Claims Analysis
Total Claims: 32
Claim 1
Independent Claim
71 words
A method of producing a decorative surface having a high profile facing which comprises depositing a particulate material on a planular surface of a fiberglass wall or ceiling board, positioning a gas-curable resin consisting of furfuryl alcohol or an oligomeric acrylate in contact with the surface and the particulate material and contacting the resin with a gaseous curing agent to cure the resin and adhere said particulate material to said surface.
Claim 2
Independent Claim
71 words
A method of producing a decorative surface having a high profile facing which comprises depositing a particulate material on a planular surface of a fiberglass wall or ceiling board, positioning a gas-curable resin consisting of furfuryl alcohol or an oligomeric acrylate in contact with the surface and the particulate material and contacting the resin with a gaseous curing agent to cure the resin and adhere said particulate material to said surface.
Claim 3
Dependent Claim
27 words
The method of claim 1 in which said planular surface comprises fiber glass board, said particulate material is mineral, and said curing agent is gaseous sulfur dioxide.
Claim 4
Dependent Claim
18 words
The method of claim 1 in which said planular surface is self-supporting and has a substantially smooth surface.
Claim 5
Dependent Claim
25 words
The method of claim 1 in which said particulate material is selected from the group consisting of sand, gravel, marble, glass, mica and wood chips.
Claim 6
Dependent Claim
20 words
The method of claim 1 in which said particulate material is positioned on said substrate and rearranged after said positioning.
Claim 7
Dependent Claim
16 words
The method of claim 1 in which said particulate material is pre-coated prior to said depositing.
Claim 8
Dependent Claim
15 words
The method of claim 1 in which said particulate material is coated after said depositing.
Claim 9
Dependent Claim
32 words
The method of claim 1 in which said curable resin is contacted with said gaseous curing agent as said surface, having the particulate material and resin thereon, is moved through a chamber.
Claim 10
Dependent Claim
9 words
The composite produced by the method of claim 1.
Claim 11
Dependent Claim
12 words
The method of claim 1 in which said particulate material is mineral.

Claim 13
Independent Claim
66 words
A method of producing a decorative surface having a high profile facing which comprises depositing a particulate material on a planular surface of a fiberglass wall board or ceiling board, positioning an acid gas-curable resin in contact with the surface and the particulate material and contacting the resin with an acid gaseous curing agent to cure the resin and adhere said particulate material to said surface.
Claim 14
Independent Claim
66 words
A method of producing a decorative surface having a high profile facing which comprises depositing a particulate material on a planular surface of a fiberglass wall board or ceiling board, positioning an acid gas-curable resin in contact with the surface and the particulate material and contacting the resin with an acid gaseous curing agent to cure the resin and adhere said particulate material to said surface.
Claim 15
Dependent Claim
26 words
The method of claim 12 in which said acid gaseous curing agent is selected from the group consisting of sulfur dioxide, hydrogen chloride and sulfur trioxide.
Claim 16
Dependent Claim
47 words
The method of claim 12 in which said acid gas-curable resin is selected from the group consisting of a urea formaldehyde, a phenol-formaldehyde and a furan copolymer and said acid gaseous curing agent is selected from the group consisting of sulfur dioxide, hydrogen chloride and sulfur trioxide.
Claim 17
Dependent Claim
24 words

Claim 21
Dependent Claim
32 words
The method of claim 12 in which said curable resin is contacted with said gaseous curing agent as said surface, having the particulate material and resin thereon, is moved through a member.
Claim 22
Independent Claim
69 words
A method of producing a decorative surface having a high profile facing which comprises depositing a particulate material on a planular surface of a fiberglass wall board or ceiling board, positioning an acid gas-curable resin and a hardener in contact with the surface and the particulate material and contacting the resin with an acid gaseous curing agent to cure the resin and adhere said particulate material to said surface.
Claim 23
Independent Claim
69 words
A method of producing a decorative surface having a high profile facing which comprises depositing a particulate material on a planular surface of a fiberglass wall board or ceiling board, positioning an acid gas-curable resin and a hardener in contact with the surface and the particulate material and contacting the resin with an acid gaseous curing agent to cure the resin and adhere said particulate material to said surface.
