How do I apply traditional stucco to an ICF?

Tra­di­tion­al stuc­co has a thick cemen­ti­tious base, typ­i­cal­ly installed over a met­al lath. The met­al lath is fas­tened direct­ly to the Fox Blocks webs with screw or sta­ples.

How do I apply an acrylic stucco finish to an ICF?
Acrylic stuc­co is a thin coat fin­ish which can be direct­ly applied to the EPS insu­la­tion on the exte­ri­or face of the ICF. Fox Blocks pro­vides a con­tin­u­ous EPS sur­face con­ducive for the appli­ca­tion of acrylic stuc­co. All acrylic stuc­co man­u­fac­tures are famil­iar with ICFs as a sub­strate and each have their rec­om­men­da­tions for appli­ca­tion over ICFs. Note there is a dif­fer­ence in the instal­la­tion pro­ce­dures between acrylic stuc­co and tra­di­tion­al stuc­co.
What exterior finishes can be used on an ICF?
Fox Blocks are com­pat­i­ble with all exte­ri­or fin­ish mate­ri­als and sys­tems – sid­ing, stuc­co, mason­ry veneer, sim­u­lat­ed stone, etc. The attach­ment of cer­tain exte­ri­or fin­ish­ing sys­tems is rec­om­mend­ed with exte­ri­or grade screws fas­tened into the exposed or con­cealed webs.
Can I leave Fox Blocks forms exposed to ultraviolet rays for an extended period (months)?
Yes, but you will notice a light dust­ing on the sur­face and a yel­low­ing dis­col­oration of the forms. This does not indi­cate any detri­men­tal effects to the ICFs. We do sug­gest, that if the exte­ri­or fin­ish is not going to be installed with­in around a 3 month peri­od or more, the forms be pro­tect­ed from UV rays by installing a tem­po­rary build­ing wrap type mate­r­i­al. The pow­dery film must be removed with soap and water before the appli­ca­tion of a syn­thet­ic stuc­co fin­ish or water­proof­ing mem­brane.
