Buying Guide: Key Purchase Considerations
-
<li Wood type and exposure: For high-UV or coastal environments, choose a product with strong UV resistance and water-based formulas to reduce environmental impact.
<li Finish type: Semi-transparent stains preserve grain, while clear finishes emphasize natural texture; solid stains provide more color coverage but may conceal grain.
<liDurability and maintenance: Oil-based often provide deeper penetration and longer intervals between recoats; water-based options dry faster and are easier cleanup, with lower VOCs.
<liPrimer and application: Many Ready Seal products require no primer and offer simple application; some products require back brushing to avoid runs.
<liVOC and environmental impact: If eco-friendliness matters, look for low-VOC formulations and water-based systems.
<liRecoat interval and curing: Consider recoat timing and how long surfaces must stay dry before traffic resumes; some products darken as they cure.
<liCoverage and surface area: Check coverage per gallon for your deck size and plan for extras to account for texture and porosity.
<liColor stability: Some finishes change color slightly as they cure; samples or test patches can help predict final appearance.
<liMaintenance: Evaluate whether the product seals and stains in one step or requires a separate primer or prep.
