Foam sculpture is made of foam as the main raw material, according to certain requirements, shape, proportion, shape, size, and performance, and made into certain foam sculpture crafts.
It has the advantages of lightweight, low price, and short production period, so it is called “fast food sculpture”.
Foam sculpture is widely used in exhibitions, outdoor advertising, commercial space decoration, festival model, brand promotion visual image, place scenery, wedding film props, courtyard landscape, decorative components, and indoor and outdoor relief murals, etc.
It can also be customized according to the requirements of large crafts, theme parks, architectural decoration, etc.
But the just-made foam sculpture is very fragile and easily damaged, which is not conducive to preservation and transportation, so we usually do the hardening treatment on its surface.
At present, there are three common methods of hardening foam sculpture.
One: simple hardening
1, in the foam sculpture surface evenly coated with a layer of water-based putty or fast-drying plaster, etc., to be dried and sanded smooth, and then carefully and evenly sprayed on the surface of the decoration with wall paint for isolation.
2, and then spray acrylic or primer and top coat for processing, and then spray on the waterproof reinforcing agent to wait for air-drying.
3, after the above simple hardening, foam sculpture has a certain strength and good resistance to weathering.
Two: Resin hardening
1, is coated with polyester resin or epoxy resin on the surface of the foam sculpture for FRP treatment of foam sculpture (can be brushed or dipped).
2, according to the required strength and thickness of the one-time processing or multiple processing, the surface of the foam sculpture after processing an formed a hard FRP shell layer.
3, the hardening process is the need to use the glue and then used for surface isolation to enhance the toughness of the foam surface, it can effectively isolate the paint, thinner, resin, atomic ash and other substances on the surface of the foam corrosion burns, thereby enhancing the toughness and strength of the foam sculpture.
4, the specific method is to take out the appropriate glue to add filler (wall putty, line corner white, white cement, etc.), in the mixer to make the glue and filler fully mixed table, saturated to no particle sense before use, wait for the completion of hardening treatment in the primer and top coat.
Three: Polyurea spraying
1. The polyurea material will be sprayed directly on the surface of the foam material by the special polyurea spraying equipment, which will produce a layer of elastic protection with uniform thickness and smooth surface in a few seconds.
2. Polyurea enhances the foam sculpture, it has high designability, long service life, low cost, easy maintenance and high environmental protection.
3. It has the characteristics of high spraying efficiency, making products with flat surface, unlimited construction area and thickness, multi-layer spraying without delamination, making realistic scenes, protecting the foam sculpture from breaking and good reproduction of the original shape.
4, Spraying polyurea material is widely used in foam sculpture industry, including the skin protection of wedding film and television props, waterproof and protection of theme parks, water parks and various riding facilities, stage sets, advertising exhibits, antique building protection, etc.
5. after spraying polyurea coating foam sculpture, not only can withstand the wind and sun and rain, but also not afraid of falling / touching, colorful at the same time, but also more convenient transportation, no longer afraid of accidentally to touch broken.
6. the construction process is greatly simplified, but also more convenient and fast.
The above is for you to organize the foam sculpture surface hardening treatment of some knowledge points, I hope to bring you some help, if some are not mentioned, welcome the comments section to add!
