We study the thickness ${h}_{d} $ of the liquid film left on a wet surface after scraping it with an elastic wiper (length $L$, rigidity $B$) moved at a velocity $V$. The scraper is clamped vertically at a given distance above the substrate, and ${h}_{d} $ is maximal when the tip of the scraper is just tangent to the surface. We show experimentally and theoretically that this maximum thickness is ${h}_{\mathit{max}} \simeq 0. 33L \mathop{ (\eta V{L}^{2} / B)}\nolimits ^{3/ 4} , $ where $\eta $ is the liquid viscosity. The deposition law is found to be sensitive to the shape of the wiper: the film thickness can also be tuned by using wipers with a permanent curvature, and varying this curvature.
