> I addressed the issue of spray-on siding (also known as liquid siding)

> The application of any of these types of sidings requires a high 
> pressure
> wash of the exterior wood siding or brick. Once the exterior is power
> washed, the siding is then sprayed on to about the thickness of a 
> credit
> card. The manufacturers of these sidings claim that the exterior 
> finish will
> last 25 years or more.
> This siding material has been marketed for buildings for less than 10 
> years.
> There are numerous lawsuits regarding this type of material which can 
> be
> reviewed at the HADD website (Homeowners Against Deficient Dwellings). 
> These
> lawsuits primarily center on poor workmanship and rapid failure of the
> siding finish. The manufacturers of these siding materials have also 
> been
> forced to drop their claims of insulation since these claims are 
> unproven.
> Those in attendance in South Carolina had concerns about permeability 
> and
> the diminishment of details. There was also the question on whether or 
> not
> this product was reversible and the Liquid Siding representative did 
> not
> have a substantive answer to this.
> At this point I would proceed with caution on these products simply 
> because
> we do not have enough of a track record of their permeability, 
> durability,
> and overall impact on historic materials. I am not aware of any way to
