork has been revealed by the Surface Render being detached. There are clearly a few different techniques occurring here. But the other processes were also most interesting and informative as well.
Thanks Jaime. You make it look easy but I bet it's really difficult to get that sort of finish. Like Jon, I'd be intetested to see how you get the effect of cracked and peeling plaster as with your first building.

Ohh, ok , well, I am used “ready to use” plaster, in Chile “pasta muro”, a product for wall repair. The first step is to apply a thin coat of approximately 1 mm on the foam surface. When it has dried, I draw cracks with a pencil then I used a needle or a ophthalmic micro knife (disposable) , both are good. The engraving really is soft, however, of the groove is too deep, you can always rectify it by applying more plaster.
Then I used the paints, first 2 coats of Humbrol 28, then more humbrol enamels , gray and beige, alternately with a synthetic sponge, in small areas. The aim is to blend the colours. The cracks are underlined with matt white enamel or with ivory o white acrylic paint (Vallejo brand).
Now I used the heavy chipping fluid (Ak interactive), 2 coats with a large flat brush. Then I paint the surface with acrylic colours, with sponge too. I used Vallejo stone gray, dark gray, ivory, and white. Mixed together onto the surface to obtain infinite combinations of colours typical to the rendering of old stucco.
Then it´s the lenght stage regarding chipping with clear water.
Here a video with the chipping process, you can see the old blue paint imitation.
Well, I accept questions, my english is regular, but I tried to explain the complete process
Best regards

Thanks Jaime
That makes perfect sense, thanks. Just a quick question, is your pasta muro a ready-to-use paste or a powder which needs to be mixed with water when you buy it? It sounds like something we call "Polyfilla".

Hello Rik
The product is ready to use, coat the surface 1 mm aprox, wait to dried, apply a fine sand paper, and you can apply a new coat for leveling, then wait to dried, and sand paper again. Polyfilla?, may be , you must try... there is another products that I think exists in UK

I think that is the same to Pollyfilla

Sounds very much like an internal Wall Plaster as you say Rik. Not sure how that would fare outside in the UK Frost. Similar effects that will live outside can be carried out using External Grade Wall Tile Adhesive. This building was done with some many years ago like back in the mid 1980’s so is allowed to be a little weather worn now. Only problem is that one needs to buy in in pretty large packets, but not so large as a bag of Cement. Back in those days I would not have been aware of the benefits of pre coating with External Grade PVA and perhaps using a little very sloppy PVA mixed in the water when mixing
sorry to hijack your build Jaime.
One thing more, “pasta muro” exists in two versions, for interior and for exteriors, the second option does not work, it’s not crack with the needle, it’s similar to plastic.
Jejeje no problem!!!!! Thanks for show your experience!!!!
For me the interior filler doesnˋt problem, I keep my buildings inside the house
