Unlike in the US where DIY or "do it yourslef" is the regular norm, folks in our lovely island nation are fortunate enough according to most people, to enjoy hiring other more knowledgeable people to perform certain tasks for us at fairly reasonable prices. But nowadays, due to the popularity of numerous home improvement tv shows & the increase in local labor costs, more and more people are getting into the DIY frame of mind. So for the next few entries on my blog I have decided to give a step-by-step guide on the proper priming & painting procedures done on common surfaces in and around your home. First to be discussed in this series is the painting of new concrete surfaces. For some reason, and I am guilty of this as well, it is common for locals to refer to concrete surfaces as cemento, " Ano po ang ipipintura nyo, kahoy o cemento?". Technically cement is the main ingredient in making concrete, so my analysis of this behavior is because let's face it, cemento is much easier to say than concreto right?
step 1 - Priming - from the key word "prime" you might quickly assume that this step is all about brushing on a paint primer or as some would describe as the first coat. But priming for me is the act of preparing the concrete so that it will be compatible with your paint. A practical example would be taking a shower before getting dressed, the taking a shower would be our "priming". After your concrete has dried completely, wipe down the new wall with a semi damp cloth, after this has dried, use bristle brush or roller brush to apply on a layer of diluted masonry neutralizer (some brands like Nation paint sell diluted forms of neutralizer which are ready to use). The reason we need to apply neutralizer is because we want to neutralize the acid that is present on the concrete, this will ensure that your wall will be alkaline which is the ideal condition you are looking for, para siguradong maganda ang kapit ng pintura sa pader. Let the wall dry overnight then wipe with semi damp cloth any residue that has formed. You are now ready to apply the wall putty.

Good day to you sir! I an having problem with effloresence in my home.. Ano po ba magandang philippine brand na effloresence remover??
do i need put a neutralizer before applying waterproof like Thoroseal for example?. thanks for sharing tips.
Yap as explained here you after the cemwnt dried mostly for 24 hours, you need to apply concrete neutralizer. Then by patty or skim coat afyer dries sand paper it to smoothen then clean for remaining powder. Apply two or three coats of white flat latex followed byany color you want which is glossy paint for two or more coats.....DONE.
gud day po,pwede ko pa rin ba lagyan ng pang lason ang wall ko kahit 9mos. na yung pagkafinish ng concrete wall. thanks...
Ready mix n ba ang conc. neutralizer & apply it at once or do we need to dilute it, what ratio to dilute the solution if ever?
After applying the neutralizer, how long should I wait before I apply paint?
Hello,were you able to get an answer of your question? I have same question too.
Gaano po katagal pwede patagalin ang lason sa pader bago pinturahan. Wednesday po navlason pwede po ba mg monday ng sunod na linggo or mawawala na ang epekto ng lason? Salamat
24 hrs po saka niyo banlawan
may napanuod po ako after i apply ng neutralizer, nag antay sila ng 24hrs saka binanlawan ng tubig same process din po ng pag aapply ng neutralizer na ginamitan din ng paint roller.
Ano pong mangyayari pag nagkamali ng timpla sa concrete neutralize napasama po ang lason
Napasama po ang lason 1:8 po ratio
Of course, there is always a safety problem when there are steps. If the industrial concrete stairs being erected are Silikal, however, there is no need to be concerned. If your company has industrial concrete steps that are worn or broken off at the edges, you should be concerned. Stairs with those sticky plastic 'tabs' pasted on them to make them "safer" should also be viewed with caution; as the adage goes, they are an accident waiting to happen.
