Painting kitchen tiles is an easy and cost-effective way to update the look of your kitchen, so long as the surface is prepped appropriately for maximum effectiveness. However, for optimal results it is crucial that all steps be taken prior to commencing any painting activity in order to guarantee long lasting results.
Start by thoroughly cleaning the tiles using sugar soap or detergent solution, followed by sanding. Sanding will give them extra grip prior to applying primer or paint.
Cleaning
If your kitchen tiles are in good condition, give them new life by painting over them with special tile paint. This can serve as an interim measure if you intend to retile later but can also serve to disguise tired existing tiles. Just remember to thoroughly clean all existing tiles prior to applying the paint and follow all product instructions closely!
Your paint stripping tools include a paint stripper (choose one that suits the type of paint you need to remove) and plastic scraper or putty knife for gently scraping off softened paint. Furthermore, be sure to wear protective clothing such as mask and gloves while working in an environment with adequate ventilation.
Select the right paint when decorating with tile surfaces; regular wall paint won’t adhere well. Look for tile-specific products which have been specially developed to resist wear and tear and last.
Primer
When painting tiles, it is vitally important to use a high-adhesion primer. This will allow the paint to adhere better, protecting against chipping and peeling over time.
Before applying a primer to tiles, they should be clean and dry. This means giving them a thorough scouring with sugar soap to remove grease, grime, or mould buildup. Once they’re clean, lightly sand them to roughen up their surfaces to help the primer better adhere to them.
Zinsser Bullseye 1-2-3, designed for interior walls and floors, is our go-to primer when painting tile surfaces. This product provides adhesion promotion, sealant application, stain resistance protection, mildew resistance as well as being ready for re-coating within an hour of application. Once dry, begin your project using painter’s tape to mark out areas not intended to be painted and ensure no unintentional tile covers become painted over!
Paint
Removing and replacing tiles can be costly endeavor, while painting can make an instantaneous change to any room without breaking the bank. The key to successful painting projects lies in choosing an appropriate paint color and surface preparation.
Start by giving the tiles a thorough cleaning to remove dirt, grease, mold or food residue. After they are dry, lightly sand them before wiping down once more to allow paint to adhere properly.
Apply a primer tailored specifically to tile, or standard acrylic latex paint. When painting large areas and edges, use a foam roller while applying several thin coats instead of one thick application allowing each to dry completely before starting over again.
Tape is essential when undertaking any paint project; use it to protect areas not being painted from accidental brush strokes and follow manufacturer drying recommendations for proper drying times before using the area again after the final coat has set completely.
Finish
Painting kitchen tiles is an effective and economical solution to giving it some color or full remodeling, providing a cost-cutting alternative to replacing them. However, this project needs careful preparation and patience.
Start by thoroughly cleansing the surface using biodegradable cleaner. Next, lightly sand it with 150-grit paper sanding paper in order to create mechanical tension that helps the paint adhere better to tiles. Rinse and dry thoroughly after each step.
Once your surface is clean and in pristine condition, apply a coat of primer. Wait for it to fully dry before beginning your paint application; make sure you use quality tile paint specifically designed for this surface type.
After your new finish has dried, be sure to apply a polyurethane sealer as a final step to protect it from moisture and other household products. Wear a respirator mask while working in an area with adequate ventilation; expect some messiness from this job and plan for it being out of commission for some time.
