STUDY OF THE EFFECTS OF SURFACE PRETREATMENT OF CONCRETE AS RELATED TO PAINT ADHERENCE

A PILOT STUDY INITIATED AT THE OHIO RIVER DIVISION LABORATORIES INDICATED THAT INCREASED PAINT ADHERENCE CAN BE ACCOMPLISHED BY THE QUICK AND INEXPENSIVE PRETREATMENT OF CONCRETE SURFACES WITH A MIXTURE OF 50 PERCENT BOILED LINSEED OIL AND 50 PERCENT MINERAL SPIRITS. BOTH LABORATORY AND FIELD TESTS WERE MADE. IN THE LABORATORY, OIL-BASE PAINT WAS APPLIED TO TREATED AND NON-TREATED SLABS OF PORTLAND CEMENT CONCRETE. TESTS IN THE ATLAS WEATHER-OMETER INDICATED SUPERIOR PAINT ADHERENCE OF THE PRETREATED SLABS. THE TESTS OF PAINT ADHERENCE OVER TREATED AND NON-TREATED AREAS SUBJECTED TO ABRASION UNDER THE REPETITIVE LOAD MODEL WERE INCONCLUSIVE. IT APPEARED THAT THE APPLICATION RATE AND CURING OF THE PRETREATMENT SOLUTION WERE CRITICAL IF INCREASED ADHERENCE WAS TO BE ESTABLISHED. THE FIELD TEST AT LOCKBOURNE AIR FORCE BASE, OHIO DEMONSTRATED SUPIERIOR ADHERENCE OF PAINT TO THE LINSEED OIL-MINERAL SPIRITS PRETREATED TEST SECTION AS COMPARED TO THE UNTREATED TEST SECTION. /AUTHOR/
