This article establishes procedures for inspection, acceptance and reporting of concrete sealers for the protection of concrete against damage from deicing chemicals. Refer to Sec 1053 for MoDOT’s specifications.


1053.1 Apparatus

a) One quart (1 liter) screw top cans, which are clean, dry and free of all contaminants.

1053.2 Procedure

1053.2.1 Pre-Acceptance Lists

Manufacturers and Brand Names of concrete sealer will be placed on the Pre-Acceptance Lists maintained by the Central Office in accordance with Sec 106.

1053.2.2 Manufacturer and Brand Name Approval

If a manufacturer desires to have material added to the Pre-Acceptance List of concrete sealer, a certification and guarantee must be submitted to Construction and Materials in accordance with the requirements of Sec 1053. The certification and guarantee shall be accompanied by a sample of the material for laboratory testing. Upon approval of the material, it will be placed on the Pre- Acceptance List.

1053.2.3 Mixture of Boiled Linseed Oil and Petroleum Spirits

Boiled linseed oil and petroleum spirits components may be provided by a manufacturer that is not on the MoDOT Pre-Acceptance List. These components shall be mixed in equal parts for use as concrete sealer.

1053.2.4 Basis of Acceptance

Branded pre-blended boiled linseed oil and petroleum spirits shall be accepted in accordance with Sec 106. Boiled linseed oil and petroleum spirits components shall be accepted in accordance with Sec 1053.4. The components may be accepted by label analysis or certification and are subject to random sampling. Certification for components may be an invoice, or other documentation that declares the original source of the material and what material is being provided.

1053.2.5 Sampling

Each producer or supplier will be assigned to a district office for Facility Review, Sampling and Testing in accordance with EPG 106.12 Pre-Acceptance Lists (PAL). During the visit, samples of material available at the facility should be obtained. Materials selected for sampling will typically be those that have been used in MoDOT work during the past month. Material originating at locations too far from the assigned district’s office is subject to sampling at an intermediate location or at the jobsite. It is the assigned district’s responsibility to coordinate with the supplier and other districts to assure the proper materials are sampled.

A sample of branded pre-blended boiled linseed oil and petroleum spirits, or either component shall consist of one quart (1 liter) of material in a screw top can.

1053.3 Report (Records)

Samples shall be recorded using SiteManager showing the manufacturer’s name, the brand name, lot number, net quantity represented, and the location where the sample was obtained using the Sampled From and Sample Origin fields of SiteManager. If the material is sampled after having a PAL ID assigned to it, the “Link To” field should be used to link the two sample records in SiteManager. Test results on random samples of concrete sealer will be reported by the Central Laboratory.

For material shipped directly to a job site by a supplier, the supplier shall notify Construction and Materials prior to shipment using General Section 13 Form 3. When complete and correct information on the shipment is provided to Construction and Materials, a PAL ID number will be assigned to the material. That number shall accompany the material in shipment and be immediately available until the material is consumed.

Material purchased for maintenance work may be accepted solely on the basis of the manufacturer and brand being on the Pre-Acceptance List or on label analysis, certification or detailed invoice for components. District materials will report the receipt and acceptance of the material in SiteManager and will mark the containers with the Sample ID number they assign.
