Recoating EIFS 1 02, EIFS finishes are easily recoated to refresh the look of the. cladding or to change the color Sto produces coating. products engineered specifically for this purpose StoCoat. Lotusan is the preferred coating product for this application. Lotusan is an exterior wall coating modeled on the. microstructure of the lotus leaf This BIONICS technology. engineered by Sto imparts super hydrophobic properties. the Lotus Effect to the coating This helps the coating. stay cleaner longer StoCoat Acryl is another Sto coating. that can be considered for this purpose when atmospheric. pollutants are less of a concern If hairline surface cracks of. less than 1 32 0 8 mm in width exist in the EIFS textured. finish StoSilco Lastic is recommended as an alternative It is. a high build 10 17 dry mils elastomeric coating designed to. provide needed crack bridging Before recoating the finish. surface of the EIFS must be sound and free of defects such as. peeling blistering cracking or delamination Surfaces must. be thoroughly cleaned to remove contaminants including dirt. and mildew that might affect adhesion of the coating Refer. to procedure number ER 1 01 Cleaning EIFS for detailed. cleaning recommendations Select colors with light, reflectance value of 20 or greater for use with EIFS.

Resurfacing EIFS 1 03, Resurfacing of EIFS is sometimes done for cosmetic reasons 3 Apply Sto. for example to restore the original appearance of an aged base coat to the. EIFS finish or to change color texture or both thereby surface with a. renewing the appearance of an EIFS facade It may also be a stainless steel. more economical way to fix excess surface cracking or some trowel to a. other repetitive surface defect that exists in an area of the uniform.

Important Note the reinforcing mesh is not an important functional component of the resurfacing. work unless, 1 There is a desire to increase impact resistance of the EIFS.
Fig 1 2 It is needed to reinforce surface defects such as cracking. Do not resurface an area up to an arbitrary line or it in some way is being used to remedy other deficiencies. since it will not match the adjacent area 1A If neither of these conditions exist the reinforcing mesh can be omitted and the wall surface can be. Resurface up to an architectural break in the resurfaced with Sto RFP followed by Sto finish One should bear in mind that the mesh does aid in. wall or resurface the entire elevation for leveling the wall and in controlling thickness of Sto RFP The decision to incorporate it into the. a uniform appearance 1B resurfacing work should be made on a job by job basis.
