Articles
Resco Products, Inc. furnishes both plastics and ram mixes. All of the products listed here are supplied pre-mixed, ready to use. They are supplied in cartons and/or pails.
Installing Plastic Refractories
- Use of a pneumatic rammer with a metal, the convex-shaped head is recommended.
- Use rigid forms for arches. Proper anchoring and support are essential.
- When patching, clean the surface thoroughly, and for best results, apply a coating of compatible high temperature bonding mortar before installing the plastic.
- Trim surface while plastic is still soft. Do not smooth the surface-a rough surface allows moisture to escape.
- Moisture escape holes are recommended for the hot face. Use a 1/8” diameter rod with a pointed end.
- Insert the rod approximately two-thirds of the thickness of the plastic on not more than 6” centers
- To control cracking in installations with large surface areas such as walls or roof sections, construction joints should be formed by scoring the surface of the plastic. Score to a depth of 1.5”. Score lines should be on 36” centers, vertically and horizontally, between anchors
- Drying and heat up should be started as soon as possible after installation is completed.
Suggestions for Installing Ramming Mixes
- Use pneumatic rammers with wedge-shaped steel heads. Never use rubber heads
- Always use rigid forms, preferably steel.
- Do not ram over loose, unconsolidated sub bottoms
- Material should be placed in approximately 2” layers of loose material and compacted. A steady flow of material is desired to prevent laminations. Ramming should be continuous to prevent material dry out between layers.
