That depends on the effect you want. You get a white, paste-like consistency with SOLO GOYA Acrylic Structure Paste Universal. It is a great medium for basic applications. And you can colour the white structure paste with a bit of acrylic paint, e.g. with SOLO GOYA Acrylic. The result, however, is pastel in colour as the white paste lightens the colour. SOLO GOYA Acrylic Structure Paste Fine Sand conjures a fine-grained surface. How about some small cracks by design? You can get that with SOLO GOYA Structure Paste Antique Effect. 

Shimmering metallic effects are created with SOLO GOYA Acrylic Medium Structure Paste Granite Silver or Brilliant Gold. White structure pastes dry to a matt finish. If you like glossy, transparent elevations your artwork, then go for a gel: SOLO GOYA Structure Gel Glossy or the Crystal Pearls version. 

Can’t decide which structure is right for your artwork? SOLO GOYA Acrylic Medium in a set of eight 20-ml tubes comprises different media in practical try-out sizes. 
 

The easiest way to create structured art is on a canvas frame. You can prime the white canvas with acrylic paint first. But it is not necessry to prime the canvas before you apply structure pastes and gels. We use a palette knife to put a dollop of the medium at the edge of your artwork. We have chosen SOLO GOYA Acrylic Medium Structure Paste Granite Silver as the metallic effect really catches the eye. Now spread the splodge of paste to create an arc. Then use a serrated palette knife to make furrows in the paste. That works best with a slow, but sweeping motion. Not happy with your results? Then use the palette knife to smooth the paste and make new grooves. This is possible as long as the paste has not dried. 
 

Creating with SOLO GOYA Acrylic Structure Paste is totally easy. In seldom cases, cracks can form during drying. If some cracks do form, then moisture is usually involved. Perhaps the priming paint was not completely dry when the paste was spread on top. We recommend working on canvas as surfaces like wood or plywood store moisture. 

If the ambient air is too dry, that can also cause cracks in the structured art. So we recommend that you air the room properly before you get creative. A thinner application of the structure pastes is better. Thicker layers store more moisture and dry more slowly. If a crack does form, you can use SOLO GOYA Acrylic Structure Paste to simply cover it over. Leave everything to dry thoroughly.
