Low-viscosity epoxy was used to produce 30 × 120 cm peels of structures in unconsolidated sand. These peels have high strength and good visual impact, revealing both fine detail and gross features with several millimeters of relief. Epoxy was sprayed on vertical trench surfaces and heat-treated in situ using portable racks of heat lamps. Seventy-two peels were recovered out of 80 attempts in one trench.

The method is useful for gravelly sands and for fine-grained to very coarse-grained clean sands. The limiting size for vertical faces seems to be about 0.5 m high by 2 m long.
