Abstract
An exterior wall restoration system is applied to an existing exterior wall construction in various layers. The wall restoration system can be utilized to cover damaged or defective wall systems without having to remove a substantial portion of the existing wall system. The wall restoration system includes a water resistant membrane layer, a reinforced cementatious base coat layer, a finish coat layer, a sealant layer, and a final coat layer—these layers are applied over the existing wall system.
Claims11
An exterior wall restoration system for application to an existing exterior wall surface, said exterior wall system comprising:
- a water resistant membrane layer affixed to said existing exterior wall surface;
- an acrylic base coat layer formed over said water resistant membrane layer;
- a reinforcing element embedded in said acrylic base coat layer, said reinforcing element providing structural reinforcement for said acrylic base coat layer;
- at least one furring fastener for holding said reinforcing element in an offset position relative to said existing exterior wall surface, wherein at least one furring fastener passes through said existing exterior wall surface and attaches to an existing framing structure;
- and
- a finish coat layer formed over said acrylic base coat layer.
A method for restoring an existing exterior wall construction having an existing exterior wall surface, said method comprising:
- affixing a water resistant membrane layer to said existing exterior wall surface;
- holding a reinforcing element in an offset position relative to said existing exterior wall surface, wherein said holding step comprises:
- passing at least one furring fastener through said existing exterior wall surface and attaching said at least one furring fastener to an existing framing structure;
- applying an acrylic base coat layer over said water resistant membrane layer such that said reinforcing element is embedded in said acrylic base coat layer, said reinforcing element providing structural reinforcement for said acrylic base coat layer;
- and
- applying a finish coat layer over said acrylic base coat layer.
A method for restoring an existing exterior wall construction having an existing exterior wall surface and an existing weep screed having a first depth, said method comprising:
- removing a portion of said existing exterior wall construction covering said existing weep screed;
- replacing said existing weep screed with a retrofit weep screed having a second depth that exceeds said first depth;
- adding material to replace said portion of said existing exterior wall construction;
- creating, on said material, an exterior surface aligned with said existing exterior wall surface;
- affixing a water resistant membrane layer to said existing exterior wall surface and to said exterior surface;
- applying a base coat layer over said water resistant membrane layer;
- and
- applying a finish coat layer over said acrylic base coat layer.
A method for restoring an existing exterior wall construction having an existing exterior wall surface, said method comprising:
- removing a portion of said existing exterior wall construction;
- adding material to replace said portion of said existing exterior wall construction:
- creating, on said material, an exterior surface aligned with said existing exterior wall surface;
- and
- covering said existing exterior wall surface and said exterior surface with a retrofit exterior wall construction, wherein said covering step comprises:
- affixing a water resistant membrane layer to said existing exterior wall surface and to said exterior surface, applying a base coat layer over said water resistant membrane layer and applying a finish coat layer over said acrylic base coat layer.
A method for restoring an existing exterior wall construction having an existing exterior wall surface, said method comprising:
- removing a portion of said existing exterior wall construction;
- adding material to replace said portion of said existing exterior wall construction;
- creating, on said material, an exterior surface aligned with said existing exterior wall surface;
- affixing a water resistant membrane layer to said existing exterior wall surface;
- holding a reinforcing element in an offset position relative to said existing exterior wall surface;
- applying an acrylic base coat layer over said water resistant membrane layer such that said reinforcing element is embedded in said acrylic base coat layer, said reinforcing element providing structural reinforcement for said acrylic base coat layer;
- and
- applying a finish coat layer over said acrylic base coat layer.
