Spec = I run away & dont bid
I got a kick out of this spec. Talk about unrealistic.
A. Provide manufacturer's written guarantee barrier's performance shall produce a water vapor emission result not to exceed 2.5 (±0.5} pounds per 1,000 square feet per ASTM F1869 prior to installation of floor coverings. Substrates exceeding specified requirement shall be resealed at no cost to Owner.
1. Substrates exceeding specified requirement shall be resealed at no cost to Owner.
2. In the event floor coverings are damaged and independent testing results verify a water vapor emission and alkalinity values, manufacturer and installer shall repair or replace barrier, floor coverings, adhesives and patching compounds at no cost to Owner. Warranty shall not list upper moisture or alkalinity levels. Warranty shall not exclude cracks, concrete cohesive failure, ACI 318, ACI 201, dew point, concrete salts or silicates contamination.
B. Product liability insurance in the amount of $6,000,000 per occurrence listing Architect, and Owner as additional insured. Sub-contractor general liability certificates are not acceptable.
PART 2- PRODUCTS
A. Description: Two-Component, spray applied product for application to newly poured concrete slabs on grade during final troweling process and designed to suppress water vapor mission,
alkalinity, and relative humidity rates from concrete. Material shall be a polymer (non-silicate) based penetrating, film forming barrier that remains compatible with flooring adhesives.
1. Basis of Design: Drawings and specifications are based on the following:
a. Synthetics International; Synthetic 10 TR.
2. Subject to compliance with requirements, provide products indicated or equal products byone of the following:
a. Diamond Stone Products
b. Ardex Moisture Control
2.2 PHYSICAL PROPERTIES
A. Barrier shall meet or exceed the following:
Product Color:Clear or white
Product Type:Penetrating water-based polymer with crack resistance
Thickness:8-15 mills, WFT
Number of Coats:Two-coat process
Solid Content:25 to 50 percent by volume
Spread Rate:Two coats/ 250 square feet per gallon
Flooring Ready:12-24 hours
i. Foot Traffic:8-12 hours
j. Product Odor:Slight odor
k. Environmental:Non-corrosive, water based, water clean up product
a. Vapor Reduction:95 percent vapor reduction
b. Alkali Resistance:Resistance to 30 day exposure to 14 pH in accordance with ASTM 01308
c. Alkali Resistance:35 percent potassium hydroxide resistant in accordance with ASTM 01308
d. VOC Content:50 -65 g/liter per EPA Method 24
e. Concrete Adhesion:600 psi or concrete cohesive failure in accordance with ASTM FD4541
f. Relative Humidity:Suppress 100 percent RH in accordance with ASTM F2170
g. Moisture Emission:Results in a 2.0- 2.5 pounds emission in accordance with ASTM F1869
h. Alkalinity Control:Suppress 12.5 to 14 pH without damage
Oh and I didn't get to the end:
B. Areas above flooring tolerance of 3.0 pounds in accordance with ASTM F1869 are to be resealed at no cost to Owner.
