The synthesis of acrylic latexes filled with silica nanoparticles have been developed in the present work. Moreover, a exhaustive study of the influence of the synthesis conditions on the latex characteristics has been performed. The latex particles morphology has been observed using transmission electron microscopy (TEM) showing a raspberry morphology. Completely transparent coatings have been synthesized using these latexes and a high dispersion degree of the nanosize SiO2 into the polymer matrix has been achieved. These characteristics of these latexes make especially suitable for construction applications (i.e., to protect natural stone). Nanoindentation tests have been carried out in order to measure the mechanical properties of the coating. These tests showed an increment of the elastic modulus and hardness, improving mechanical properties when SiO2 is added to the polymer matrix.
