This is an appeal from a summary judgment in an insurance contract case. The appellant seeks to hold the appellee responsible under a payment and performance bond for alleged latent defects which were first noticed after the statute of limitations for suit under the bond had expired. Because the statute of limitations had obviously expired, the trial court entered the summary judgment. Section 255.05, Florida Statutes (1965), is the applicable statute of limitations.1
We affirm the summary judgment not only because the lawsuit was not filed until after the statute of limitations had run but also because the payment and performance bond did not insure against the risks described in this suit. A payment and performance bond is an agreement to protect the owner of a building from two particular defaults by a builder. The payment portion of the bond contains the insurer’s undertaking to guarantee that all subcontractors and materialmen will be paid and the performance part of the bond guarantees that the contract to build the building (or road, or utility transmission lines, etc.) will be fully performed. When the architect certifies the building is substantially completed, and the owner accepts the building, then the contractor is deemed to have fully performed and any lawsuit which could be brought against the surety under the bond must be brought within one year, according to the statute. See Miller v. *32Knob Construction Company, 368 So.2d 891 (Fla. 2d DCA 1979).
As we said earlier, the bond in this case would not cover the claims made by the appellant even if suit had been brought within the one year limitation period. The appellant claims there were latent defects in the materials and workmanship which were discovered after the architect had certified substantial completion and after the statute of limitations had run. The appellant contends that the appellee, the surety under the performance bond, is liable for payment because of those defects. We disagree. Once the building is completed, or as we have said using the words of art in the construction industry, “substantially completed,” then the surety under the performance bond is relieved of any further responsibility. The purpose of a performance bond is “to ensure the physical completion of the work upon default,” Guin & Hunt, Inc. v. Hughes Supply, Inc., 385 So.2d 842 (Fla. 4th DCA 1976), and to insure against any losses which the owner may suffer if performance default occurs.
Thus, the appellant’s lawsuit against the surety must fail for two reasons: (1) because the latent defects complained of were not covered by the bond once the owner accepted the building after the architect certified substantial completion, and (2) because the statute of limitations had run.
AFFIRMED.
