Choosing the Wrong Primer Costs You Time & Money—Here’s How to Avoid It

-

 


If you have ever had paint peel, flash, or bleed through, chances are the problem was not your topcoat, it was your primer.

Cloverdale Paint offers a strong lineup of primers, but choosing the right one requires understanding two things:

  1. What surface or problem you are dealing with

  2. What type of primer chemistry you are using

Let’s break both down now,

Primer Types Explained: Latex, Alkyd, Shellac

Before picking a product, you need to understand what is inside the can.

Latex - Water-Based

Best for drywall, general use, low-odor environments

Pros:

  • Easy cleanup

  • Fast drying

  • Flexible, less cracking

Cons:

  • Weak stain blocking

  • Can raise wood grain

Think of it as your everyday, user-friendly option.

Alkyd - Oil-Based

Best for wood, stains, trim, and cabinets

Pros:

  • Excellent stain blocking

  • Smooth finish

  • Strong adhesion

Cons:

  • Strong smell

  • Slower drying

Think of it as the heavy-duty workhorse.

Shellac-Based

Best for smoke, fire damage, and severe stains

Pros:

  • Ultimate stain and odor blocker

  • Fastest drying

Cons:

  • Harsh fumes

  • Harder to apply

Think of it as the nuclear option, nothing gets through it.

Elastomeric or Specialty Acrylic Based

SharkSkin Primer/Sealer is not a typical primer. It is a flexible, elastomeric adhesion promoter.

  • Water-based acrylic

  • Highly flexible

  • Designed for movement and weather exposure

Think of it as a hybrid between a primer and a surface stabilizer.

SharkSkin Primer/Sealer: What Makes It Different

Product: SharkSkin Primer/Sealer
Type: Elastomeric acrylic, flexible bonding primer

What it is designed for:

  • Decks, siding, fences, and railings

  • Wood, composite, concrete, and stucco

  • Weathered or failing exterior surfaces

Key strengths:

  • Penetrates and locks down deteriorating surfaces

  • Promotes adhesion on difficult exterior substrates

  • Remains flexible to reduce cracking and peeling

  • Works on both horizontal and vertical surfaces

Limitations:

  • Transparent, not for hiding stains or color changes

  • Only meant under solid coatings, not transparent stains

  • Not a substitute for stain-blocking primers

Bottom line: SharkSkin is your go-to for exterior restoration and adhesion, not interior prep or stain blocking.

Pro Tips That Save Time and Money

  • Do not use drywall primer outside

  • Do not use SharkSkin for Semi-Transparent or Clear stains

  • If wood is cracked, weathered, or peeling, SharkSkin can extend its life dramatically

  • For cedar or tannin-heavy wood, use alkyd first and then SharkSkin with topcoat if needed

Final Takeaway

There is no one primer that fits all. The right tool for every situation is:

  • Latex for everyday interior work

  • Alkyd for wood and stain blocking

  • Shellac for extreme problem solving

  • Bonding primer for slick surfaces

  • SharkSkin for exterior durability and surface stabilization

If you are working outdoors on decks or siding, SharkSkin fills a unique gap that traditional primers cannot touch. Have more questions, contact a experienced sales associate at Chamberlain Timber Mart today.
