Frequently asked questions

Consider the substrate you're bonding to (masonry, timber or metal studs), the weight of the plasterboard, and environmental conditions such as temperature and humidity. Also, factor in setting time and whether you need a product with gap-filling properties. 

Calculate the total surface area for adhesives or the total joint volume for sealants. For adhesives, multiply the area by the product's coverage rate. For sealants, multiply joint length by width and depth, then convert to volume. 

Add 10-15% extra for waste or variations in joint size.

Shelf life varies by product, typically ranging from 12 to 24 months when stored properly. We recommend storing products in a cool, dry place away from direct sunlight.


Adhesive

High-quality adhesives ensure that materials stay firmly in place, even under extreme conditions.

Primer

A top-notch primer helps prevent peeling, blistering and other common issues.

Filler

Professional-grade fillers efficiently repair cracks, holes and imperfections in various materials, providing a smooth foundation for paint or other finishes.

Grout

A high quality grout fills gaps between tiles and prevents moisture penetration and tile movement.

Sealant & Mastic

Reliable sealants and mastics create watertight seals around windows, doors and other potential entry points for moisture and air.

Sealer

Top-quality sealers form a protective barrier against moisture, stains and wear, particularly on porous materials like concrete and natural stone.
