Credit IEQ 4.1, 4.2, 4.3: Wood Floor Sanding Sealer

Yes - the product should be input in both credits.

Hi Brianne,

I would agree with the reviewer that they should not be listed in IEQc4.1 because they technically don't meet SCAQMD 1168 definition of a sealant, which is "any material with adhesive properties that is formulated primarily to fill, seal, or waterproof gaps or joints between two surfaces. Sealants include sealant primers and caulks." I would also agree that it should go under IEQc4.2, but not as a Floor Coating. Even though this is going on the floor, floor coatings are listed as "opaque coatings that are formulated for or applied to flooring, but not limited to, flooring garages, decks, and porches. Floor coatings also include clear coatings formulated or applied to concrete flooring." I would think that you could list them under "clear wood sanding sealer" and "varnish" for IEQc4.2.
I'm not exactly sure what you would list them under in the IEQc4.3 form, considering these designations are not listed within the form. It's hard to believe that LEED would require projects to comply with the 100g/L for a Floor Coating considering the most low VOC commercial products for sealing Gymnasium floors aren't even close to 100g/L. If anyone else has any suggestions or think my methodology is incorrect, please let me know. I am working on a project that has the same problems, although the products specified on ours have not been used yet and I have a chance to change if substitute is available.

Thanks,

I have a question that goes along with the original post, and John-David's response. We have sealed concrete floors, and the contractor inadvertently use a concrete sealer on the floor that, using the VOC budget calculation method, makes us unable to attempt IEQc4.2. I am a little unclear if this means we will not be able to pursue IEQc4.3? The product does not meet the SCAQMD limits for VOC's. But the way I am interpreting IEQc4.3 is for flooring products, and we wouldn't double count the concrete sealer. However, John-David's response has me questioning this logic. Any insight is appreicated!

IEQc4.3 is an all or nothing credit.

Hello,

We have a similar concern with our school gym flooring product. Based on the data I have on the product, it appears it should be categorized as a floor coating with a limit of 100g/L, but is 327g/L. It is a clear product, that is moisture cured urethane and can also be used on concrete. For this reason, I feel it cannot be defined as a wood coating per SCAQMD 1113 definition for wood coating: for wood substrates only. Would you agree? I am wondering if anyone has submitted a project recently with a gym floor coating and what was the outcome? Also, if we were to look into the VOC budget approach, can anyone confirm if this can be applied to IEQc4.3?

I think I see what could be causing some of the confusion. the LEED NC v2009 EQc4.3 form (v. 5) has table required tables. One is for flooring adhesives & "sealants." the other is for actual floor products (ie. wood boards.) The 1st table for adhesive/sealant doesn't have any "drop down" categories to list a "coating" but one could list it as "other sealant." Therefore, there is slight languistics confusion in that table if one has a floor "coating."

The LEED NC v2009 reference guide however says: "...wood...sealer, stain and finish must meet scaqmd rule 1113 in effect 1/1/04) which relates to Ref guide Table 1 in EQc4.2 (& not credit EQc4.1.)

Keep in mind that all pre-finished wood (gym) flooring all must be FloorScore or Greenguard Gold certified

but unfinished wood gym flooring would just need to be NAUF (if composite wood and going for EQc4.4)

and the coating/sealer meet SCAQMD rule 1113 per 4.2.

 So seems like floor "coating" needs to be listed in both EQc4.2 and EQc4.3 for NC v2009.

Thanks for this thread!  I had the exact sames questions about the same Poloplaz product!  Was also looking at 4.1 instead of 4.2.  

Hi All,

With reference to the above thread, has anyone got awarded the credit IEQc4.2 - Paints & Coatings - by considering the wooden floor coatings allowable limit based on "Clear Wood Finishes" instead of "Floor Coatings"?

Please clarify.

Yes they're different. SCAQMD Rule has definitions in the rule. "Floor Coatings" defined does not include clear wood floor coatings. That product would fall under the type clear wood coating it is "ie. shellac or other." Debra
