Buddy Rhodes Concrete Sealers: Quick Reference and Selection Guide

What should I seal my concrete with?

This is one of the most common questions we hear. The fact is that there is no single sealer that works for all circumstances and all users. Every sealer has pros and cons that must be considered for a given project. It is important to understand your project and know what is required of the sealer. Select the sealer that best matches the highest number of project requirements. Make a sample project and test the sealer to determine suitability.

Here are some of the factors to consider:

• Final Appearance – Should the sealer have a satin or matte finish? High build, plastic look or natural appearance? 
• Ease of Use – Is a sealer a single component wipe on material that virtually anyone can apply with little experience? Or is it multiple components where measuring and mixing are required, followed by multiple applications? Does the person applying the sealer have the experience to achieve a uniform finish without application marks? 
• Scratch Resistance – All sealers will scratch given a particular circumstance, but which ones will scratch the least? The actual surface profile of the concrete can help. Imperfections on a glossy surface will catch the light and stand out. That is why matte finishes are favorable for many surfaces, because fine scratches are less visible. Microscopic surface texture from acid etching will also help reduce visible scratching on certain topical sealers. 
• Stain Resistance – Does it allow for a spill to be left to dry without fear of a permanent stain or do certain spills need to be wiped up as they happen to protect from harm? 
• Repairability – When a blemish occurs, can a localized area be repaired and resealed, or does the entire surface need to be resealed? 
• Project Type - Is it a kitchen countertop or piece of sculpture? The sealer for each may require specific properties or method of application.
• Interior vs. Exterior - Interior surfaces are protected from the elements, take less abuse and therefore most sealers are suitable. If the project is going outdoors, topical sealers are less desirable, especially if exposed to freeze-thaw conditions.
• Suitability for a Specific Use – Does it need to hold up to the abuse of a commercial bar, or is the project intended for limited residential use?
