4. BARE CONCRETE Unpainted concrete new or old is rarely ready to be painted as it stands It is generally recommended that new concrete or masonry swimming pools age for at least two months before painting The pool should be filled with water during this period to dissolve salts in the concrete Plaster lined pools require at least 30 days to cure If grease oil and dirt are present remove with a strong cleaner such as TSP TRI SODIM PHOSPHATE Rinse the surface thoroughly to remove all residue after washing and allow to dry before etching All new concrete pools should be acid etched with MURIATIC ACID Dilute the solution 1 part acid to 4 parts water in a 5 gallon bucket and use a scrub brush to apply to the pool surface Etching cleans the concrete and prepares the surface to hold paint It produces a micro roughening of the masonry finish to make it more porous and to neutralize the alkali on the surface The etching product should be applied to the concrete at a rate of one gallon per 200 500 square feet Apply with a stiff brush or sprayer and permit the solution to stand for at least 15 minutes or until the surface stops foaming and bubbling Then hose down several times with plenty of water to be sure that no contaminating materials remain NOTE It is extremely important to remove all the acid from the surface or the paint will not adhere well The surface should dry thoroughly before painting Protect your hands feet and eyes from th
5. G TO APPLY POOL PAINT A USING THE PAINT If it is extremely warm you will find it more comfortable to paint the east and south sides of the pool in the morning hours the west and north sides in the afternoon With this method the walls of the pool allow you to paint in the shade The paint will dry rapidly enough and be easier to apply The corner of the pool is a good place to start Begin at the top and work down from left to right so that the danger of running or dripping over a newly painted area is avoided Running paint is an indication that the brush is being overloaded Whether you follow the sun or finish one side at a time try to finish the work at a corner of the pool to avoid laps or lines By ending in the corner where you leave off and begin will not be noticeable even if several days elapse before you return to finish B PRE AND POST PAINTING TIPS Save leftover quantities of paint a small amount is often all that is required for touch up work later Searching for a particular color can be simplified by putting a dab of paint on the pail lid before storing Use the following information when applying the paint with a sprayer If thinning never use over one pint of thinner per gallon of paint SPRAYING DATA Conventional Airless Reduction Xylene None Graco 204 275 Spray Gun DeVilbiss JGA 502 or Graco or equal equal Graco 161 191 161 Caps and or Tips 189 DeVilbiss 491D 0 017 to 0 125 or equal ee 50 to 60

7. e acid product with rubber gloves boots and goggles B SURFACE TREATMENT OF PREVIOUSLY PAINTED POOLS Before repainting your pool remove paint not in good condition i e paint that is flaking blistering cracking or chalking heavily A major cause of pool repainting failures is allowing too many old coats to build up It is generally advisable to completely remove all paint on the pool every three to four seasons or after four coats of paint are on the pool Too many coats of paint left on the pool will result in poor durability of subsequent coats It is especially important to remove all paint if cracking or alligatoring of the paint has occurred Otherwise the action of water pressure on the cracks even if they are very small will cause lifting of the paint The old paint must be completely scraped and brushed off with a wire brush by sandblasting or a paint stripper Thoroughly remove any residual stripper The pool then must be scrubbed as clean as possible to remove grease and dirt using hot water and TSP Rinse off all cleaners completely or poor paint bonding will result Old paint in good condition will show strong adhesion and uniform chalking Such surfaces may be painted without further treatment All bare and patched areas should be acid etched by using the same methods as for bare concrete discussed previously After etching the pool should be scrubbed and flushed clean with water Again it is extremely important that a

10. rfaces are by nature alkaline These alkalis which come from the lime in cement manufacture are caustic and cause corrosion They can attack and destroy paint films NATIONAL POOL FINISHES provides coatings that are alkali resistant to a high degree MOISTURE PROOF The moisture problem is twofold the applied paint film must be relatively impervious to water and at the same time should be capable of breathing to allow moisture to escape from the sub surface of the masonry Without this ability moisture drawn into the concrete surface combines with the alkali and results in corrosion between the sub surface and the paint coating NATIONAL POOL FINISHES permits moisture to escape from the pool wall through the paint without blistering or peeling and without losing its ability for water resistance ULTRAVIOLET LIGHT RESISTANCE Pool surfaces are subject to extreme amounts of sunlight which is intensified by the water Ultraviolet light tends to degrade paint But NATIONAL POOL FINISHES provides excellent resistance to sunlight CHEMICAL AND MILDEW RESISTANCE A predominate requirement for pool paint is chemical inertness NATIONAL POOL FINISHES is not deteriorated by the chemicals used in pools or by mold or fungus NATIONAL POOL FINISHES will not support the growth of micro organisms such as algae This helps to eliminate slick and slimy pool walls and floor You get greater safety anda cleaner pool Of course Swimming Pool Algaecide s

12. stimate the amount of paint needed first calculate the square feet of paintable area Next from your knowledge of the condition of the surface determine its porosity and texture estimate the square feet one gallon will cover Finally estimate the number of coats The amount of paint needed is found by multiplying the square feet of paintable area by the number of coats and dividing by the square feet one gallon will cover Approximate examples of first coat coverage are Smooth dense surface 250 300 square feet Porous rough surface 200 250 square feet The second coat usually covers approximately 300 square feet C HOW TO MIX THE PAINT The first coat on bare concrete penetrates and fills surface voids to provide a good base for the final coat On previously painted surfaces the first coat aids in binding and wetting the normal chalking of the weathered paint It forms a strong base for the finish coat Thorough mixing is critical for proper pigment dispersal Extra mixing may be required if the paint has set for some time To mix pour off most of the paint into another pail Stir that remaining in the bottom of the pail and gradually pour back the rest of the paint as the stirring progresses Stirring helos make the color and composition uniform Finally pour the paint back and forth from one container to another several times This is called boxing the paint The smooth even paint is now ready to be applied 5 STARTIN
