Application On: Interior & Exterior Stucco, masonry, bricks and other concrete surfaces
1. Scraps off loose cement, sand, chalk, duet and other surface deposits and contaminants. 2. Mix 1 part by volume SPHERO CONCRETE NEUTRALIZER to 16 parts by volume water. 3. Using a brush or roller, generously apply the mixture onto the surface, ensure that surface is completely wet. Apply uniformly by starting from the top downwards. Let dry overnight before painting. To test if tghe surface is properly neutralized, test with red litmus or PH paper.
- If litmus paper turns blue then a second neutralization is necessary, if not proceed to the next steop. - If not, proceed to the next step. If on the other hand a pH paper is used and the color that it chanes to correspons to 6 and below in the standard, this means the acid level is higher than acceptable level, therefore was the surface thoroughly with water until it reaches a pH of 7 or 8 and let dry before proceeding to the next step. - If the change in color corresponds to the values of 9 and above the standard, thi means the surface has high alkalinity level thsu a second neutralization is needed and should be left to dry before proceeding to the next step. - If the change on the other hand falls in the standard color level, between 7 and 8, this neans that the levels are within acceptable standards, let dry thoroughly then proceed to the next step in the Painting system.
4. However if treated surface is left exposed for days or is washed down by rain, the egfect of the concrete neutralizer may be nullified. In such cases, test with red litmus or pH paper. 5. Generally c oncrete surfaces take about 28 days or a month to cure. If painting is urgent, a SPHERO ACRYLIC CONCRETE SEALER may be applied. Let dry for 4 hours before applying. 6. Apply SPHERO FLAT LATEX as primer. Dry for 2-4 hours 7.Repair minor imperfections with SPHERO LATE CONCRETE PUTTY. Touch dry in 30min to 1 hour then sand. 8. Apply 2 coats of either SPHERO FLAT, SEMI-GLOSS or SPHERO GLOSS LATEX. Tint with SPHERO LATEX ACRY-COLOR to desired color.
1. Scrape off loose, scaling and peeling old paints. Sand whole surface including tghose where old paint still adhere to surface. 2. For areas with extreme chalking problems, steel brush, blow air from compressor wipe with a clean rag pre-wetted with water. Let dry, then apply 1 coat SPHERO ACRYLIC CONCRETE SEALER. Dryt for at leaset 4 hours before applying subsequent coats. 3. For areas affected by molds and mildews, wipe the whole area with a clean rag with qa Cholorx solution. Scrub using a stiff nylon brush then rinse with water. Leave overnight. 4. Apply SPHERO FLAT LATEX as primer. Dry fro 2-4 hours. 5. Repair minor imperfections with SPHERO LATEX CONCRETE PUTTY. Touch dry in 30 mins. to 1 hour then sand. 6. Apply 2 coats of either SPHERO FLAT, SEMI-GLOSS or SPHERO GLOSS LATEX. Tint with SPHERO LATEX ACRY-COLOR to desired color.
